WEBVTT - The Shocking Vastness of Prairie , Part 2

0:00:03.000 --> 0:00:06.760
<v Speaker 1>Welcome to Stuff to Blow Your Mind production of iHeartRadio.

0:00:13.039 --> 0:00:14.920
<v Speaker 2>Hey, welcome this Stuff to Blow your Mind.

0:00:15.040 --> 0:00:18.040
<v Speaker 3>My name is Robert Lamb and I am Joe McCormick,

0:00:18.120 --> 0:00:20.400
<v Speaker 3>and we are back with the second part in our

0:00:20.480 --> 0:00:25.320
<v Speaker 3>series on the Prairie, the temperate grassland ecosystem of North America.

0:00:26.040 --> 0:00:29.880
<v Speaker 3>This subject was inspired Robbed by your recent family visit

0:00:29.920 --> 0:00:33.920
<v Speaker 3>to Colorado, spending some time in the western Prairie. I

0:00:33.920 --> 0:00:36.120
<v Speaker 3>guess this is in the region just before the landscape

0:00:36.159 --> 0:00:39.320
<v Speaker 3>turns into the rocky mountains. I couldn't remember if you

0:00:39.400 --> 0:00:42.280
<v Speaker 3>mentioned last time. Did you see bison on your trip?

0:00:42.520 --> 0:00:45.400
<v Speaker 2>We did. Yeah, at the Arsenal, we saw some bison.

0:00:45.560 --> 0:00:48.400
<v Speaker 2>Like I say that, that area has a number of

0:00:48.400 --> 0:00:52.360
<v Speaker 2>bison and there's a lot of bison conservation that is

0:00:52.960 --> 0:00:56.280
<v Speaker 2>focused there, and so we got to drive through that

0:00:56.400 --> 0:00:58.520
<v Speaker 2>area and we got to see the bison, not super

0:00:58.560 --> 0:01:00.680
<v Speaker 2>close because they're going to do exactly what they want

0:01:00.720 --> 0:01:02.640
<v Speaker 2>to do, but we still got to see them at

0:01:02.680 --> 0:01:04.000
<v Speaker 2>a distance, which was pretty cool.

0:01:04.120 --> 0:01:06.200
<v Speaker 3>It's not a petting zoo there, right right.

0:01:06.240 --> 0:01:09.360
<v Speaker 2>This is not one of those places where you hold

0:01:09.400 --> 0:01:14.800
<v Speaker 2>potatoes out your window the livestock comes over. No, No, they

0:01:14.800 --> 0:01:16.959
<v Speaker 2>do what they want and if you are close enough

0:01:17.000 --> 0:01:18.200
<v Speaker 2>to see them, and then you're lucky.

0:01:19.400 --> 0:01:22.600
<v Speaker 3>So in the previous episode of this series, we talked

0:01:22.640 --> 0:01:26.440
<v Speaker 3>about the definition of our prairie and its similarity to

0:01:26.520 --> 0:01:31.200
<v Speaker 3>other ecosystems like the step. Prairies are relatively flat or

0:01:31.319 --> 0:01:35.240
<v Speaker 3>rolling landscapes that are dominated not by trees and shrubs

0:01:35.280 --> 0:01:40.440
<v Speaker 3>but by grasses and flowering herbaceous plants called forbes, and

0:01:40.520 --> 0:01:42.319
<v Speaker 3>so one of the questions that we talked about in

0:01:42.360 --> 0:01:47.560
<v Speaker 3>the last episode somewhat extensively was why are prairies filled

0:01:47.600 --> 0:01:51.360
<v Speaker 3>with grasses and forbes instead of trees? What historically has

0:01:51.440 --> 0:01:54.720
<v Speaker 3>kept the trees out. The answer to this question turned

0:01:54.720 --> 0:01:58.800
<v Speaker 3>out to be kind of complicated, involving, but possibly not

0:01:58.960 --> 0:02:04.480
<v Speaker 3>being limited to factors of climate and rainfall, pressure from herbivores,

0:02:05.000 --> 0:02:10.040
<v Speaker 3>and very importantly, frequent fires, fires to which native grasses

0:02:10.080 --> 0:02:14.239
<v Speaker 3>and forbes are very resilient, while young trees and shrubs

0:02:14.240 --> 0:02:18.079
<v Speaker 3>are typically not. Of course, human behavior in recent centuries

0:02:18.120 --> 0:02:21.320
<v Speaker 3>has altered basically all of the factors that are upstream

0:02:21.440 --> 0:02:24.760
<v Speaker 3>of the natural plant balance, and as a result, North

0:02:24.840 --> 0:02:29.960
<v Speaker 3>America's prairies are seriously endangered. The vast majority of the

0:02:30.040 --> 0:02:33.800
<v Speaker 3>original Eastern tall grass prairie is already gone, as we

0:02:33.919 --> 0:02:37.600
<v Speaker 3>talked about last time. There are different ways of calculating

0:02:37.639 --> 0:02:41.000
<v Speaker 3>how much of it remains, but some estimates say like

0:02:41.080 --> 0:02:45.680
<v Speaker 3>four percent, others say less than one percent. It's mostly gone,

0:02:45.760 --> 0:02:49.040
<v Speaker 3>and so this is a very precious, endangered type of

0:02:49.120 --> 0:02:53.200
<v Speaker 3>landscape and there are ongoing conservation efforts to try to

0:02:53.560 --> 0:02:56.760
<v Speaker 3>return some of this landscape more to its original plant

0:02:56.800 --> 0:03:02.200
<v Speaker 3>balance and original ecosystem characteristics. After that, we went on

0:03:02.320 --> 0:03:06.520
<v Speaker 3>too a fascinating sort of historical niche subject about the prairie,

0:03:06.840 --> 0:03:10.760
<v Speaker 3>which was about grizzly bears, grizzly bears of the plains.

0:03:11.280 --> 0:03:15.239
<v Speaker 3>Today most people think of grizzlies as animals that live

0:03:15.320 --> 0:03:19.480
<v Speaker 3>exclusively in like remote mountain forests, but grizzlies used to

0:03:19.560 --> 0:03:22.360
<v Speaker 3>be apex predators of the prairie as well. And we

0:03:22.400 --> 0:03:26.320
<v Speaker 3>talked extensively about the journals of the Lewis and Clark

0:03:26.360 --> 0:03:29.280
<v Speaker 3>expedition in the early nineteenth century, which had lots of

0:03:29.360 --> 0:03:33.080
<v Speaker 3>encounters with prairie bears, and we analyzed at least one

0:03:33.120 --> 0:03:36.000
<v Speaker 3>of those encounters at length. We are back today to

0:03:36.280 --> 0:03:39.960
<v Speaker 3>talk some more. Now, Rob, I understand for today's episode

0:03:40.440 --> 0:03:43.240
<v Speaker 3>you got somewhat obsessed with prairie madness.

0:03:43.680 --> 0:03:46.040
<v Speaker 2>That's right. The other topics have had quite an effect,

0:03:46.040 --> 0:03:47.920
<v Speaker 2>but this one will drive you absolutely mad.

0:03:49.600 --> 0:03:51.280
<v Speaker 4>I'd never heard of this, you know.

0:03:51.320 --> 0:03:54.960
<v Speaker 2>I wasn't really familiar with it either, though it certainly

0:03:55.000 --> 0:03:57.400
<v Speaker 2>makes sense considering some of the things we talked about

0:03:57.440 --> 0:04:01.960
<v Speaker 2>in the last episode. On one hand, you discussed your

0:04:02.000 --> 0:04:05.880
<v Speaker 2>own personal response to the treeless openness of the prairie,

0:04:05.880 --> 0:04:09.640
<v Speaker 2>that it had maybe a sort of uncanny or even

0:04:09.760 --> 0:04:12.360
<v Speaker 2>threatening feeling to it, like, you know, too much space,

0:04:12.440 --> 0:04:13.240
<v Speaker 2>not enough trees.

0:04:14.120 --> 0:04:17.280
<v Speaker 3>Yeah, as I said in the last episode, I don't

0:04:17.400 --> 0:04:19.000
<v Speaker 3>like that I feel this way. I feel like I

0:04:19.120 --> 0:04:22.160
<v Speaker 3>want to I should be able to appreciate, you know,

0:04:22.320 --> 0:04:24.919
<v Speaker 3>the beauty of all different types of landscapes equally. But

0:04:25.040 --> 0:04:29.040
<v Speaker 3>for some reason, maybe just the environment I grew up with,

0:04:29.279 --> 0:04:31.720
<v Speaker 3>I do have a kind of bias or preference for

0:04:31.720 --> 0:04:36.760
<v Speaker 3>forested landscapes. And when there is not anything taller than

0:04:36.800 --> 0:04:40.000
<v Speaker 3>me vertically in an area and it's just you know,

0:04:40.200 --> 0:04:43.720
<v Speaker 3>vast open space all around, that does feel kind of

0:04:43.880 --> 0:04:47.800
<v Speaker 3>exposed and vulnerable and uncomfortable to me. I need tall

0:04:47.880 --> 0:04:51.600
<v Speaker 3>things around me, I think, And I don't know, maybe

0:04:51.600 --> 0:04:53.760
<v Speaker 3>this is something I could get over one day, spending

0:04:53.800 --> 0:04:54.880
<v Speaker 3>more time in the prairie.

0:04:54.960 --> 0:04:56.760
<v Speaker 4>But I do have that tree bias.

0:04:56.800 --> 0:04:59.040
<v Speaker 2>I think, well, this, I think this is going to

0:04:59.120 --> 0:05:02.000
<v Speaker 2>arguably play the scenario here. But another thing that I

0:05:02.040 --> 0:05:04.040
<v Speaker 2>think plays into the scenario that we touched on last

0:05:04.040 --> 0:05:06.680
<v Speaker 2>time is how we have a lot, a great deal

0:05:06.720 --> 0:05:10.520
<v Speaker 2>of writing and poetry about the about about the planes

0:05:10.560 --> 0:05:14.080
<v Speaker 2>the great American prairies. Particularly, we talked about the words

0:05:14.080 --> 0:05:20.240
<v Speaker 2>of William Cullen Bryant, the poet who described this sense

0:05:20.279 --> 0:05:24.840
<v Speaker 2>of awe at beholding the prairies. And yeah, I think

0:05:24.880 --> 0:05:28.760
<v Speaker 2>both of these examples steer us naturally into discussion of

0:05:29.000 --> 0:05:32.800
<v Speaker 2>prairie madness, sometimes called prairie sickness, and so forth. And

0:05:32.880 --> 0:05:35.000
<v Speaker 2>I do want to stress at the outset here. This

0:05:35.040 --> 0:05:37.560
<v Speaker 2>is not a scientific term. This is not a medical term,

0:05:38.560 --> 0:05:42.680
<v Speaker 2>and it is primarily reported as a phenomenon of the

0:05:42.760 --> 0:05:47.440
<v Speaker 2>nineteenth century, and specifically in cases where you had European

0:05:47.839 --> 0:05:53.039
<v Speaker 2>and American homesteaders, American homesteaders from the East who ventured

0:05:53.040 --> 0:05:55.279
<v Speaker 2>out onto the prairies, you know, trying to you know,

0:05:55.960 --> 0:05:59.600
<v Speaker 2>creating a new life, grabbing some land, you know, trying

0:05:59.600 --> 0:06:02.960
<v Speaker 2>to make a lot life out there, who then experienced

0:06:02.960 --> 0:06:09.600
<v Speaker 2>an array of psychological symptoms such as depression, withdrawal, behavioral changes,

0:06:09.640 --> 0:06:14.960
<v Speaker 2>and in the extremes, even violence in response to the crushing, vastness,

0:06:15.000 --> 0:06:18.719
<v Speaker 2>the open landscape and the howling wind of the prairie.

0:06:19.080 --> 0:06:20.839
<v Speaker 3>Now, based on what you were reading, would you say

0:06:20.839 --> 0:06:23.800
<v Speaker 3>that this is something that is probably culturally contingent. You

0:06:23.839 --> 0:06:29.880
<v Speaker 3>mentioned it's among like European American homesteaders, European colonizers basically

0:06:30.360 --> 0:06:33.360
<v Speaker 3>in the prairie landscape. It's not something typically reported by

0:06:33.400 --> 0:06:36.080
<v Speaker 3>like indigenous peoples of the prairies.

0:06:35.640 --> 0:06:39.880
<v Speaker 2>Correct, And that is very important to note, Like there's

0:06:39.920 --> 0:06:43.760
<v Speaker 2>been indigenous people living on the prairies for more than

0:06:43.800 --> 0:06:49.400
<v Speaker 2>ten thousand years, so this is not something that they experienced.

0:06:49.680 --> 0:06:52.600
<v Speaker 3>And so probably also not something that's like an objective

0:06:52.920 --> 0:06:56.599
<v Speaker 3>human body response to the prairie landscape. It's probably more

0:06:56.680 --> 0:06:59.120
<v Speaker 3>like a conditioned cultural type of response.

0:06:59.440 --> 0:07:01.960
<v Speaker 2>Right, if you fly into Denver, people will warn you

0:07:02.000 --> 0:07:05.800
<v Speaker 2>about the altitude difference, but nobody's going to warn you

0:07:05.839 --> 0:07:10.520
<v Speaker 2>about prairie madness because it's not really a thing in

0:07:10.600 --> 0:07:12.680
<v Speaker 2>terms of it's not something that is going to just

0:07:12.760 --> 0:07:16.520
<v Speaker 2>objectively be a factor in anyone's life. And again, it's

0:07:16.680 --> 0:07:21.720
<v Speaker 2>really mostly talked about within this particular historic context and

0:07:21.880 --> 0:07:26.800
<v Speaker 2>among particular people who were venturing out into this landscape.

0:07:26.960 --> 0:07:28.640
<v Speaker 2>And there are a number of other factors that are

0:07:28.640 --> 0:07:33.960
<v Speaker 2>involved here. So the explanation for what's going on or

0:07:34.000 --> 0:07:36.760
<v Speaker 2>allegedly went on here have more on that in a minute,

0:07:36.800 --> 0:07:41.040
<v Speaker 2>and is that you could basically underline by two examples

0:07:41.040 --> 0:07:44.000
<v Speaker 2>that we've already touched on. First, the poetic awe of

0:07:44.040 --> 0:07:47.280
<v Speaker 2>the prairie, of which there are many examples, and this

0:07:47.560 --> 0:07:50.320
<v Speaker 2>awe kind of finds its dark reflection in the fiction

0:07:50.480 --> 0:07:53.200
<v Speaker 2>and nonfiction of the time that cast the prairie is

0:07:53.200 --> 0:07:57.000
<v Speaker 2>something ominous and unnatural. Part of that is just sort

0:07:57.040 --> 0:08:00.520
<v Speaker 2>of the power of poetry and literature. If you're going

0:08:00.600 --> 0:08:03.240
<v Speaker 2>to describe a landscape, you know you're going to lean

0:08:03.280 --> 0:08:07.280
<v Speaker 2>into one direction or the other. Is it awesome and

0:08:07.320 --> 0:08:10.480
<v Speaker 2>does it make you feel like a god? Or is

0:08:10.520 --> 0:08:13.680
<v Speaker 2>there something creepy about it? It makes you feel less than

0:08:14.920 --> 0:08:18.800
<v Speaker 2>you know? Both There are you know, potentially rewarding directions

0:08:18.800 --> 0:08:22.040
<v Speaker 2>to go in in definite choices in any given work

0:08:22.080 --> 0:08:23.280
<v Speaker 2>of fiction or nonfiction.

0:08:23.600 --> 0:08:26.720
<v Speaker 3>Well, I think every landscape on earth has this this

0:08:26.840 --> 0:08:31.920
<v Speaker 3>dual quality. I mean, is the forest a soothing, calming,

0:08:32.040 --> 0:08:35.720
<v Speaker 3>shady landscape, where you are, you know, covered nicely in

0:08:35.800 --> 0:08:39.680
<v Speaker 3>these calming greens, or is it a spooky place where

0:08:39.679 --> 0:08:42.440
<v Speaker 3>you hear sounds that echo between the trees and maybe

0:08:42.480 --> 0:08:44.439
<v Speaker 3>spirits are trying to lead you off the path.

0:08:45.000 --> 0:08:47.800
<v Speaker 2>Yeah, and kind of going into something we talked about

0:08:47.880 --> 0:08:50.840
<v Speaker 2>last time. I feel like, and this is highly subjective,

0:08:50.840 --> 0:08:53.959
<v Speaker 2>but I feel like the desert environments they tend to

0:08:54.000 --> 0:08:55.880
<v Speaker 2>speak more clearly on this way, and it's like, oh,

0:08:55.880 --> 0:08:57.760
<v Speaker 2>it's a land of death, but it's alive, you know.

0:08:57.800 --> 0:08:59.960
<v Speaker 2>It seems like the back and forth there's a lot

0:09:00.120 --> 0:09:04.080
<v Speaker 2>more balanced. Prairies can maybe I'm just making them the

0:09:04.080 --> 0:09:06.800
<v Speaker 2>personal argument here that they can maybe be a bit

0:09:07.760 --> 0:09:11.640
<v Speaker 2>harder to wrap your head around because they're not barren.

0:09:11.720 --> 0:09:14.040
<v Speaker 2>They are full of life. But then there is the

0:09:14.760 --> 0:09:19.120
<v Speaker 2>more or less flat topography and some other factors environmentally

0:09:19.120 --> 0:09:21.640
<v Speaker 2>that we're going to get into here. And then the

0:09:21.640 --> 0:09:24.600
<v Speaker 2>other factor is there was this frequent observation that these

0:09:24.679 --> 0:09:29.200
<v Speaker 2>lands were fundamentally different compared to the lands that homesteaders

0:09:29.240 --> 0:09:33.880
<v Speaker 2>called home, either in the eastern United States or elsewhere

0:09:33.920 --> 0:09:37.800
<v Speaker 2>in Europe and on the literary front, some of the

0:09:38.640 --> 0:09:40.960
<v Speaker 2>some really famous examples of this, and some of the

0:09:40.960 --> 0:09:46.760
<v Speaker 2>most famous examples stem from Oliovog's nineteen twenty seven novel

0:09:46.960 --> 0:09:50.840
<v Speaker 2>Giants in the Earth. This is a book that concerns

0:09:51.400 --> 0:09:56.520
<v Speaker 2>pioneer Norwegian immigrants in the Dakota territory, with the character

0:09:56.920 --> 0:10:02.520
<v Speaker 2>Barrett Hansa particularly experiencing literary, very prairie madness. Joe, have

0:10:02.600 --> 0:10:03.520
<v Speaker 2>you ever read this book?

0:10:03.640 --> 0:10:04.320
<v Speaker 4>No, I haven't.

0:10:04.840 --> 0:10:08.520
<v Speaker 2>I had to read it in junior high or high school,

0:10:09.000 --> 0:10:11.280
<v Speaker 2>and this is one of those books that was assigned

0:10:11.280 --> 0:10:13.080
<v Speaker 2>to me, and I do not think I give it

0:10:13.080 --> 0:10:17.280
<v Speaker 2>a very dedicated reading. I remember virtually nothing of it

0:10:17.640 --> 0:10:19.719
<v Speaker 2>except for the you know, the the obvious that it

0:10:19.840 --> 0:10:22.440
<v Speaker 2>concerned no actual giants in the earth or no actual

0:10:22.640 --> 0:10:25.800
<v Speaker 2>FLM crawling out and attacking anyone.

0:10:26.720 --> 0:10:29.600
<v Speaker 4>So I really false advertising.

0:10:29.760 --> 0:10:32.680
<v Speaker 2>One star false advertising, I guess if you're in you know,

0:10:32.760 --> 0:10:35.000
<v Speaker 2>junior high or high school, well whatever age I was.

0:10:35.120 --> 0:10:38.200
<v Speaker 2>But looking back on it, and you can find the

0:10:38.240 --> 0:10:40.800
<v Speaker 2>full text online and you can, you know, find it

0:10:40.840 --> 0:10:43.520
<v Speaker 2>in print very easily to get a copy of this book.

0:10:43.559 --> 0:10:47.040
<v Speaker 2>But there are some beautiful passages that deal with this, again,

0:10:47.120 --> 0:10:52.720
<v Speaker 2>particularly concerning the character Barrett, and it's it is telling

0:10:52.920 --> 0:10:55.080
<v Speaker 2>that she's the one that experiences it because a lot

0:10:55.120 --> 0:10:59.360
<v Speaker 2>of the alleged cases of prairie madness are very gendered

0:10:59.360 --> 0:11:03.880
<v Speaker 2>in their general focusing on the housewife in a given scenario.

0:11:05.200 --> 0:11:07.440
<v Speaker 2>So I'm going to read a few passages from giants

0:11:07.440 --> 0:11:10.280
<v Speaker 2>in the earth. After they had bustled about for a

0:11:10.280 --> 0:11:13.040
<v Speaker 2>little while, the others left her. The moment they had gone,

0:11:13.080 --> 0:11:15.160
<v Speaker 2>she jumped up and crossed the tent to look out

0:11:15.200 --> 0:11:18.520
<v Speaker 2>the door. How will human beings be able to endure

0:11:18.559 --> 0:11:21.679
<v Speaker 2>this place? She thought? Why? There isn't even a thing

0:11:21.760 --> 0:11:25.480
<v Speaker 2>that one can hide behind. Her sensitive, rather beautiful face

0:11:25.640 --> 0:11:28.679
<v Speaker 2>was full of blank dismay. She turned away from the

0:11:28.720 --> 0:11:31.520
<v Speaker 2>door and began to loosen her dress. Then her eyes

0:11:31.559 --> 0:11:34.800
<v Speaker 2>fell on the center pole, with its cross piece hung

0:11:34.800 --> 0:11:38.679
<v Speaker 2>with clothes, and she stood a moment irresolute, gazing at

0:11:38.720 --> 0:11:41.880
<v Speaker 2>it in startled fright. It looked like the giants she

0:11:41.880 --> 0:11:44.240
<v Speaker 2>had read about as a child. For a long while

0:11:44.280 --> 0:11:46.800
<v Speaker 2>she was unable to banish the picture from her mind.

0:11:48.720 --> 0:11:51.000
<v Speaker 2>And then here's some more that gets I think, gets

0:11:51.000 --> 0:11:55.280
<v Speaker 2>back to the landscape. The broad expanse, stretching away endlessly

0:11:55.360 --> 0:11:58.960
<v Speaker 2>in every direction, seemed almost like the ocean, especially now

0:11:59.000 --> 0:12:02.680
<v Speaker 2>when darkness was It reminded her strongly of the sea.

0:12:02.760 --> 0:12:06.120
<v Speaker 2>And yet it was very different. The formless prairie had

0:12:06.120 --> 0:12:10.000
<v Speaker 2>no heart that beat, no waves that's sang, no soul

0:12:10.120 --> 0:12:14.080
<v Speaker 2>that could be touched or cared. And then one more here,

0:12:14.800 --> 0:12:17.800
<v Speaker 2>but more to be dreaded than this tribulation was the

0:12:17.880 --> 0:12:22.520
<v Speaker 2>strange spell of sadness which the unbroken solitude cast upon

0:12:22.559 --> 0:12:26.640
<v Speaker 2>the minds of some. Many took their own lives asylum.

0:12:26.679 --> 0:12:30.800
<v Speaker 2>After asylum was filled with disordered beings who had once

0:12:30.880 --> 0:12:33.600
<v Speaker 2>been human. It is hard for the eye to wander

0:12:33.600 --> 0:12:37.400
<v Speaker 2>from skyline to skyline year in and year out without

0:12:37.480 --> 0:12:38.840
<v Speaker 2>finding a resting place.

0:12:40.240 --> 0:12:42.040
<v Speaker 3>Well, that sounds pretty extreme.

0:12:42.840 --> 0:12:45.680
<v Speaker 2>Yeah, and I think we'll come back to this, but

0:12:45.960 --> 0:12:49.359
<v Speaker 2>I think everyone can. Certainly, if you have any familiarity

0:12:49.400 --> 0:12:52.120
<v Speaker 2>with the literature, you can definitely pick up on Gothic

0:12:52.240 --> 0:12:57.080
<v Speaker 2>tendencies in this writing. Really latching onto this idea. I

0:12:57.120 --> 0:12:59.960
<v Speaker 2>referenced our recent Weird House cinema selection in the Mouth

0:13:00.040 --> 0:13:03.520
<v Speaker 2>of Madness earlier, and these passages could very easily be

0:13:03.640 --> 0:13:06.679
<v Speaker 2>passages that Sutter Kane has written about. You know, the

0:13:06.760 --> 0:13:09.240
<v Speaker 2>void opening up in Monsters, spilling out of it. You know,

0:13:09.240 --> 0:13:11.120
<v Speaker 2>it's that level of darkness.

0:13:11.920 --> 0:13:15.320
<v Speaker 3>I don't know what the author's intention here is, whether

0:13:15.400 --> 0:13:19.920
<v Speaker 3>it's to actually project these characteristics onto the landscape, or

0:13:19.960 --> 0:13:23.000
<v Speaker 3>to do what sometimes happens in fiction, which is to

0:13:23.160 --> 0:13:28.880
<v Speaker 3>show what are really characteristics of the human character of

0:13:28.960 --> 0:13:32.440
<v Speaker 3>the character, and they are reading their own psyche onto

0:13:32.480 --> 0:13:35.120
<v Speaker 3>the landscape. It might not actually be something that is

0:13:35.480 --> 0:13:38.720
<v Speaker 3>the landscape's fault, if that makes any sense. It's the

0:13:38.800 --> 0:13:41.760
<v Speaker 3>person is having feelings and they're looking at the world

0:13:41.800 --> 0:13:44.280
<v Speaker 3>around them, and they see their feelings in the world.

0:13:44.960 --> 0:13:47.120
<v Speaker 2>Yeah. Again, it's been too long since I read it

0:13:47.400 --> 0:13:50.719
<v Speaker 2>to provide full context here, but it's my understanding that

0:13:51.400 --> 0:13:55.160
<v Speaker 2>most of these ideas are centered in this particular character,

0:13:55.600 --> 0:13:58.120
<v Speaker 2>and that it's not present in other characters. So I

0:13:58.120 --> 0:13:59.760
<v Speaker 2>think it is very character focused here.

0:14:00.120 --> 0:14:00.679
<v Speaker 4>Yeah.

0:14:00.800 --> 0:14:02.679
<v Speaker 2>So there are other examples from this book. I might

0:14:02.679 --> 0:14:06.120
<v Speaker 2>come back and read another line from it. But all

0:14:06.160 --> 0:14:08.720
<v Speaker 2>of this effectively underlies the idea that there was something

0:14:08.760 --> 0:14:12.880
<v Speaker 2>about the landscape or the contrast of landscape, combined with

0:14:13.040 --> 0:14:17.920
<v Speaker 2>isolation and the severity of frontier life that could lead

0:14:18.120 --> 0:14:22.440
<v Speaker 2>to mental breakdown in some and the topic seems to

0:14:22.560 --> 0:14:26.600
<v Speaker 2>have entered the larger American consciousness in eighteen ninety three

0:14:26.960 --> 0:14:31.160
<v Speaker 2>three via the paper or the publication The Isolation of

0:14:31.240 --> 0:14:35.840
<v Speaker 2>Life on Prairie Farms by E. V. Smaali sm A L. L. E.

0:14:36.040 --> 0:14:39.000
<v Speaker 2>Y published in the Atlantic and still available on the

0:14:39.040 --> 0:14:42.040
<v Speaker 2>Atlantic's website. You can pull it up. I think there's

0:14:42.440 --> 0:14:44.200
<v Speaker 2>a paywall if you want to read it in full,

0:14:44.320 --> 0:14:47.160
<v Speaker 2>but you can also click and look at a scanned

0:14:47.280 --> 0:14:48.800
<v Speaker 2>version of it as it printed. And that's how I

0:14:48.880 --> 0:14:49.120
<v Speaker 2>read it.

0:14:49.840 --> 0:14:50.560
<v Speaker 4>Read it in full.

0:14:51.880 --> 0:14:55.760
<v Speaker 2>This individual, EV Smally was an American journalist, editor, and

0:14:55.920 --> 0:14:58.960
<v Speaker 2>Republican political writer, closely tied at the time to US

0:14:59.040 --> 0:15:02.960
<v Speaker 2>President James A. I'm going to read a few samples

0:15:03.000 --> 0:15:05.560
<v Speaker 2>from this just to give everyone the vibe. Okay. It

0:15:05.960 --> 0:15:09.280
<v Speaker 2>more or less begins with the following In no civilized

0:15:09.320 --> 0:15:12.440
<v Speaker 2>country have the cultivators of the soil adapted their home

0:15:12.520 --> 0:15:15.640
<v Speaker 2>life so badly to the conditions of nature as have

0:15:15.800 --> 0:15:20.440
<v Speaker 2>the people of our great northwestern prairies. Okay, Yeah, And

0:15:20.600 --> 0:15:23.320
<v Speaker 2>from there he goes on to argue that the like

0:15:23.440 --> 0:15:26.000
<v Speaker 2>there are some there's some arguments here that I don't

0:15:26.040 --> 0:15:29.640
<v Speaker 2>think really stand up to close scrutiny, including the idea

0:15:29.720 --> 0:15:32.640
<v Speaker 2>that the European peasant. He refers to the quote European

0:15:32.680 --> 0:15:36.400
<v Speaker 2>peasant as a type of person who lived a life

0:15:36.440 --> 0:15:40.360
<v Speaker 2>of joy and social interaction and that on the and

0:15:40.480 --> 0:15:43.480
<v Speaker 2>that prairie dwellers essentially had none of this and were

0:15:43.560 --> 0:15:50.160
<v Speaker 2>basically doomed. Here's another passage. An alarming amount of insanity

0:15:50.240 --> 0:15:53.600
<v Speaker 2>occurs in the New Prairie States among farmers and their wives.

0:15:54.160 --> 0:15:58.280
<v Speaker 2>In proportion to their numbers, the Scandinavian settlers furnished the

0:15:58.400 --> 0:16:03.040
<v Speaker 2>largest contingent to the The reason is not far to seek.

0:16:03.440 --> 0:16:06.760
<v Speaker 2>These people came from cheery, little farm villages. Life in

0:16:06.840 --> 0:16:10.400
<v Speaker 2>the Fatherland was hard and toilsome, but it was not lonesome.

0:16:11.080 --> 0:16:15.240
<v Speaker 3>Oh well, I don't know if there's like actual experiment

0:16:15.320 --> 0:16:17.520
<v Speaker 3>to back this up, but it seems plausible to me

0:16:17.840 --> 0:16:22.120
<v Speaker 3>that loneliness and isolation could be a major contributor to

0:16:22.160 --> 0:16:23.960
<v Speaker 3>people having psychological problems.

0:16:24.880 --> 0:16:28.880
<v Speaker 2>Yeah, and that is certainly a possibility here. Like, one

0:16:28.920 --> 0:16:33.000
<v Speaker 2>of the realities is that you did have these homesteaders

0:16:33.120 --> 0:16:36.880
<v Speaker 2>going out living in very isolated circumstances and living a

0:16:37.280 --> 0:16:40.160
<v Speaker 2>hard life in an environment that they were not accustomed

0:16:40.200 --> 0:16:44.480
<v Speaker 2>to different environmental factors that we'll get into here. So yeah,

0:16:44.960 --> 0:16:46.840
<v Speaker 2>I want to stress that, even though I'm having some

0:16:46.960 --> 0:16:49.720
<v Speaker 2>fun with the way that this is written, and also

0:16:50.160 --> 0:16:52.120
<v Speaker 2>certainly singling out that this is a paper that made

0:16:52.160 --> 0:16:55.480
<v Speaker 2>a big impact on how people thought about prairie madness. Yeah,

0:16:55.560 --> 0:16:57.920
<v Speaker 2>not everything in here should just be dismissed. Like there

0:16:57.960 --> 0:17:00.800
<v Speaker 2>are some possible connections to be made here.

0:17:01.360 --> 0:17:03.720
<v Speaker 3>Yeah, I mean, like it even strikes me as possible

0:17:03.760 --> 0:17:05.320
<v Speaker 3>to pick up on something I was saying about the

0:17:05.400 --> 0:17:11.480
<v Speaker 3>characters in that novel that one could easily read psychological

0:17:12.040 --> 0:17:17.080
<v Speaker 3>difficulty stemming from, say, loneliness and isolation. Could you know,

0:17:17.359 --> 0:17:21.800
<v Speaker 3>take those problems and interpret them as problems related to

0:17:22.000 --> 0:17:24.760
<v Speaker 3>the landscape, when really maybe the landscape doesn't have that

0:17:24.960 --> 0:17:27.480
<v Speaker 3>much do with it. It's just like what you're looking

0:17:27.560 --> 0:17:29.920
<v Speaker 3>at while you're feeling the fact that you don't have

0:17:30.000 --> 0:17:32.960
<v Speaker 3>any friends and haven't seen anybody but your husband and years.

0:17:33.359 --> 0:17:37.240
<v Speaker 2>Yeah, yeah, yeah, exactly. You're a few more quotes though,

0:17:37.280 --> 0:17:41.720
<v Speaker 2>from this paper quote the silence of death rests on

0:17:41.840 --> 0:17:45.360
<v Speaker 2>the vast landscape, save when it is swept by cruel winds.

0:17:46.600 --> 0:17:49.800
<v Speaker 2>And then here's one more. There is but one remedy

0:17:49.920 --> 0:17:52.359
<v Speaker 2>for the dreariness of farm life on the prairies. The

0:17:52.520 --> 0:17:56.080
<v Speaker 2>isolated farmhouse must be abandoned, and the people must drawl

0:17:56.160 --> 0:17:59.399
<v Speaker 2>together in villages. The peasants of the Russian steps did

0:17:59.440 --> 0:18:02.040
<v Speaker 2>this century years ago, and so did the dwellers of

0:18:02.080 --> 0:18:06.639
<v Speaker 2>the Great Danubian Plane. And so he ultimately positions isolated

0:18:06.720 --> 0:18:09.280
<v Speaker 2>life on the frontier plane as standing in just stark

0:18:09.320 --> 0:18:14.240
<v Speaker 2>opposition to sanity, to intellectual development, and just the rational

0:18:14.320 --> 0:18:18.840
<v Speaker 2>progression of society. So he's not the final word on

0:18:18.920 --> 0:18:21.480
<v Speaker 2>all of this. And there have been some papers that

0:18:21.600 --> 0:18:23.920
<v Speaker 2>have really gone into this and looked at it in

0:18:24.000 --> 0:18:28.359
<v Speaker 2>different ways, looking at it as a literary trope, looking

0:18:28.480 --> 0:18:32.679
<v Speaker 2>at it and as it may connect to sensory deprivation

0:18:33.400 --> 0:18:37.399
<v Speaker 2>and so forth. I was looking at a particular paper,

0:18:37.520 --> 0:18:41.800
<v Speaker 2>This is Unsettling Landscapes, Prairie Madness and Eco Gothic Themes

0:18:41.840 --> 0:18:45.600
<v Speaker 2>in US Plains Literature, published in Great Planes Quarterly from

0:18:45.640 --> 0:18:51.119
<v Speaker 2>twenty nineteen by Vanessa stein Rotter, And in this she

0:18:51.240 --> 0:18:54.080
<v Speaker 2>points out that prairie madness is of course a recurring

0:18:54.119 --> 0:18:56.880
<v Speaker 2>theme in the fiction and poetry of the US Great Plains,

0:18:57.200 --> 0:18:59.000
<v Speaker 2>and the author stressed various ways that the feature of

0:18:59.000 --> 0:19:03.119
<v Speaker 2>the plain's environment stabilized non native settlers sense of place

0:19:03.320 --> 0:19:06.320
<v Speaker 2>and control. So she points out that this was of course,

0:19:06.520 --> 0:19:09.680
<v Speaker 2>again not a medical phenomenon, This was not a scientific term,

0:19:10.160 --> 0:19:14.159
<v Speaker 2>and she also citing the work of Sarah Brooks. Sundberg

0:19:15.080 --> 0:19:18.240
<v Speaker 2>points out the cases of white female settler mental and

0:19:18.440 --> 0:19:21.359
<v Speaker 2>or emotional decline in the prairie might not have actually

0:19:21.480 --> 0:19:25.280
<v Speaker 2>been that widespread. But even though we see this all

0:19:25.320 --> 0:19:27.200
<v Speaker 2>the time with things, even though there may not have

0:19:27.280 --> 0:19:30.439
<v Speaker 2>been as many cases of it, it became an idea

0:19:30.560 --> 0:19:33.520
<v Speaker 2>that was difficult to dispel. It became a popular way

0:19:33.640 --> 0:19:37.440
<v Speaker 2>of thinking about life on the prairies because again, outside

0:19:37.520 --> 0:19:40.080
<v Speaker 2>of the actual environments of people living out there, you

0:19:40.160 --> 0:19:43.240
<v Speaker 2>had people, say, reading that article in the Atlantic or

0:19:43.320 --> 0:19:47.440
<v Speaker 2>reading poetry and fiction that drove home this Gothic idea,

0:19:47.920 --> 0:19:51.159
<v Speaker 2>and therefore it becomes very difficult to shake, and it

0:19:51.280 --> 0:19:54.840
<v Speaker 2>just becomes a staple of fiction and nonfiction writings of

0:19:54.880 --> 0:19:56.040
<v Speaker 2>the time about the Prairies.

0:19:56.600 --> 0:20:00.520
<v Speaker 3>How prevalent we think a problem is often has little

0:20:00.600 --> 0:20:03.600
<v Speaker 3>to do with the raw numbers of how often it's occurring.

0:20:03.760 --> 0:20:06.119
<v Speaker 3>Often it has more to do with like how sticky

0:20:06.200 --> 0:20:10.320
<v Speaker 3>the idea is? Is it like really interesting or scary

0:20:10.640 --> 0:20:13.160
<v Speaker 3>or captivating to the imagination.

0:20:12.760 --> 0:20:13.879
<v Speaker 4>In some way? Right?

0:20:13.960 --> 0:20:15.920
<v Speaker 2>And of course we see a more pronounced version of

0:20:16.000 --> 0:20:19.200
<v Speaker 2>that when things become actual social panics, you know, so

0:20:19.280 --> 0:20:23.880
<v Speaker 2>for instance, satanic panic, the idea there's the satanic forces

0:20:23.920 --> 0:20:27.680
<v Speaker 2>at work in the world today. We've we've done episodes

0:20:27.720 --> 0:20:30.040
<v Speaker 2>about this before. In this case, I don't think that

0:20:30.200 --> 0:20:33.439
<v Speaker 2>prairie madness ever reached a level of true social panic,

0:20:33.960 --> 0:20:36.320
<v Speaker 2>but it just becomes this sort of sticky idea.

0:20:36.760 --> 0:20:36.960
<v Speaker 4>Yeah.

0:20:37.520 --> 0:20:40.359
<v Speaker 2>So, the author here points out that fiction writers were

0:20:40.440 --> 0:20:44.800
<v Speaker 2>especially drawn to the idea because of those terrific Gothic undertones,

0:20:45.600 --> 0:20:49.439
<v Speaker 2>as well as quote its potential to engage larger, often

0:20:49.600 --> 0:20:54.480
<v Speaker 2>gendered anxieties or feelings of powerlessness within restrictive social and

0:20:54.600 --> 0:20:55.639
<v Speaker 2>cultural roles.

0:20:56.480 --> 0:20:56.680
<v Speaker 4>Yeah.

0:20:57.000 --> 0:20:58.680
<v Speaker 2>So, and I think there's a case to be made

0:20:58.720 --> 0:21:00.639
<v Speaker 2>that that's maybe what we see in and Giants in

0:21:00.720 --> 0:21:03.639
<v Speaker 2>the Earth. You know, it's not just about spooky landscape

0:21:03.680 --> 0:21:06.320
<v Speaker 2>making people feel spooky, but maybe getting into some of

0:21:06.359 --> 0:21:11.520
<v Speaker 2>these deeper concepts. Steinroder focuses on the landscape's role in

0:21:11.560 --> 0:21:14.320
<v Speaker 2>the scenario, but points out that other scholars have examined

0:21:14.320 --> 0:21:19.159
<v Speaker 2>the importance of gender and family relationships, domestic violence, and

0:21:19.320 --> 0:21:22.680
<v Speaker 2>cultural and physical isolation that are often bound up in

0:21:22.720 --> 0:21:25.200
<v Speaker 2>the scenario. So again, any as we've been alluding to

0:21:25.400 --> 0:21:30.600
<v Speaker 2>any given potential case of prairie madness, any individual experience

0:21:30.680 --> 0:21:34.600
<v Speaker 2>that could be chalked up as being prairie madness. They're

0:21:34.680 --> 0:21:37.720
<v Speaker 2>going to be, They're potentially all these other factors as well,

0:21:37.880 --> 0:21:40.560
<v Speaker 2>and again just potentially a hard life as well. I

0:21:40.680 --> 0:21:44.520
<v Speaker 2>was reading some of the settler accounts of how frightening

0:21:44.960 --> 0:21:47.639
<v Speaker 2>prairie fires could be. You know, we touched on that already,

0:21:47.760 --> 0:21:51.160
<v Speaker 2>just the idea that like a fast moving fire could

0:21:51.240 --> 0:21:53.240
<v Speaker 2>just rip across the prairie.

0:21:53.960 --> 0:21:54.639
<v Speaker 4>Yeah, totally.

0:21:54.720 --> 0:21:57.280
<v Speaker 3>And as we talked about in the last episode, fear

0:21:57.440 --> 0:21:59.800
<v Speaker 3>of these prairie fires and what they would bring the

0:22:00.080 --> 0:22:05.280
<v Speaker 3>led to attempts by European American settlers of the planes

0:22:05.359 --> 0:22:09.280
<v Speaker 3>to suppress naturally occurring prairie fires to stop them from spreading,

0:22:09.640 --> 0:22:13.560
<v Speaker 3>which actually ended up being very harmful to the prairie ecosystem.

0:22:14.440 --> 0:22:19.120
<v Speaker 3>You know, the indigenous peoples of the Great Plains more

0:22:19.240 --> 0:22:24.399
<v Speaker 3>often intentionally both used intentionally set prairie fires in some

0:22:24.560 --> 0:22:27.640
<v Speaker 3>cases for like the management of bison prey and things

0:22:27.720 --> 0:22:30.560
<v Speaker 3>like that, and also allowed them to occur more, which

0:22:30.720 --> 0:22:33.359
<v Speaker 3>was much healthier for the prairie because, as we know,

0:22:33.720 --> 0:22:36.400
<v Speaker 3>the natural plant balance depends on the fires.

0:22:37.040 --> 0:22:38.680
<v Speaker 2>Yes, absolutely.

0:22:48.200 --> 0:22:48.240
<v Speaker 1>So.

0:22:48.359 --> 0:22:52.320
<v Speaker 2>Steinroder again focuses on the landscape's role, and I'm just

0:22:52.400 --> 0:22:55.679
<v Speaker 2>going to boil like our key findings down here are

0:22:55.760 --> 0:22:57.840
<v Speaker 2>key arguments, and that is that the features of the

0:22:57.960 --> 0:23:02.760
<v Speaker 2>landscape can destabilize one sense of control. It can make

0:23:03.200 --> 0:23:07.240
<v Speaker 2>it feel like you are not a complete autonomous agent

0:23:07.840 --> 0:23:11.760
<v Speaker 2>in this kind of humanless wilderness. That and that also

0:23:11.840 --> 0:23:15.920
<v Speaker 2>it can just be very difficult to just comprehend the

0:23:16.040 --> 0:23:19.600
<v Speaker 2>landscape around you, that there's something ineffable about it, and

0:23:19.760 --> 0:23:22.240
<v Speaker 2>that that can can also feel kind of crushing.

0:23:22.880 --> 0:23:23.560
<v Speaker 4>Yeah, totally.

0:23:24.160 --> 0:23:26.280
<v Speaker 2>Now, I think the same could probably be argued about

0:23:26.359 --> 0:23:31.400
<v Speaker 2>various other landscapes, and you know, you could probably apply

0:23:31.560 --> 0:23:32.879
<v Speaker 2>this to things that we might think of as the

0:23:32.960 --> 0:23:37.520
<v Speaker 2>opposite of the prairie, like the mountains. But still, I

0:23:37.600 --> 0:23:39.000
<v Speaker 2>think it's an interesting argument.

0:23:39.520 --> 0:23:39.680
<v Speaker 1>You know.

0:23:39.720 --> 0:23:42.399
<v Speaker 2>I think she's acknowledging all these other factors and also

0:23:42.560 --> 0:23:45.679
<v Speaker 2>the idea that there may have been far fewer cases

0:23:45.720 --> 0:23:49.280
<v Speaker 2>of this than we actually think. But the landscape definitely

0:23:49.359 --> 0:23:52.880
<v Speaker 2>plays a role either in the cases or our idea

0:23:53.000 --> 0:23:55.520
<v Speaker 2>about these cases. I want to turn to another paper

0:23:55.640 --> 0:23:58.400
<v Speaker 2>I was looking at here. This one's by Alex d. Veles,

0:23:58.840 --> 0:24:02.480
<v Speaker 2>titled The Wind Cries The Effect of Soundscape on the

0:24:02.560 --> 0:24:06.480
<v Speaker 2>Prairie Madness Phenomenon. This is from twenty twenty two in

0:24:06.880 --> 0:24:14.440
<v Speaker 2>historical archaeology, and this one basically talks about the possibility

0:24:15.119 --> 0:24:21.520
<v Speaker 2>that you could have specific details of the sounds of

0:24:21.640 --> 0:24:24.119
<v Speaker 2>the prairie that could have been like a catalyst for

0:24:24.240 --> 0:24:29.960
<v Speaker 2>prairie madness, so something in those howling winds, for example.

0:24:30.680 --> 0:24:33.720
<v Speaker 2>There's a paywall in this particular paper, but James Gaines

0:24:33.760 --> 0:24:37.320
<v Speaker 2>wrote a good piece about it for Atlas Obscura the

0:24:37.400 --> 0:24:41.040
<v Speaker 2>same year, and I recommend that as well. Okay, so

0:24:41.359 --> 0:24:46.840
<v Speaker 2>veils examined human hearing patterns and spectral data on Great

0:24:47.080 --> 0:24:51.240
<v Speaker 2>Planes soundscapes. Now, to be clear, these are like contemporary soundscapes,

0:24:51.280 --> 0:24:54.359
<v Speaker 2>and one of the things that is outlined in that

0:24:54.480 --> 0:24:57.399
<v Speaker 2>Alice Obscure article is that you know, it would have

0:24:57.440 --> 0:25:01.400
<v Speaker 2>been different back in these days. We changed the environment

0:25:01.760 --> 0:25:04.200
<v Speaker 2>quite a bit. So it's possible that, you know, what

0:25:04.560 --> 0:25:07.159
<v Speaker 2>he's studying here, wouldn't you know, one hundred percent be

0:25:07.720 --> 0:25:10.560
<v Speaker 2>the environment that the settlers found themselves in. But any

0:25:10.640 --> 0:25:15.199
<v Speaker 2>rate examines these things, ultimately proposing that affected settlers might

0:25:15.240 --> 0:25:19.360
<v Speaker 2>have suffered from misophonia or hyperacusis, thus making them more

0:25:19.480 --> 0:25:25.560
<v Speaker 2>sensitive to environmental sounds and with both conditions worsened by stress. Again,

0:25:26.280 --> 0:25:30.000
<v Speaker 2>stressful environment potentially in and of itself, not counting social factors,

0:25:30.680 --> 0:25:33.520
<v Speaker 2>and you know in the author also links some of

0:25:33.600 --> 0:25:36.040
<v Speaker 2>this to some of the symptoms described in the literature

0:25:36.119 --> 0:25:40.280
<v Speaker 2>on prairie madness, such as in the extreme's depression, insomnia,

0:25:40.680 --> 0:25:45.399
<v Speaker 2>irrational behavior, and so forth. So the focus here was

0:25:45.440 --> 0:25:50.480
<v Speaker 2>on low frequency environmental noise, which can potentially overstimulate the

0:25:50.560 --> 0:25:54.679
<v Speaker 2>nervous system in certain individuals, as well as those continuous

0:25:54.800 --> 0:25:58.840
<v Speaker 2>or supposed to continuous roaring winds out across the prairie.

0:25:59.359 --> 0:26:03.320
<v Speaker 2>And as points out that every landscape that humans live

0:26:03.359 --> 0:26:06.040
<v Speaker 2>in has plenty of sounds for us to hear, but

0:26:06.200 --> 0:26:09.560
<v Speaker 2>that in cities these sounds are more diverse and essentially

0:26:09.640 --> 0:26:11.840
<v Speaker 2>become a kind of white noise. I think a lot

0:26:11.880 --> 0:26:14.639
<v Speaker 2>of us that live in cities we can speak to this.

0:26:14.800 --> 0:26:14.960
<v Speaker 4>You know.

0:26:15.080 --> 0:26:17.480
<v Speaker 2>You just get used to the sort of bustle of

0:26:18.680 --> 0:26:20.639
<v Speaker 2>say a large urban environment, and a lot of it

0:26:20.720 --> 0:26:23.240
<v Speaker 2>fades into the background. Yeah, I mean you still there'll

0:26:23.240 --> 0:26:26.240
<v Speaker 2>be things like horns and so forth. It still can

0:26:27.359 --> 0:26:29.240
<v Speaker 2>get your attention and throw you off, but for the

0:26:29.280 --> 0:26:33.680
<v Speaker 2>most part, it all just kind of becomes the background noise. Meanwhile,

0:26:33.760 --> 0:26:38.359
<v Speaker 2>on the planes, especially in these historic settings, there's less

0:26:38.520 --> 0:26:42.760
<v Speaker 2>background then, and the sounds that do exist. They coincide

0:26:42.800 --> 0:26:45.000
<v Speaker 2>with a sensitive range of human hearing that the brain

0:26:45.080 --> 0:26:49.879
<v Speaker 2>pays more attention to interesting, so gains in that Atlas

0:26:49.920 --> 0:26:53.040
<v Speaker 2>obscure piece on This also cites Adrian K. C Lee

0:26:53.160 --> 0:26:56.320
<v Speaker 2>and auditory brain scientists at the University of Washington who

0:26:56.359 --> 0:27:00.639
<v Speaker 2>said that the sound environment reminded them of since redeprivation

0:27:00.880 --> 0:27:06.440
<v Speaker 2>chambers as well as anechoic chambers zero echo chambers. And

0:27:06.560 --> 0:27:09.399
<v Speaker 2>these are cases where we have sonic environments that have

0:27:09.520 --> 0:27:11.520
<v Speaker 2>been engineered in a way that they can cause the

0:27:11.560 --> 0:27:16.040
<v Speaker 2>brain to quote naturally adapt to its environment, essentially turning

0:27:16.160 --> 0:27:19.840
<v Speaker 2>up or down the volume to better distinguish what's going on.

0:27:20.960 --> 0:27:23.920
<v Speaker 3>I don't know how well validated this is, but I

0:27:24.000 --> 0:27:28.120
<v Speaker 3>at least recall reading anecdotal reports that anichoic chambers can

0:27:28.240 --> 0:27:32.000
<v Speaker 3>make people feel very uncomfortable. Yeah, like going in them

0:27:32.160 --> 0:27:35.560
<v Speaker 3>after a while, Like the sound environment is literally unnerving.

0:27:35.640 --> 0:27:38.119
<v Speaker 3>People don't like it, and it makes them feel weird

0:27:38.160 --> 0:27:38.480
<v Speaker 3>and they.

0:27:38.480 --> 0:27:39.040
<v Speaker 4>Need to leave.

0:27:39.760 --> 0:27:39.960
<v Speaker 1>Yeah.

0:27:40.240 --> 0:27:43.520
<v Speaker 2>Yeah, so this level of weirdness could potentially creep in.

0:27:43.840 --> 0:27:45.960
<v Speaker 2>You start hearing all sorts of things that interfere with

0:27:46.040 --> 0:27:51.080
<v Speaker 2>your slumber. Really almoso kind of induced misophonia. So you know,

0:27:51.160 --> 0:27:54.400
<v Speaker 2>you might be hearing the sound of like, you know, insects,

0:27:54.520 --> 0:27:57.359
<v Speaker 2>or the wind you know outside, like you know, hitting

0:27:57.480 --> 0:28:00.480
<v Speaker 2>parts of the external structure of the house, that sort

0:28:00.480 --> 0:28:04.840
<v Speaker 2>of thing. So, you know, I think it is it's

0:28:04.880 --> 0:28:06.840
<v Speaker 2>an interesting idea. I think, you know, that we do

0:28:07.000 --> 0:28:09.000
<v Speaker 2>have to remind ourselves not that we shouldn't place too

0:28:09.080 --> 0:28:12.680
<v Speaker 2>much emphasis on a singular type of stimuli. And I

0:28:12.760 --> 0:28:15.080
<v Speaker 2>don't think that's ultimately what the author, the original author

0:28:15.200 --> 0:28:17.200
<v Speaker 2>was arguing here, but they were just saying, look, here's

0:28:17.359 --> 0:28:21.040
<v Speaker 2>just one potential piece of the puzzle that could have

0:28:21.160 --> 0:28:25.720
<v Speaker 2>played such a factor. And the winds, you know, absolutely

0:28:26.200 --> 0:28:28.159
<v Speaker 2>could have been a factor. We touched on the prairie

0:28:28.200 --> 0:28:32.120
<v Speaker 2>winds already in this series. The winds can be seasonally

0:28:32.200 --> 0:28:35.800
<v Speaker 2>quite intense, especially in March and April, but also anytime

0:28:35.880 --> 0:28:39.400
<v Speaker 2>you have temperature contrasts driving large scale weather systems across

0:28:39.440 --> 0:28:43.760
<v Speaker 2>the plains, and the natural habitat again offers virtually nothing

0:28:43.800 --> 0:28:47.120
<v Speaker 2>in the way of wind breaks. So you'll find localized

0:28:47.160 --> 0:28:49.720
<v Speaker 2>areas of higher wind in the United States and Canada

0:28:49.760 --> 0:28:52.720
<v Speaker 2>and certainly during pronounced storms, but on a statewide level,

0:28:53.080 --> 0:28:58.440
<v Speaker 2>the Great Planes represent the largest continuous windy environment due

0:28:58.440 --> 0:29:01.360
<v Speaker 2>to these just vast, unobstruct did flat terrains, and that

0:29:01.400 --> 0:29:06.320
<v Speaker 2>would have especially been the case historically before these landscapes

0:29:06.360 --> 0:29:09.720
<v Speaker 2>were reduced. Though again we have to remind ourself of

0:29:09.800 --> 0:29:14.360
<v Speaker 2>the subjective nature of such things. So turning back to poetry,

0:29:14.400 --> 0:29:18.080
<v Speaker 2>I just want to present two examples of authors describing

0:29:18.240 --> 0:29:21.920
<v Speaker 2>prairie wind. The first is from Giants in the Earth

0:29:22.680 --> 0:29:23.880
<v Speaker 2>that I already referenced.

0:29:25.000 --> 0:29:27.280
<v Speaker 3>Barrett, can I guess this passage is going to be

0:29:27.360 --> 0:29:29.360
<v Speaker 3>not a fan of the prairie wind.

0:29:30.840 --> 0:29:33.160
<v Speaker 2>Yeah, especially since it concerns the same character. That's a

0:29:33.200 --> 0:29:33.560
<v Speaker 2>good bet.

0:29:33.680 --> 0:29:34.360
<v Speaker 4>Okay.

0:29:34.760 --> 0:29:36.760
<v Speaker 2>Barrett could not go to sleep for a long time

0:29:36.880 --> 0:29:40.320
<v Speaker 2>that night. At last, she grew thoroughly angry with herself.

0:29:40.920 --> 0:29:44.560
<v Speaker 2>Her nerves were taught as bowstrings. Her head kept rising

0:29:44.720 --> 0:29:47.160
<v Speaker 2>up from the pillow to listen, but there was nothing

0:29:47.200 --> 0:29:50.320
<v Speaker 2>to hear, nothing except the night wind, which now had

0:29:50.360 --> 0:29:53.959
<v Speaker 2>begun to stir. It stirred with so many unknown things.

0:29:55.200 --> 0:29:56.600
<v Speaker 4>Okay, so not.

0:29:57.360 --> 0:30:01.320
<v Speaker 2>An endorsement of the prairie wind. But then I want

0:30:01.360 --> 0:30:04.880
<v Speaker 2>to read just a couple of stanzas here from Prairie Winds,

0:30:05.080 --> 0:30:08.040
<v Speaker 2>a poem by Helena Coleman, who lived eighteen sixty nine

0:30:08.080 --> 0:30:11.760
<v Speaker 2>through nineteen fifty three, a Canadian poet, and you can

0:30:11.840 --> 0:30:14.360
<v Speaker 2>look this up online. This poem is available in full

0:30:14.440 --> 0:30:18.160
<v Speaker 2>at all poetry dot com. I love all things that

0:30:18.280 --> 0:30:21.200
<v Speaker 2>God has made that show his ordered care and might,

0:30:21.680 --> 0:30:24.720
<v Speaker 2>But most I think I love the wind that blows

0:30:24.760 --> 0:30:28.640
<v Speaker 2>at night. It holds so much mystery, like that in

0:30:28.800 --> 0:30:32.480
<v Speaker 2>mine own restless heart, brother to me and well beloved,

0:30:33.000 --> 0:30:38.760
<v Speaker 2>O wind thou art, So here we is a divine

0:30:39.600 --> 0:30:43.840
<v Speaker 2>wind on the prairie, inspiring wind on the prairie, as

0:30:43.880 --> 0:30:48.400
<v Speaker 2>opposed to the night wind that contains unknown threats. So again,

0:30:48.480 --> 0:30:52.640
<v Speaker 2>it's also very subjective and then can be tweaked. It

0:30:52.720 --> 0:30:54.920
<v Speaker 2>e's a direction with the language, with the poetry.

0:30:55.520 --> 0:30:58.200
<v Speaker 3>I like how both of them appeal to the mystery

0:30:58.320 --> 0:31:00.960
<v Speaker 3>in the wind, except in one case the mystery seems

0:31:01.000 --> 0:31:03.680
<v Speaker 3>threatening and the other case the mystery is I don't know,

0:31:03.840 --> 0:31:05.920
<v Speaker 3>so the divine possibilities unknown.

0:31:06.400 --> 0:31:08.920
<v Speaker 2>Yeah, And I do want a flag too that in

0:31:09.080 --> 0:31:11.520
<v Speaker 2>these various discussions of prairie madness that you find, sometimes

0:31:11.560 --> 0:31:14.000
<v Speaker 2>they're talking about the roar of the wind, the sound

0:31:14.080 --> 0:31:15.480
<v Speaker 2>of the wind, and other times you're talking about the

0:31:15.520 --> 0:31:18.760
<v Speaker 2>silence of the great plains. So I don't know. I

0:31:18.800 --> 0:31:20.800
<v Speaker 2>guess there is kind of a maybe it's both of

0:31:20.880 --> 0:31:23.440
<v Speaker 2>those working together, you know, where you're maybe having these

0:31:23.560 --> 0:31:25.960
<v Speaker 2>contrasts where you're like, how can this place be so

0:31:26.120 --> 0:31:29.719
<v Speaker 2>empty and so loud, and then later it feels silent

0:31:29.800 --> 0:31:32.000
<v Speaker 2>as well. So I think all of this is fascinating.

0:31:32.040 --> 0:31:34.120
<v Speaker 2>I don't think any of it suggests like an equation

0:31:34.760 --> 0:31:37.920
<v Speaker 2>for prairie madness that you know holds one hundred percent true.

0:31:38.440 --> 0:31:42.040
<v Speaker 2>But we can identify these various the various themes that

0:31:42.120 --> 0:31:47.240
<v Speaker 2>become popular about it, and these infectious thoughts regarding prairie madness,

0:31:47.360 --> 0:31:49.520
<v Speaker 2>and we can identify some of the factors that may

0:31:49.560 --> 0:31:55.200
<v Speaker 2>have played a role in any actual historic examples where

0:31:55.440 --> 0:32:00.360
<v Speaker 2>people's mental state was pushed in a negative direction, maybe

0:32:00.440 --> 0:32:03.240
<v Speaker 2>in part because of the landscape or because of the

0:32:03.720 --> 0:32:07.280
<v Speaker 2>other details of the environment. Yeah, I know that we

0:32:07.480 --> 0:32:11.040
<v Speaker 2>have no we have We probably don't have anything like

0:32:11.120 --> 0:32:14.120
<v Speaker 2>a true pioneer of the of the of the frontier

0:32:14.200 --> 0:32:16.560
<v Speaker 2>prairie out out there listening that can chime in here.

0:32:16.640 --> 0:32:20.000
<v Speaker 2>But I'm sure we have some listeners who moved to

0:32:20.280 --> 0:32:24.920
<v Speaker 2>the Great Plains from other areas, maybe lived in more

0:32:25.000 --> 0:32:28.280
<v Speaker 2>isolated locations, who can maybe speak to a little of

0:32:28.360 --> 0:32:32.160
<v Speaker 2>this or certainly can apply their own experiences to these

0:32:32.240 --> 0:32:34.640
<v Speaker 2>examples of prairie madness, and you can give us a

0:32:34.680 --> 0:32:39.120
<v Speaker 2>little field report. Yeah, I did not experience anything like

0:32:39.240 --> 0:32:42.080
<v Speaker 2>prairie madness when I in my very brief experience as

0:32:42.080 --> 0:32:45.920
<v Speaker 2>a tourist checking out the prairies. I just I found

0:32:45.960 --> 0:32:48.880
<v Speaker 2>it all fascinating. Maybe a little hot at times, it's

0:32:49.000 --> 0:32:53.360
<v Speaker 2>very sunny out there, but yeah, I didn't feel anything

0:32:53.440 --> 0:32:54.400
<v Speaker 2>like prairie madness.

0:32:54.960 --> 0:33:08.240
<v Speaker 3>Well, I'm glad to hear that. Are you ready to

0:33:08.520 --> 0:33:11.080
<v Speaker 3>talk about the tangent I went on for this episode?

0:33:11.960 --> 0:33:13.400
<v Speaker 2>Yeah? Yeah, what have you got for us?

0:33:13.800 --> 0:33:14.120
<v Speaker 4>Okay?

0:33:14.240 --> 0:33:18.520
<v Speaker 3>So I got sucked into a little geological or you

0:33:18.600 --> 0:33:22.920
<v Speaker 3>might even call it a topographical mystery related to specific

0:33:23.040 --> 0:33:26.720
<v Speaker 3>prairie landscapes, and that is the mystery of the so

0:33:26.960 --> 0:33:32.360
<v Speaker 3>called Mima Mounds, named after the Mima Prairie in southwest

0:33:32.520 --> 0:33:36.240
<v Speaker 3>Washington State, which is now a protected area at US

0:33:36.360 --> 0:33:42.840
<v Speaker 3>National Natural Landmark. So the word Mima Spelledma originally comes

0:33:42.920 --> 0:33:46.800
<v Speaker 3>from the language of the Shahalis tribe, in which mima

0:33:47.040 --> 0:33:50.880
<v Speaker 3>means newness, as in something that is new and is

0:33:51.080 --> 0:33:53.800
<v Speaker 3>related to or at least sounds like a word in

0:33:53.880 --> 0:33:54.800
<v Speaker 3>the same language that.

0:33:54.920 --> 0:33:56.360
<v Speaker 4>Means to be surprised.

0:33:57.520 --> 0:33:59.720
<v Speaker 3>I was reading about this in multiple sources, but I

0:34:00.400 --> 0:34:02.840
<v Speaker 3>especially want to shout out. So I was looking at

0:34:02.880 --> 0:34:04.920
<v Speaker 3>some like technical papers and stuff, but I want to

0:34:04.920 --> 0:34:08.520
<v Speaker 3>shout out a short informational booklet I think, mostly geared

0:34:08.560 --> 0:34:12.520
<v Speaker 3>towards students, put together by the Washington Geological Survey, which

0:34:12.600 --> 0:34:14.279
<v Speaker 3>is great to look up if you want to see

0:34:14.360 --> 0:34:17.719
<v Speaker 3>illustrations and you want easy to understand explanations of the

0:34:17.800 --> 0:34:23.360
<v Speaker 3>main theories behind these formations. So what are the Mima mounds?

0:34:24.080 --> 0:34:27.200
<v Speaker 3>A mundane way of putting it is that they are

0:34:27.560 --> 0:34:32.840
<v Speaker 3>little hills, lots of little hills crowded together. Now, initially

0:34:33.200 --> 0:34:36.600
<v Speaker 3>that probably doesn't sound very intriguing or mysterious, but I

0:34:36.680 --> 0:34:40.360
<v Speaker 3>think you will immediately grasp what is interesting if you

0:34:40.480 --> 0:34:43.080
<v Speaker 3>look at a picture of them. So, Rob, I've got

0:34:43.120 --> 0:34:45.160
<v Speaker 3>some pictures for you to look at in the outline.

0:34:45.200 --> 0:34:48.960
<v Speaker 3>Here this first one. In the outline, you can see

0:34:49.000 --> 0:34:52.160
<v Speaker 3>the nice green landscape, but all of these hills. This

0:34:52.320 --> 0:34:54.720
<v Speaker 3>is a photo from one of the sites in Washington State,

0:34:55.320 --> 0:34:58.240
<v Speaker 3>and what we see is a vast field of several

0:34:58.320 --> 0:35:03.400
<v Speaker 3>square miles full of little hills, each between two and

0:35:03.560 --> 0:35:07.280
<v Speaker 3>seven feet tall and between eight and forty feet wide,

0:35:07.719 --> 0:35:11.719
<v Speaker 3>covered in prairie grass and flowering herbs, and occasionally with

0:35:11.840 --> 0:35:14.680
<v Speaker 3>little trees or shrubs growing on them, but mostly not

0:35:14.880 --> 0:35:20.080
<v Speaker 3>mostly just this grassy landscape with these basically evenly spaced

0:35:20.200 --> 0:35:26.440
<v Speaker 3>little hills. These hills sometimes get called soil pimples or

0:35:26.600 --> 0:35:30.080
<v Speaker 3>even goose bumps on the earth, and that comparison makes

0:35:30.200 --> 0:35:33.120
<v Speaker 3>even more sense if you look at them from above

0:35:34.080 --> 0:35:39.080
<v Speaker 3>from imagery that's created using aerial photography or other top

0:35:39.160 --> 0:35:42.839
<v Speaker 3>down imaging methods like lidar from above and rob I've

0:35:42.880 --> 0:35:44.960
<v Speaker 3>got a couple of images of this that you can

0:35:45.040 --> 0:35:47.480
<v Speaker 3>look at in the outline as well. We'll describe these

0:35:47.560 --> 0:35:50.320
<v Speaker 3>for people listening at home. So the first one is

0:35:50.360 --> 0:35:53.040
<v Speaker 3>a photograph taken from above, and then the second one

0:35:53.200 --> 0:35:54.520
<v Speaker 3>is a lidar image.

0:35:55.480 --> 0:35:57.120
<v Speaker 4>And looking from above when.

0:35:57.040 --> 0:36:01.320
<v Speaker 3>You're not distracted by other surface features like plants or buildings,

0:36:01.880 --> 0:36:04.000
<v Speaker 3>you know what it looks like To me? It looks

0:36:04.160 --> 0:36:08.080
<v Speaker 3>like the skin of a beaded lizard. It really does, yes,

0:36:09.440 --> 0:36:13.319
<v Speaker 3>So the mima mounds are squeezed together into the landscape

0:36:13.800 --> 0:36:18.600
<v Speaker 3>in a way that feels both regular and irregular. Irregular

0:36:18.680 --> 0:36:21.719
<v Speaker 3>in the sense that they are not in rows that

0:36:22.000 --> 0:36:25.240
<v Speaker 3>line up or anything like that. It's not a repeating pattern,

0:36:26.000 --> 0:36:28.400
<v Speaker 3>but they feel regular in the sense that they are

0:36:28.600 --> 0:36:32.680
<v Speaker 3>crowded together without significant gaps, and the spaces between them

0:36:33.360 --> 0:36:37.680
<v Speaker 3>feel like they are confined to a regular, very small size.

0:36:38.640 --> 0:36:40.319
<v Speaker 3>It looks kind I was trying to think of an

0:36:40.320 --> 0:36:42.919
<v Speaker 3>analogy to picture. It looks kind of like what would

0:36:42.960 --> 0:36:47.360
<v Speaker 3>happen if you got a bunch of different but similarly

0:36:47.600 --> 0:36:50.120
<v Speaker 3>sized coins and you put them all down on a

0:36:50.239 --> 0:36:53.400
<v Speaker 3>table lying flat, and then you push the mass of

0:36:53.480 --> 0:36:56.720
<v Speaker 3>coins together from the outside of the of the mass,

0:36:57.200 --> 0:37:00.440
<v Speaker 3>so that this pile of coins has like or no

0:37:00.600 --> 0:37:03.200
<v Speaker 3>space in between the coins, but they're not overlapping.

0:37:04.760 --> 0:37:08.200
<v Speaker 2>Yeah, yeah, I get what you're laying down here. Yeah,

0:37:08.280 --> 0:37:12.080
<v Speaker 2>something about just you know, how tightly compact everything is,

0:37:12.600 --> 0:37:16.960
<v Speaker 2>like the bumps or mounds or not uniform in their

0:37:17.120 --> 0:37:20.520
<v Speaker 2>size exactly, but yeah, they seem to there is this

0:37:20.600 --> 0:37:21.759
<v Speaker 2>feeling that they are bunched together.

0:37:23.000 --> 0:37:23.200
<v Speaker 4>Yeah.

0:37:23.440 --> 0:37:25.880
<v Speaker 3>Now another thing is if you're thinking hills, you might

0:37:25.960 --> 0:37:27.960
<v Speaker 3>be getting the wrong idea because these do not have

0:37:28.160 --> 0:37:32.320
<v Speaker 3>the long, rolling, natural feeling of hills in the traditional

0:37:32.440 --> 0:37:34.239
<v Speaker 3>sense like you would see in the you know, the

0:37:34.320 --> 0:37:38.920
<v Speaker 3>foothills of a mountain range or you know, most naturally

0:37:39.000 --> 0:37:43.040
<v Speaker 3>occurring hills. Something about them, maybe the way that they're

0:37:43.080 --> 0:37:44.400
<v Speaker 3>relatively small and.

0:37:44.560 --> 0:37:45.920
<v Speaker 4>Tightly packed together.

0:37:46.280 --> 0:37:49.680
<v Speaker 3>It feels unique, unique from most hills. And yet they

0:37:49.680 --> 0:37:54.879
<v Speaker 3>are not totally unique as features or geological formations. If

0:37:54.920 --> 0:37:57.920
<v Speaker 3>you dig them up and look inside them, they are

0:37:58.120 --> 0:38:03.840
<v Speaker 3>these small piles of silt, sand, and pebbles, and similar

0:38:03.960 --> 0:38:08.960
<v Speaker 3>patterns of small hills and mounds, sometimes with similar constituents

0:38:09.000 --> 0:38:12.960
<v Speaker 3>inside them, also called Mima mounds. Even when they're not

0:38:13.360 --> 0:38:17.240
<v Speaker 3>inside the Mama Prairie region, or called Mima like mounds,

0:38:17.360 --> 0:38:20.320
<v Speaker 3>these similar mounds can be found in other places in

0:38:20.440 --> 0:38:24.319
<v Speaker 3>North America and even on other continents. So there are

0:38:24.320 --> 0:38:27.560
<v Speaker 3>a bunch of different places beyond the Mama Prairie where

0:38:27.640 --> 0:38:31.440
<v Speaker 3>you will find Mima like mounds. And there's still debate

0:38:31.680 --> 0:38:36.040
<v Speaker 3>about some of these formations. We actually don't know if

0:38:36.080 --> 0:38:38.960
<v Speaker 3>they are all truly the same type of feature with

0:38:39.040 --> 0:38:43.520
<v Speaker 3>the same underlying cause, or if they're only superficially similar

0:38:43.719 --> 0:38:47.280
<v Speaker 3>goosebumps in the earth with different causes. Now that brings

0:38:47.360 --> 0:38:49.879
<v Speaker 3>us to the question of what is the cause? How

0:38:50.040 --> 0:38:53.560
<v Speaker 3>were these hundreds of little mounds formed? And we still

0:38:53.600 --> 0:38:57.160
<v Speaker 3>don't know. This is an open scientific question. And I

0:38:57.200 --> 0:38:59.640
<v Speaker 3>thought it might be interesting to do a brief look

0:38:59.719 --> 0:39:03.399
<v Speaker 3>at few of the competing hypotheses. I can't promise I've

0:39:03.480 --> 0:39:07.239
<v Speaker 3>captured all of the hypotheses in circulation today, but I

0:39:07.320 --> 0:39:09.879
<v Speaker 3>think I've got the main ones that are out there

0:39:09.960 --> 0:39:11.520
<v Speaker 3>now and have been out there in the past.

0:39:11.800 --> 0:39:15.240
<v Speaker 2>But to be clear, UFOs write out non ufis.

0:39:15.640 --> 0:39:17.759
<v Speaker 3>Obviously, some people are going to say that anything that

0:39:17.960 --> 0:39:21.240
<v Speaker 3>looks weird or interesting, and these do look weird and interesting.

0:39:21.680 --> 0:39:25.200
<v Speaker 3>Somebody's going to say, yeah, that's the that's crop circle type.

0:39:25.040 --> 0:39:27.360
<v Speaker 4>Thing, landing zone. I don't know.

0:39:27.400 --> 0:39:29.160
<v Speaker 3>Maybe this is where the Aliens they were going to

0:39:29.239 --> 0:39:31.560
<v Speaker 3>build some pyramids, but they gave up early.

0:39:32.000 --> 0:39:32.600
<v Speaker 4>I don't know that.

0:39:32.880 --> 0:39:35.600
<v Speaker 3>But yes, the ufologists are going to be on this,

0:39:36.000 --> 0:39:37.879
<v Speaker 3>But no, that is not That is not a good

0:39:37.920 --> 0:39:39.000
<v Speaker 3>theory in my opinion.

0:39:39.280 --> 0:39:42.080
<v Speaker 2>And then at the same time, we shouldn't, like surface level,

0:39:42.160 --> 0:39:45.759
<v Speaker 2>confuse these with nouns and like the mound builders and

0:39:45.960 --> 0:39:49.000
<v Speaker 2>mounds elsewhere in the America, is that it seemed to

0:39:49.000 --> 0:39:53.600
<v Speaker 2>have definitely had an origin in human construction by indigenous peoples.

0:39:54.520 --> 0:39:56.880
<v Speaker 3>No, from what I was reading that they do not

0:39:57.120 --> 0:40:00.000
<v Speaker 3>seem to have major characteristics of mounds built by human

0:40:00.400 --> 0:40:04.160
<v Speaker 3>and so human construction is not one of the leading theories,

0:40:04.200 --> 0:40:06.240
<v Speaker 3>at least in any of the sources I was finding.

0:40:06.880 --> 0:40:09.080
<v Speaker 3>People may have thought that a long time ago, but

0:40:09.920 --> 0:40:13.040
<v Speaker 3>not in modern science. So let's go through some of

0:40:13.080 --> 0:40:16.279
<v Speaker 3>these hypotheses about how they were formed. One is the

0:40:16.520 --> 0:40:21.080
<v Speaker 3>so called sun cup hypothesis. This was originally proposed by

0:40:21.120 --> 0:40:25.000
<v Speaker 3>a geologist named J. Harlan Bretts in the year nineteen thirteen.

0:40:25.560 --> 0:40:29.360
<v Speaker 3>Bretts specialized in the geological history of the Pacific Northwest,

0:40:29.440 --> 0:40:32.640
<v Speaker 3>and he studied how the landscape had been shaped by

0:40:32.719 --> 0:40:38.440
<v Speaker 3>glaciers and by glacial outburst floods. A glacial outburst flood

0:40:39.120 --> 0:40:43.120
<v Speaker 3>is a flood caused when a glacier lake suddenly breaks

0:40:43.200 --> 0:40:46.560
<v Speaker 3>free of its containing structure. Essentially, there's a natural dam

0:40:46.719 --> 0:40:49.040
<v Speaker 3>of some kind, maybe made of ice or of earth,

0:40:49.480 --> 0:40:52.960
<v Speaker 3>that gives way, and then this huge lake of glacial

0:40:53.160 --> 0:40:57.320
<v Speaker 3>meltwater is released onto the lands below. And so the

0:40:57.440 --> 0:41:01.640
<v Speaker 3>sun cup hypothesis goes like this. Thousands of years ago,

0:41:02.719 --> 0:41:07.040
<v Speaker 3>the surrounding area, especially this big vast landscape just north

0:41:07.280 --> 0:41:11.480
<v Speaker 3>of the Mima Prairie, was covered in a glacier, and

0:41:11.680 --> 0:41:15.960
<v Speaker 3>the Mima Prairie itself became blanketed in a thin sheet

0:41:16.120 --> 0:41:20.360
<v Speaker 3>of ice and snow, and the sun shined down on

0:41:20.680 --> 0:41:23.600
<v Speaker 3>these thin sheets of ice and snow in the relevant

0:41:23.680 --> 0:41:29.440
<v Speaker 3>areas and melted them in irregular patterns called sun cups.

0:41:30.000 --> 0:41:33.560
<v Speaker 3>You can actually watch sun cups form on patches of

0:41:33.680 --> 0:41:37.320
<v Speaker 3>snow melting in the sun today. There are these irregular

0:41:37.400 --> 0:41:41.440
<v Speaker 3>patterns of differential melting that look kind of like inverse goosebumps,

0:41:41.520 --> 0:41:46.760
<v Speaker 3>little depressions or cups crowded together like a random honeycomb pattern.

0:41:47.400 --> 0:41:48.960
<v Speaker 3>So Rob, I've got a picture for you to look

0:41:49.000 --> 0:41:50.880
<v Speaker 3>at in the outline here. But folks at home, you

0:41:50.960 --> 0:41:53.080
<v Speaker 3>can google sun cups in snow if you want to

0:41:53.120 --> 0:41:56.480
<v Speaker 3>see it. You've probably seen something like this yourself before.

0:41:56.600 --> 0:42:00.000
<v Speaker 3>Maybe a little of shaded patch of snow or something

0:42:00.080 --> 0:42:03.880
<v Speaker 3>thing lingers for a while, it gets beamed on by

0:42:03.920 --> 0:42:07.000
<v Speaker 3>the sun over and over, partially melts and then refreezes,

0:42:07.160 --> 0:42:09.600
<v Speaker 3>that kind of thing, and you get these these little

0:42:10.200 --> 0:42:12.919
<v Speaker 3>these patterns of cups and depressions in the ice.

0:42:13.239 --> 0:42:17.600
<v Speaker 2>Yeah, if you live in areas that gets received snowfall,

0:42:17.719 --> 0:42:19.719
<v Speaker 2>then you've probably seen this before. You just didn't know

0:42:19.760 --> 0:42:20.319
<v Speaker 2>what it was called.

0:42:20.640 --> 0:42:24.840
<v Speaker 3>Yeah, So Brett's argued you had something like this happening.

0:42:25.000 --> 0:42:27.399
<v Speaker 3>This big layer of snow and ice over the top

0:42:27.480 --> 0:42:32.080
<v Speaker 3>of this prairie. And then water flowed over the top

0:42:32.239 --> 0:42:35.200
<v Speaker 3>of this ice that had had these sun cups forming

0:42:35.280 --> 0:42:37.880
<v Speaker 3>in it. So maybe this is from a you know,

0:42:38.239 --> 0:42:40.799
<v Speaker 3>maybe a glacial outburst, flood or something. You know, water

0:42:40.920 --> 0:42:43.560
<v Speaker 3>flows over the top, and as it flows over the

0:42:43.600 --> 0:42:48.000
<v Speaker 3>top of this ice, it deposits sediment such as silt, sand,

0:42:48.120 --> 0:42:52.960
<v Speaker 3>and pebbles or gravel in the cups, and this keeps happening.

0:42:53.040 --> 0:42:56.440
<v Speaker 3>Over time, the deposits in the sun cups build up

0:42:56.560 --> 0:43:01.880
<v Speaker 3>and become quite large. Then the landscape the ice melts away,

0:43:02.080 --> 0:43:06.120
<v Speaker 3>so the cups are now gone, leaving only the deposits behind.

0:43:06.360 --> 0:43:10.040
<v Speaker 3>So what had once been piles of sediment accumulating in

0:43:10.120 --> 0:43:13.640
<v Speaker 3>the bottom of these ice cups now become little hills

0:43:13.760 --> 0:43:17.439
<v Speaker 3>with no ice cups. One that I want to mention

0:43:17.600 --> 0:43:19.879
<v Speaker 3>that from what I can tell, is not really still

0:43:19.880 --> 0:43:23.080
<v Speaker 3>in the mix anymore, but it was historically important was

0:43:23.239 --> 0:43:27.800
<v Speaker 3>the frost polygon hypothesis. Apparently in the mid twentieth century,

0:43:27.840 --> 0:43:31.480
<v Speaker 3>it was a popular explanation to say that frost polygons

0:43:31.520 --> 0:43:34.759
<v Speaker 3>had formed the mounds, and the idea goes like this,

0:43:35.200 --> 0:43:39.600
<v Speaker 3>you have frozen soil that cracks in a polygon pattern.

0:43:40.400 --> 0:43:44.360
<v Speaker 3>You've again you've probably seen something like this yourself. Actually,

0:43:44.880 --> 0:43:48.239
<v Speaker 3>you may have seen images of polygonal cracking in dry

0:43:48.480 --> 0:43:51.960
<v Speaker 3>or frozen soil. You think about like soil that gets

0:43:52.000 --> 0:43:54.600
<v Speaker 3>wet and then gets parched and dries out, it cracks

0:43:54.640 --> 0:43:57.680
<v Speaker 3>in these kind of weird again, kind of honeycomb like pattern.

0:43:58.200 --> 0:44:01.400
<v Speaker 2>Yeah, this reminds me their actual There are these texture

0:44:01.480 --> 0:44:04.640
<v Speaker 2>paints you can get. These are used in the miniature

0:44:04.640 --> 0:44:08.480
<v Speaker 2>painting and all, where you lay this sort of thick

0:44:08.640 --> 0:44:12.520
<v Speaker 2>paint with like little grains in it. You lay this

0:44:12.640 --> 0:44:15.440
<v Speaker 2>out over like the base that a miniature like human

0:44:15.560 --> 0:44:17.880
<v Speaker 2>soldier is going to be standing on, and then as

0:44:17.920 --> 0:44:21.239
<v Speaker 2>it dries, it actually like breaks up like this. And

0:44:21.360 --> 0:44:24.680
<v Speaker 2>it's not necessarily like completely you know, you're not just

0:44:24.840 --> 0:44:27.759
<v Speaker 2>saying polygons necessarily, but the way it breaks up, you

0:44:27.800 --> 0:44:31.280
<v Speaker 2>get these little gaps and it creates this wonderful effect

0:44:31.400 --> 0:44:33.080
<v Speaker 2>where it looks like dried earth.

0:44:33.400 --> 0:44:34.960
<v Speaker 4>Yeah, cool, cracked landscape.

0:44:35.080 --> 0:44:35.239
<v Speaker 1>Yeah.

0:44:35.600 --> 0:44:35.839
<v Speaker 4>Yeah.

0:44:35.960 --> 0:44:38.160
<v Speaker 3>So you can actually have a similar thing to that

0:44:38.480 --> 0:44:42.280
<v Speaker 3>happening with icy soil ice that you know, it freezes

0:44:42.880 --> 0:44:47.280
<v Speaker 3>and then it cracks and inside these cracks. The idea

0:44:47.440 --> 0:44:50.840
<v Speaker 3>wind with the frost polygon hypothesis. Inside these cracks they

0:44:50.840 --> 0:44:54.200
<v Speaker 3>would fill with rain water or maybe floodwater. They'd fill

0:44:54.320 --> 0:44:57.560
<v Speaker 3>up with water and then freeze again, and so the

0:44:57.760 --> 0:45:00.920
<v Speaker 3>freezing would cause the water track in the cracks to

0:45:01.120 --> 0:45:04.480
<v Speaker 3>expand each time, because water expands when it freezes, and

0:45:04.600 --> 0:45:07.440
<v Speaker 3>this would widen the cracks. So it freezes pushes the

0:45:07.520 --> 0:45:11.239
<v Speaker 3>soil away to the sides, and as a result of

0:45:11.320 --> 0:45:15.320
<v Speaker 3>this process you get like freezing and then warming, and

0:45:15.360 --> 0:45:17.840
<v Speaker 3>then the warming conditions would melt away the ice and

0:45:17.960 --> 0:45:21.000
<v Speaker 3>when it flowed away, it would leave these large spaces

0:45:21.080 --> 0:45:24.359
<v Speaker 3>in between rounded mounds that had been pushed up by

0:45:24.440 --> 0:45:28.400
<v Speaker 3>the expanding frost. Apparently, there was a big geological conference

0:45:28.440 --> 0:45:32.120
<v Speaker 3>in the eighties which examined this hypothesis and concluded that

0:45:32.280 --> 0:45:35.160
<v Speaker 3>it could not adequately explain at least some of the mounds.

0:45:35.200 --> 0:45:38.040
<v Speaker 3>So I think this is not a major contender for

0:45:38.120 --> 0:45:54.439
<v Speaker 3>the explanation anymore. Another idea is the vegetation anchoring hypothesis.

0:45:55.280 --> 0:45:59.600
<v Speaker 3>The Washington Geological Survey booklet calls this the runoff erosion

0:45:59.760 --> 0:46:04.200
<v Speaker 3>roof anchor hypothesis. But the common feature of these explanations

0:46:04.480 --> 0:46:08.160
<v Speaker 3>is that there are plants growing on the prairie and

0:46:08.360 --> 0:46:11.600
<v Speaker 3>the roots of these plants grip the soil and help

0:46:11.680 --> 0:46:16.480
<v Speaker 3>protect it from erosion, and the mounds in this hypothesis

0:46:16.520 --> 0:46:20.680
<v Speaker 3>would represent places where plant roots once held the soil together,

0:46:21.239 --> 0:46:27.080
<v Speaker 3>while channels were carved around the mounds by surrounding soil erosion. Okay,

0:46:28.239 --> 0:46:33.040
<v Speaker 3>then we get another hypothesis. This one's interesting gophers. So

0:46:33.400 --> 0:46:36.760
<v Speaker 3>in nineteen forty two, a couple of biologists named Walter

0:46:36.920 --> 0:46:40.879
<v Speaker 3>Dohlquest and Victor Scheffer proposed that it could have been

0:46:41.239 --> 0:46:46.640
<v Speaker 3>bioturbation by gophers. So how would gophers have built these mounds?

0:46:46.680 --> 0:46:51.560
<v Speaker 3>Don't they dig tunnels underground? How would that result in mounds? Well,

0:46:51.760 --> 0:46:55.160
<v Speaker 3>the idea goes like this. When gophers dig tunnels, they

0:46:55.239 --> 0:46:58.880
<v Speaker 3>displace soil. That soil has to go somewhere, so they

0:46:58.960 --> 0:47:01.399
<v Speaker 3>dig out cavities in the earth, and then they throw

0:47:01.560 --> 0:47:05.239
<v Speaker 3>the displaced soil into a pile behind them, and this

0:47:05.440 --> 0:47:08.920
<v Speaker 3>excavated soil gets packed into a big mound. And these

0:47:08.960 --> 0:47:12.160
<v Speaker 3>piles can actually they're not just waste. They can be

0:47:12.360 --> 0:47:16.160
<v Speaker 3>useful to the gophers because then when a rainstorm comes,

0:47:16.480 --> 0:47:19.520
<v Speaker 3>the gophers now have high ground they can retreat to

0:47:19.760 --> 0:47:22.840
<v Speaker 3>to get away from the flood. And if you study

0:47:22.960 --> 0:47:27.320
<v Speaker 3>gopher behavior. This hypothesis says gophers actually tend to space

0:47:27.440 --> 0:47:31.880
<v Speaker 3>their burrows a fairly reliable distance apart from one another,

0:47:32.680 --> 0:47:36.440
<v Speaker 3>though not in exactly like regular patterns or rows. And

0:47:36.560 --> 0:47:39.440
<v Speaker 3>this spacing could match up roughly with the spacing and

0:47:39.560 --> 0:47:41.920
<v Speaker 3>irregular arrangement of the Mima Mounds.

0:47:42.640 --> 0:47:45.240
<v Speaker 2>Okay, so the idea here being yeah, that the Mima

0:47:45.280 --> 0:47:49.520
<v Speaker 2>mount spacing is a visual representation of gopher territories.

0:47:49.960 --> 0:47:52.800
<v Speaker 3>Yes, and I believe this hypothesis is still in the

0:47:52.840 --> 0:47:57.520
<v Speaker 3>mix as well, could be gopher related. Another hypothesis is

0:47:57.800 --> 0:48:02.560
<v Speaker 3>glacial outburst flooding. So it's worth mentioning. I think I

0:48:02.640 --> 0:48:04.760
<v Speaker 3>said this a little while ago, but the Myma Prairie

0:48:05.000 --> 0:48:08.400
<v Speaker 3>is right at the southern edge of where a giant

0:48:08.680 --> 0:48:12.640
<v Speaker 3>glacier reached down to about sixteen thousand years ago, and

0:48:13.120 --> 0:48:16.759
<v Speaker 3>some researchers think that the Mima Mounds could have been

0:48:16.960 --> 0:48:20.360
<v Speaker 3>formed by here. This concept is coming back a glacial

0:48:20.480 --> 0:48:25.840
<v Speaker 3>outburst flood from the glacially damned lake known as Lake Carbon.

0:48:26.280 --> 0:48:30.279
<v Speaker 3>So around this time this Lake Carbon somehow spilled out

0:48:30.320 --> 0:48:34.560
<v Speaker 3>of its containment, it flooded the landscape, and as it

0:48:34.680 --> 0:48:37.440
<v Speaker 3>did so, it picked up tons of volcanic rocks and

0:48:37.600 --> 0:48:42.200
<v Speaker 3>sediment from the Cascade Mountains and washed them downstream, leaving

0:48:42.280 --> 0:48:45.359
<v Speaker 3>them in piles along the path of the flood. Now,

0:48:45.480 --> 0:48:48.040
<v Speaker 3>what would be the evidence that the mounds could come

0:48:48.080 --> 0:48:52.120
<v Speaker 3>from this event? One thing cited by that Washington Geological

0:48:52.200 --> 0:48:54.560
<v Speaker 3>Survey booklet is that you've got mounds in a place

0:48:54.600 --> 0:48:58.480
<v Speaker 3>called Rocky Prairie upstream from the area of the Mima

0:48:58.560 --> 0:49:01.319
<v Speaker 3>Prairie upstream in the what this flood zone would have been.

0:49:02.320 --> 0:49:06.280
<v Speaker 3>And these mounds have more volcanic rocks and bigger rocks,

0:49:07.000 --> 0:49:10.640
<v Speaker 3>and then the Mama Prairie mounds downstream have smaller rocks

0:49:10.760 --> 0:49:15.239
<v Speaker 3>and smaller, finer sediment. And that pattern, you know, the

0:49:15.280 --> 0:49:19.160
<v Speaker 3>bigger rocks upstream, more volcanic rocks, and the smaller sediment downstream,

0:49:19.440 --> 0:49:23.000
<v Speaker 3>that would fit with a flood formation mechanism. Also, the

0:49:23.120 --> 0:49:27.080
<v Speaker 3>mounds tend to be stretched or elongated parallel to the

0:49:27.200 --> 0:49:30.560
<v Speaker 3>direction that this water from the flood would have been flowing.

0:49:31.400 --> 0:49:33.480
<v Speaker 3>Though from what I'm reading, I think it's possible that

0:49:33.600 --> 0:49:37.279
<v Speaker 3>a glacial flood like this could have shaped mounds, even

0:49:37.320 --> 0:49:40.000
<v Speaker 3>if it wasn't the thing that originally formed them.

0:49:40.400 --> 0:49:41.800
<v Speaker 2>Okay, one more.

0:49:41.719 --> 0:49:45.440
<v Speaker 3>Idea, this is the earthquake hypothesis. This one appeared more recently.

0:49:45.560 --> 0:49:48.040
<v Speaker 3>It was put forward by a geologist named Andrew Berg

0:49:48.160 --> 0:49:51.880
<v Speaker 3>in nineteen ninety and to illustrate the idea behind it,

0:49:52.400 --> 0:49:56.120
<v Speaker 3>you can start with an experiment. If you take a

0:49:56.239 --> 0:49:59.560
<v Speaker 3>flat surface like a table or a drumhead or anything

0:49:59.680 --> 0:50:02.759
<v Speaker 3>like that, and you spread out an even layer of

0:50:03.040 --> 0:50:06.799
<v Speaker 3>fine silt or sand on top of that surface, then

0:50:06.880 --> 0:50:09.520
<v Speaker 3>you make the surface vibrate. So maybe you hit the

0:50:09.760 --> 0:50:14.040
<v Speaker 3>table or the drumhead repeatedly with a mallet. Causing the

0:50:14.160 --> 0:50:18.600
<v Speaker 3>surface to vibrate, will tend to make loose sediment lying

0:50:18.719 --> 0:50:23.160
<v Speaker 3>on top of it arrange itself into interesting geometrical patterns.

0:50:23.880 --> 0:50:25.759
<v Speaker 3>You might have seen something like this if you've ever

0:50:25.840 --> 0:50:29.440
<v Speaker 3>watched these demonstrations of like a sound from a speaker

0:50:30.000 --> 0:50:32.880
<v Speaker 3>acting on sand on a flat surface, Like you can

0:50:32.920 --> 0:50:37.239
<v Speaker 3>play different frequency tones through a loudspeaker over a drumhead

0:50:37.360 --> 0:50:40.680
<v Speaker 3>like surface, and it will make the sand sort itself

0:50:40.760 --> 0:50:44.800
<v Speaker 3>into these fascinating geometrical patterns driven by the sound waves.

0:50:45.640 --> 0:50:48.239
<v Speaker 3>These arrangements tend to be caused by the interactions the

0:50:48.320 --> 0:50:51.160
<v Speaker 3>kind of resonance of different waves going back and forth,

0:50:51.280 --> 0:50:55.200
<v Speaker 3>and you get these places where the waves, you know,

0:50:55.320 --> 0:50:58.240
<v Speaker 3>they sort of line up and they form these standing peaks,

0:50:58.360 --> 0:51:02.120
<v Speaker 3>and then also place is where they cancel each other

0:51:02.239 --> 0:51:07.080
<v Speaker 3>out and create these valleys. Anyway, Berg proposed that earthquakes

0:51:07.239 --> 0:51:10.200
<v Speaker 3>in the past had caused a similar thing to happen

0:51:10.600 --> 0:51:15.160
<v Speaker 3>with loose soil on top of the Mima Prairie. So

0:51:15.600 --> 0:51:18.879
<v Speaker 3>interesting idea there too, And ultimately, from what I can tell,

0:51:19.000 --> 0:51:21.600
<v Speaker 3>this really is still genuinely a mystery.

0:51:21.880 --> 0:51:22.680
<v Speaker 4>It is not solved.

0:51:22.760 --> 0:51:26.600
<v Speaker 3>Each hypothesis I think has its own defenders and advocates,

0:51:27.440 --> 0:51:31.000
<v Speaker 3>but there is not agreement within the scientific community or

0:51:31.080 --> 0:51:35.279
<v Speaker 3>the communities involved that like which one is the best explanation.

0:51:35.880 --> 0:51:38.279
<v Speaker 3>So this made me curious, like, if you're out there

0:51:38.320 --> 0:51:40.960
<v Speaker 3>listening right now, you're a geologist or somebody with some

0:51:41.120 --> 0:51:43.479
<v Speaker 3>other relevant expertise, and you want to write in about

0:51:43.520 --> 0:51:46.920
<v Speaker 3>which hypothesis seems strongest to you and why, please do

0:51:47.040 --> 0:51:49.480
<v Speaker 3>get in touch. Our email is contact at stuff to

0:51:49.520 --> 0:51:50.520
<v Speaker 3>Blow your Mind dot com.

0:51:51.120 --> 0:51:53.719
<v Speaker 2>You know, I was looking at this booklet you referenced earlier,

0:51:53.800 --> 0:51:56.719
<v Speaker 2>the one for students, and I really enjoyed that the

0:51:57.280 --> 0:52:01.960
<v Speaker 2>different hypotheses are presented by a talking gopher name Goodwin,

0:52:02.840 --> 0:52:06.000
<v Speaker 2>and good one is very very clear that these are

0:52:06.040 --> 0:52:09.080
<v Speaker 2>presented in no particular order of likelihood, so that you

0:52:09.200 --> 0:52:12.640
<v Speaker 2>can decide this is a very balanced gopher. And I

0:52:12.719 --> 0:52:16.040
<v Speaker 2>appreciate even though one of the ideas concerns gophers, and

0:52:16.200 --> 0:52:18.839
<v Speaker 2>you know, you would otherwise be led to think, well, good,

0:52:18.880 --> 0:52:21.440
<v Speaker 2>one's going to want to really push the the one

0:52:21.520 --> 0:52:25.479
<v Speaker 2>that champions his own species abilities. But no, he's calling

0:52:25.520 --> 0:52:26.319
<v Speaker 2>it right down the middle.

0:52:26.520 --> 0:52:27.880
<v Speaker 4>I was thinking that exact thing.

0:52:28.120 --> 0:52:30.360
<v Speaker 3>It's like, oh, we want to have a talking gopher,

0:52:30.600 --> 0:52:32.960
<v Speaker 3>but that's going to make it seem like the gopher

0:52:33.040 --> 0:52:35.000
<v Speaker 3>hypothesis is the real winner, and we.

0:52:35.040 --> 0:52:37.279
<v Speaker 4>Don't want to imply that. So we've got to say,

0:52:37.560 --> 0:52:39.920
<v Speaker 4>you know, we're not favoring any one of these.

0:52:40.360 --> 0:52:44.240
<v Speaker 2>But which one illustrates the easiest, which one potentially speaks

0:52:44.320 --> 0:52:47.880
<v Speaker 2>to children better? You know this is this is the

0:52:47.920 --> 0:52:50.800
<v Speaker 2>one to go in. So yeah, totally the right direction

0:52:50.920 --> 0:52:53.640
<v Speaker 2>for the booklet. Well, that's fascinating. Yet I was not

0:52:53.880 --> 0:52:57.080
<v Speaker 2>familiar with these these particular mounds. I've not traveled to

0:52:57.160 --> 0:53:00.080
<v Speaker 2>this part of the country before. But if I if

0:53:00.080 --> 0:53:01.399
<v Speaker 2>I make it out that way, I'll have to check

0:53:01.440 --> 0:53:01.839
<v Speaker 2>these out.

0:53:02.200 --> 0:53:02.359
<v Speaker 4>Well.

0:53:02.400 --> 0:53:06.200
<v Speaker 3>As I said, they're not only in southwestern Washington. There

0:53:06.239 --> 0:53:10.160
<v Speaker 3>are Mama like mounds actually in many places throughout North America,

0:53:10.360 --> 0:53:13.839
<v Speaker 3>and there are similar formations on other continents as well.

0:53:14.320 --> 0:53:17.080
<v Speaker 3>So you can look up maps of Mama like mounds,

0:53:17.160 --> 0:53:19.120
<v Speaker 3>you know. There there are places you can see them

0:53:19.160 --> 0:53:21.640
<v Speaker 3>all over different regions of the prairie. There's some like

0:53:21.760 --> 0:53:25.480
<v Speaker 3>in Texas and other places farther in the Northwest Prairie.

0:53:26.640 --> 0:53:29.440
<v Speaker 3>So yeah, there you can look for things like this

0:53:29.640 --> 0:53:30.600
<v Speaker 3>in lots of places.

0:53:31.320 --> 0:53:31.520
<v Speaker 2>Huh.

0:53:31.719 --> 0:53:31.880
<v Speaker 4>You know.

0:53:31.920 --> 0:53:35.280
<v Speaker 2>I just pulled up a map of where one finds

0:53:35.880 --> 0:53:40.480
<v Speaker 2>Mima mounds throughout North America, and there are there. They

0:53:40.520 --> 0:53:42.360
<v Speaker 2>are in place that you can find them in California.

0:53:42.360 --> 0:53:47.359
<v Speaker 2>You can find them in Arizona, various other states, including Arkansas, Louisiana.

0:53:47.880 --> 0:53:49.719
<v Speaker 2>So yeah, they're they're out there. I just need a

0:53:49.960 --> 0:53:52.920
<v Speaker 2>I need a I need to put them on the itinerary.

0:53:52.440 --> 0:53:55.359
<v Speaker 4>I guess. Yeah. I'd like to see some too. Yeah.

0:53:56.560 --> 0:53:59.080
<v Speaker 2>All right, Well, I think that's all for this episode

0:53:59.400 --> 0:54:02.520
<v Speaker 2>on Prayer. We're going to gohea and close out this

0:54:03.160 --> 0:54:05.279
<v Speaker 2>this episode, but we'd love to hear from everyone out

0:54:05.320 --> 0:54:08.840
<v Speaker 2>there again. Anything you have to contribute regarding these topics,

0:54:08.840 --> 0:54:14.280
<v Speaker 2>any field reports, be it mound based or prairie vibe based.

0:54:14.760 --> 0:54:16.520
<v Speaker 2>You know, certainly write in and we would love to

0:54:16.600 --> 0:54:19.399
<v Speaker 2>hear from you, and you know, we'd like to use

0:54:19.600 --> 0:54:22.480
<v Speaker 2>at least some of our listener mails in future listener

0:54:22.560 --> 0:54:25.080
<v Speaker 2>mail episodes of Stuff to Blow Your Mind. You generally

0:54:25.120 --> 0:54:27.439
<v Speaker 2>do about one of those a month, maybe sometimes two,

0:54:27.719 --> 0:54:30.600
<v Speaker 2>depending on how much, how much is coming in and

0:54:30.960 --> 0:54:33.160
<v Speaker 2>what sort of buffers they need to put into the schedule.

0:54:33.800 --> 0:54:35.759

0:54:43.320 --> 0:54:45.239
<v Speaker 2>aside most serious concerns to just talk about a weird

0:54:45.320 --> 0:54:47.000
<v Speaker 2>film on Weird House Cinema.
