I've chosen our January 3 00:00:06,040 --> 00:00:10,080 Speaker 2: twenty twenty three episode on the Mount Saint Helen's eruption. 4 00:00:10,600 --> 00:00:13,640 Speaker 2: It seems like just last year. It's a really good 5 00:00:13,640 --> 00:00:19,759 Speaker 2: episode that's packed with science, action, adventure, heroics, life and death, danger, 6 00:00:20,040 --> 00:00:22,840 Speaker 2: It's got it all. It's one of my favorite episodes, 7 00:00:23,079 --> 00:00:30,040 Speaker 2: so I hope you enjoy it as well. 8 00:00:30,080 --> 00:00:37,800 Speaker 3: Welcome to Stuff you should know, a production of iHeartRadio. 9 00:00:41,320 --> 00:00:42,680 Speaker 1: Hey, and welcome to the podcast. 10 00:00:42,720 --> 00:00:45,320 Speaker 2: I'm Josh, and there's Chuck and sitting in for Jerry 11 00:00:45,320 --> 00:00:49,480 Speaker 2: today is our great friend and co producer Dave Sea, 12 00:00:50,080 --> 00:00:55,000 Speaker 2: and the C stands for cool.

This is I mean, 25 00:01:28,720 --> 00:01:30,720 Speaker 3: this is so bread and butter stuff. You should know 26 00:01:31,480 --> 00:01:33,520 Speaker 3: it is. I don't know why it took us almost 27 00:01:33,560 --> 00:01:34,840 Speaker 3: sixteen years to get to it. 28 00:01:35,400 --> 00:01:37,840 Speaker 2: And none of that margarine stuff are low fat. It's 29 00:01:37,880 --> 00:01:41,679 Speaker 2: like full milk fat butter. Man bread and butter stuff. 30 00:01:41,680 --> 00:01:45,039 Speaker 2: You should know salted butter even you like salted huh. 31 00:01:45,240 --> 00:01:47,840 Speaker 2: It depends what you're using it for. I like just 32 00:01:47,960 --> 00:01:51,280 Speaker 2: plain unsalted butter, even on a bread and butter piece 33 00:01:51,320 --> 00:01:52,440 Speaker 2: of like bread with butter. 34 00:01:52,720 --> 00:01:55,560 Speaker 3: Yeah, mainly with like baking and cooking. It's like that's 35 00:01:55,560 --> 00:01:56,240 Speaker 3: when it matters. 36 00:01:56,640 --> 00:01:59,080 Speaker 1: Yeah, I gotcha. What's your brand? 37 00:02:00,280 --> 00:02:00,520 Speaker 3: Oh? 38 00:02:00,640 --> 00:02:00,920 Speaker 1: Boy? 39 00:02:00,960 --> 00:02:04,720 Speaker 3: It depends. I mean I love to get the heat 40 00:02:04,760 --> 00:02:06,280 Speaker 3: to be that guy, but I do love to get 41 00:02:06,320 --> 00:02:08,919 Speaker 3: the local butter when we go to our farmer's market 42 00:02:08,960 --> 00:02:10,240 Speaker 3: and get it from our CSA. 43 00:02:10,639 --> 00:02:11,359 Speaker 1: What's wrong with that? 44 00:02:11,760 --> 00:02:14,639 Speaker 3: Well, I don't know. Can't you say, park Ca? 45 00:02:14,639 --> 00:02:15,639 Speaker 1: Can you right? 46 00:02:15,680 --> 00:02:18,560 Speaker 2: You must be a social justice warrior you buy local butter. 47 00:02:18,720 --> 00:02:21,160 Speaker 3: I do you like that? What's the stuff? The Irish 48 00:02:21,160 --> 00:02:22,359 Speaker 3: butter in the grocery store? 49 00:02:22,880 --> 00:02:25,440 Speaker 1: That's my brand? Carry Gold? 50 00:02:25,520 --> 00:02:28,000 Speaker 3: Carry Gold. That's good too, Like I've. 51 00:02:28,000 --> 00:02:31,840 Speaker 2: I've researched it, like I've literally researched the butter because 52 00:02:31,880 --> 00:02:33,520 Speaker 2: I want to get the most bang for my buck, 53 00:02:33,800 --> 00:02:36,240 Speaker 2: and it is at the top of basically every list. 54 00:02:36,320 --> 00:02:38,840 Speaker 2: It's good of like any butter of any kind, it's 55 00:02:39,000 --> 00:02:40,120 Speaker 2: really really good butter. 56 00:02:40,280 --> 00:02:42,400 Speaker 3: Yeah, I totally agree. I love carry gold. I take 57 00:02:42,400 --> 00:02:43,120 Speaker 3: that stuff camping. 58 00:02:43,880 --> 00:02:45,640 Speaker 1: Yeah, I carried it around in my pocket. 59 00:02:46,680 --> 00:02:48,880 Speaker 3: Well, I like it. You can get a tub. It's 60 00:02:48,919 --> 00:02:51,040 Speaker 3: a smaller tub, but I do like a spreadable tub 61 00:02:51,080 --> 00:02:52,040 Speaker 3: as opposed to a stick. 62 00:02:52,560 --> 00:02:54,800 Speaker 2: I haven't seen the tub. We have a stick because 63 00:02:54,840 --> 00:02:57,040 Speaker 2: we have a cute little butter dish that. 64 00:02:56,919 --> 00:03:00,320 Speaker 1: We use, so we use the sticks. 65 00:03:00,800 --> 00:03:05,680 Speaker 2: So anyway, back to Mount Saint Helens the episode today. 66 00:03:06,160 --> 00:03:08,560 Speaker 2: I was four years old when this happened, so I 67 00:03:08,560 --> 00:03:11,200 Speaker 2: mean I didn't know what was going on, but I imagine 68 00:03:11,080 --> 00:03:12,800 Speaker 2: you were like, holy cow, this is one of the 69 00:03:12,800 --> 00:03:14,720 Speaker 2: most amazing things I've ever seen on my TV. 70 00:03:15,200 --> 00:03:18,320 Speaker 3: Yeah, I was nine, and I remember it being a 71 00:03:18,360 --> 00:03:21,480 Speaker 3: big deal. But it's funny when I was researching this 72 00:03:21,560 --> 00:03:24,840 Speaker 3: and then watching there's a really really great thing on 73 00:03:24,880 --> 00:03:26,880 Speaker 3: YouTube that I recommend that A and E put out 74 00:03:28,440 --> 00:03:30,480 Speaker 3: years ago. It had to be it was called minute 75 00:03:30,480 --> 00:03:35,920 Speaker 3: by minute colon. The eruption of Mount Saint Helen's really 76 00:03:35,960 --> 00:03:38,160 Speaker 3: gripping stuff. As A and E used to do. You know, 77 00:03:38,200 --> 00:03:40,440 Speaker 3: they probably still do that kind of stuff. But I 78 00:03:40,520 --> 00:03:43,360 Speaker 3: don't know all of the media around it. I was thinking, 79 00:03:43,440 --> 00:03:46,480 Speaker 3: like man, and I don't know if it was more 80 00:03:46,560 --> 00:03:49,440 Speaker 3: regional or if it truly was nationwide. But I remember 81 00:03:49,480 --> 00:03:53,320 Speaker 3: the eruption, but I didn't remember like the six weeks 82 00:03:53,400 --> 00:03:55,640 Speaker 3: leading up to it, which was a very big deal. 83 00:03:56,680 --> 00:03:59,760 Speaker 2: Yeah, although I think it was more of like a yeah, 84 00:04:00,200 --> 00:04:03,040 Speaker 2: regional thing for this the lead up. And then also 85 00:04:03,080 --> 00:04:07,800 Speaker 2: if you were a geologist, a volcanologists, a seismologist, anything 86 00:04:07,800 --> 00:04:11,080 Speaker 2: that had to do with volcanoes erupting or mountains, then 87 00:04:11,200 --> 00:04:12,880 Speaker 2: it would have been a big deal to you too. 88 00:04:12,880 --> 00:04:15,880 Speaker 2: And it definitely attracted them from far and wide. And 89 00:04:15,960 --> 00:04:20,679 Speaker 2: because there was so much warning and it was able 90 00:04:20,720 --> 00:04:23,240 Speaker 2: to buy it, I mean, Mount Saint Helens was able 91 00:04:23,240 --> 00:04:25,480 Speaker 2: to kind of draw to it like a magnet. All 92 00:04:25,520 --> 00:04:31,040 Speaker 2: of these amazingly well trained researchers. They were there when 93 00:04:31,080 --> 00:04:34,240 Speaker 2: it went off, and it's probably the most best documented 94 00:04:34,400 --> 00:04:36,320 Speaker 2: volcano in history because of that. 95 00:04:36,760 --> 00:04:39,080 Speaker 3: Yeah, I mean, because like you said, the Mount Saint 96 00:04:39,080 --> 00:04:42,000 Speaker 3: Helens is basically saying it's coming everyone. Would you like 97 00:04:42,040 --> 00:04:45,040 Speaker 3: to document this? Yeah, I'm telling you again it's coming, 98 00:04:46,040 --> 00:04:48,160 Speaker 3: and I'll show you in lots of different scary ways 99 00:04:48,200 --> 00:04:53,280 Speaker 3: that it's coming. And people left, people stayed, people came there, 100 00:04:53,600 --> 00:04:59,400 Speaker 3: people like tourists came to see this thing. So for sure, 101 00:05:00,040 --> 00:05:00,760 Speaker 3: let's get into it. 102 00:05:01,440 --> 00:05:05,880 Speaker 2: Okay, So just a real quick refresher, we've done volcanoes, 103 00:05:05,920 --> 00:05:08,360 Speaker 2: and I think we've done super volcanoes too, because that 104 00:05:08,440 --> 00:05:09,120 Speaker 2: sounds like us. 105 00:05:09,200 --> 00:05:14,560 Speaker 3: Yeah, twenty ten was volcanoes, twenty seventeen with super volcanoes. 106 00:05:14,960 --> 00:05:15,279 Speaker 1: Okay. 107 00:05:15,320 --> 00:05:17,400 Speaker 2: So we talked a lot about how volcanoes work in 108 00:05:17,440 --> 00:05:19,599 Speaker 2: those episodes, So if you want to know a lot 109 00:05:19,640 --> 00:05:22,240 Speaker 2: more in depth, go check those out. But just as 110 00:05:22,240 --> 00:05:25,279 Speaker 2: a refresher for the specific kind of volcano that mount 111 00:05:25,320 --> 00:05:30,080 Speaker 2: Saint Helens is. It's a stratovolcano, and it's created when 112 00:05:30,320 --> 00:05:35,200 Speaker 2: one younger plate is subducted under an older plate, and 113 00:05:35,240 --> 00:05:38,000 Speaker 2: as the younger plate goes down into the bowels of 114 00:05:38,040 --> 00:05:40,679 Speaker 2: the Earth, all of the rocket carries with it gets 115 00:05:40,680 --> 00:05:44,000 Speaker 2: heated up. Same with water too, and that stuff travels 116 00:05:44,080 --> 00:05:47,880 Speaker 2: upward because it's less dense than the surrounding mantle down below. 117 00:05:48,440 --> 00:05:50,640 Speaker 2: And as it gets closer and closer to the crust, 118 00:05:50,720 --> 00:05:52,760 Speaker 2: it wants to pop out of there. Yeah, but it 119 00:05:52,800 --> 00:05:55,880 Speaker 2: can't necessarily, sometimes it can, and when it can, it 120 00:05:56,040 --> 00:05:58,719 Speaker 2: just spews out all sorts of molten lava and that 121 00:05:58,800 --> 00:06:01,679 Speaker 2: builds the volcano in it kind of a cone shape, 122 00:06:01,720 --> 00:06:05,000 Speaker 2: which is what Mount Saint Helens was up until May eighteenth, 123 00:06:05,120 --> 00:06:05,799 Speaker 2: nineteen eighty. 124 00:06:06,040 --> 00:06:09,880 Speaker 3: Yeah. It's a part of the cascade arc arranged there 125 00:06:09,920 --> 00:06:13,200 Speaker 3: in the Pacific Northwest. And all of this happened and 126 00:06:13,600 --> 00:06:17,360 Speaker 3: you know, geologically speaking, pretty quickly. Yeah, it happened over 127 00:06:17,400 --> 00:06:19,360 Speaker 3: the course of about forty thousand years in the case 128 00:06:19,400 --> 00:06:24,080 Speaker 3: of Mount Saint Helens, which is pretty speedy. And Ed 129 00:06:24,160 --> 00:06:25,680 Speaker 3: helped us out with this when did a great job 130 00:06:25,680 --> 00:06:28,160 Speaker 3: on this article, and Ed points out that you know, 131 00:06:28,240 --> 00:06:30,520 Speaker 3: in the Pacific Northwest, that's why you see so many 132 00:06:31,160 --> 00:06:34,960 Speaker 3: you know, sort of coney mountains like that is because 133 00:06:35,000 --> 00:06:37,880 Speaker 3: of this cascade arc and how these mountains were formed, 134 00:06:38,400 --> 00:06:39,960 Speaker 3: you know, not too long ago. 135 00:06:39,960 --> 00:06:43,040 Speaker 1: Right, Yeah, forty thousand years ago, maybe less. 136 00:06:43,279 --> 00:06:45,279 Speaker 3: Forty thousand for Saint Helens, and I think the whole 137 00:06:45,400 --> 00:06:47,159 Speaker 3: arc is less than one hundred. 138 00:06:47,360 --> 00:06:51,480 Speaker 2: Right, So the whole thing that's driving Mount Saint Helens 139 00:06:51,520 --> 00:06:56,880 Speaker 2: and apparently also there's some other I guess volcanic mountains 140 00:06:56,920 --> 00:06:59,599 Speaker 2: in the area, like Adams. I think Mount Adams is 141 00:06:59,600 --> 00:07:02,960 Speaker 2: one is well. Yeah, there's a there's a magma chamber 142 00:07:03,000 --> 00:07:06,400 Speaker 2: somewhere under there, I think possibly miles and miles below 143 00:07:06,480 --> 00:07:09,560 Speaker 2: the surface. But under normal circumstances, like I said, when 144 00:07:09,600 --> 00:07:13,280 Speaker 2: a straddo volcanoes formed, the lava just kind of is 145 00:07:13,320 --> 00:07:16,160 Speaker 2: able to find cracks in the crust and like it's 146 00:07:16,440 --> 00:07:18,800 Speaker 2: released through there and it builds the mountain up slowly 147 00:07:18,840 --> 00:07:21,640 Speaker 2: and slowly. But if there's not a crack in the crust, 148 00:07:21,720 --> 00:07:25,480 Speaker 2: as in the case where Mount Saint Helens is, that 149 00:07:25,680 --> 00:07:28,120 Speaker 2: magma starts to back up. It hits the crust and 150 00:07:28,160 --> 00:07:30,840 Speaker 2: it starts to back up below and all of a 151 00:07:30,840 --> 00:07:34,120 Speaker 2: sudden you have a lot of stuff going on that 152 00:07:34,760 --> 00:07:39,119 Speaker 2: makes things go kaboom when the right set of circumstances happen. 153 00:07:39,640 --> 00:07:42,680 Speaker 3: Yeah, this is this is pretty notable. This magma chamber 154 00:07:42,960 --> 00:07:47,800 Speaker 3: is well is and was quite large, and like you said, 155 00:07:47,800 --> 00:07:49,800 Speaker 3: it's it's looking for a place to go. But if 156 00:07:49,840 --> 00:07:51,600 Speaker 3: it doesn't have a place to go, what will happen? 157 00:07:51,920 --> 00:07:53,360 Speaker 3: And as you'll see, this is what happened in the 158 00:07:53,360 --> 00:07:57,000 Speaker 3: case of Mount Saint Helens is it starts bulging, and 159 00:07:57,080 --> 00:08:00,720 Speaker 3: like the mountain, if you're a geologist, it's super exciting 160 00:08:00,760 --> 00:08:03,600 Speaker 3: to see this happen, even though it's very scary and dangerous. 161 00:08:03,600 --> 00:08:07,040 Speaker 3: But when a geologist sees an actual mountain start to 162 00:08:07,120 --> 00:08:10,480 Speaker 3: bulge out in a direction and we're talking, you know, 163 00:08:10,640 --> 00:08:12,720 Speaker 3: hundreds of feet of bulge over the course of a 164 00:08:12,720 --> 00:08:16,880 Speaker 3: pretty short period of time, then it's pretty like it's 165 00:08:16,920 --> 00:08:19,200 Speaker 3: a pretty notable thing. And that's exactly what was happening 166 00:08:19,560 --> 00:08:22,440 Speaker 3: in the case of the magma chamber there in Washington. 167 00:08:22,920 --> 00:08:25,480 Speaker 2: Yeah, like this pressure is building up so much it's 168 00:08:25,520 --> 00:08:29,440 Speaker 2: causing a boil on the mountain. The mountain grows a 169 00:08:29,480 --> 00:08:33,319 Speaker 2: goiter basically, and that's just full of pressure and magma 170 00:08:33,400 --> 00:08:35,840 Speaker 2: just waiting to go off. It doesn't always go off, 171 00:08:36,160 --> 00:08:39,560 Speaker 2: And in fact, Mount Saint Helen's had two bulges also 172 00:08:39,600 --> 00:08:45,199 Speaker 2: called cryptodomes, which is pretty awesome from previous volcanic eruptions. 173 00:08:45,320 --> 00:08:48,840 Speaker 2: One was called Goat Rocks bulge and then the other 174 00:08:48,880 --> 00:08:52,120 Speaker 2: one was called the Sugar Bowl bulge, and they just 175 00:08:52,679 --> 00:08:56,040 Speaker 2: never like the magma found its way out other ways, 176 00:08:56,400 --> 00:08:58,800 Speaker 2: but the bulge was left. This is a new bulge, 177 00:08:58,800 --> 00:09:00,880 Speaker 2: and like you said, it was growing I think about 178 00:09:00,920 --> 00:09:04,280 Speaker 2: six feet a day. Every day it kept growing another 179 00:09:04,360 --> 00:09:07,960 Speaker 2: six feet, which is really fast for a mountain to grow. 180 00:09:08,800 --> 00:09:11,319 Speaker 2: And that was one of the big signs initially that 181 00:09:11,800 --> 00:09:14,720 Speaker 2: something was going on. And one more thing before we 182 00:09:14,720 --> 00:09:18,160 Speaker 2: started to get into Mount Saint Helens itself, Chuck, I 183 00:09:18,160 --> 00:09:21,240 Speaker 2: think we need to say, like Mount Saint Helens was big. 184 00:09:21,520 --> 00:09:24,160 Speaker 2: It was a big eruption, but it was not the 185 00:09:24,200 --> 00:09:27,440 Speaker 2: biggest eruption Saint Helens has ever had, And apparently the 186 00:09:27,440 --> 00:09:30,400 Speaker 2: biggest eruption it's ever had came just about four thousand 187 00:09:30,480 --> 00:09:36,160 Speaker 2: years ago, which is within traditional like folk tale memory. 188 00:09:36,920 --> 00:09:39,800 Speaker 3: Yeah. I mean it had been an active volcano for 189 00:09:39,800 --> 00:09:45,840 Speaker 3: forty thousand years, but the big one before nineteen eighty was. Yeah, 190 00:09:45,880 --> 00:09:47,160 Speaker 3: like you said, for I was trying to look at 191 00:09:47,160 --> 00:09:49,800 Speaker 3: a specific year, but let's just say four thousand years ago. Yeah, 192 00:09:49,840 --> 00:09:52,440 Speaker 3: because once you get back that far, you know who cares? 193 00:09:52,440 --> 00:09:56,160 Speaker 3: Who cares? But it became, like you said, part of folklore. 194 00:09:56,480 --> 00:10:01,360 Speaker 3: The indigenous people there, especially the puyall Up people, called 195 00:10:01,360 --> 00:10:06,880 Speaker 3: the mountain Lewittowit, and there was a LeWitt Brewing company, 196 00:10:07,160 --> 00:10:09,440 Speaker 3: so I wanted to shout them out. This is one 197 00:10:09,480 --> 00:10:14,360 Speaker 3: of those things where I thought, I wonder why, because 198 00:10:14,400 --> 00:10:16,760 Speaker 3: there's been such a push to change names of things 199 00:10:17,280 --> 00:10:20,560 Speaker 3: over the past like decade or so, this is one 200 00:10:20,600 --> 00:10:24,800 Speaker 3: that was. It seems so like sort of egregious that 201 00:10:24,880 --> 00:10:27,720 Speaker 3: we should call it LeWitt and not Mount Saint Helen's. 202 00:10:28,440 --> 00:10:30,680 Speaker 3: That I'm pretty curious. I'm sure there's been pushes over 203 00:10:30,720 --> 00:10:32,480 Speaker 3: the years to get it changed. But the Europeans, of 204 00:10:32,520 --> 00:10:36,120 Speaker 3: course named it Mount Saint Helens in seventeen ninety two 205 00:10:37,400 --> 00:10:41,160 Speaker 3: after Captain George Vancouver. If that name rings a bell, 206 00:10:41,400 --> 00:10:44,360 Speaker 3: it should gave the name of it because of a 207 00:10:44,400 --> 00:10:50,320 Speaker 3: diplomat name. Allan fitz Herbert didn't call it fitz Herbert 208 00:10:50,320 --> 00:10:53,199 Speaker 3: Peak or anything like that because his noble title was 209 00:10:53,240 --> 00:10:56,400 Speaker 3: Baron Saint Helen's, thank god. But here's the rub is 210 00:10:56,440 --> 00:11:01,120 Speaker 3: that Allan fitz Herbert never even saw Mount Saint Helens, 211 00:11:01,200 --> 00:11:04,520 Speaker 3: the mountain named after him. So like, I don't know, 212 00:11:04,640 --> 00:11:08,400 Speaker 3: maybe maybe let's call this one LEWITTT Yeah, I think 213 00:11:08,480 --> 00:11:10,679 Speaker 3: that's a great idea actually, And the reason they call 214 00:11:10,760 --> 00:11:14,800 Speaker 3: it LeWitt that was she was named after a like 215 00:11:14,880 --> 00:11:20,280 Speaker 3: a famous volcanic fire tender woman and Lewett and a 216 00:11:20,320 --> 00:11:22,280 Speaker 3: couple of other men who fell in love with her 217 00:11:22,640 --> 00:11:27,360 Speaker 3: and fought for her became LeWitt, became Mount Saint Helens 218 00:11:27,440 --> 00:11:28,800 Speaker 3: or Lewett, if you want to call it that. 219 00:11:29,200 --> 00:11:31,800 Speaker 2: And then the other the other men who were fighting 220 00:11:31,880 --> 00:11:35,240 Speaker 2: for became Mount Hood and Mount Adams. They were smited 221 00:11:35,280 --> 00:11:38,439 Speaker 2: by the Creator God and turned into mountains for fighting. 222 00:11:39,640 --> 00:11:41,640 Speaker 2: And there's legends not just from the puyol Up but 223 00:11:41,720 --> 00:11:45,920 Speaker 2: other indigenous tribes around the area that something really big happened. 224 00:11:45,920 --> 00:11:48,200 Speaker 2: And it looks like what it is is a geo myth, 225 00:11:48,240 --> 00:11:50,560 Speaker 2: which we've talked about before. And I think the Great 226 00:11:50,559 --> 00:11:53,880 Speaker 2: Floods episode that has been handed down generation after generation 227 00:11:54,000 --> 00:11:59,000 Speaker 2: that describes this enormous eruption four thousand years ago pretty 228 00:11:59,000 --> 00:12:01,439 Speaker 2: good stuff, Yeah, for sure. And it was a big 229 00:12:01,559 --> 00:12:03,880 Speaker 2: eruption too. There's just one other thing. There is a 230 00:12:04,080 --> 00:12:08,120 Speaker 2: layer of tephra of basically volcanic ash and debris and 231 00:12:08,160 --> 00:12:12,240 Speaker 2: stuff that is so thick and so wide it goes 232 00:12:12,320 --> 00:12:16,280 Speaker 2: up into British Columbia and sixty two miles away from 233 00:12:16,320 --> 00:12:20,280 Speaker 2: Mount Saint Helen it's still twenty inches thick, almost two 234 00:12:20,320 --> 00:12:23,199 Speaker 2: feet thick of ash sixty two miles away. That's how 235 00:12:23,200 --> 00:12:26,559 Speaker 2: big that four thousand year ago eruption was that's huge. 236 00:12:26,640 --> 00:12:30,400 Speaker 3: And all this to say that Mount Saint Helen's, which 237 00:12:30,440 --> 00:12:32,000 Speaker 3: has an s by the way, did you know that? 238 00:12:33,600 --> 00:12:34,440 Speaker 1: Yeah? I did. 239 00:12:34,480 --> 00:12:35,880 Speaker 3: You keep saying, Helen. I just wondered. 240 00:12:36,600 --> 00:12:39,360 Speaker 2: I'm being short. I don't want to take up too 241 00:12:39,400 --> 00:12:41,240 Speaker 2: much time talking about certainly. 242 00:12:43,080 --> 00:12:43,600 Speaker 1: That's good. 243 00:12:44,320 --> 00:12:46,240 Speaker 3: That reminds me of the guy in college who fell 244 00:12:46,280 --> 00:12:49,040 Speaker 3: on the sidewalk and his books splayed out and then 245 00:12:49,080 --> 00:12:50,280 Speaker 3: he acted like he was reading. 246 00:12:50,880 --> 00:12:53,800 Speaker 1: Yeah, I love that story. I forgot about him. 247 00:12:54,400 --> 00:12:56,720 Speaker 3: All this to say is that Mount Saint Helen's had been, 248 00:12:57,040 --> 00:12:59,760 Speaker 3: you know, active, had a long history of activity. So 249 00:13:00,000 --> 00:13:02,840 Speaker 3: it's not like anyone ever thought, well, that thing is 250 00:13:02,880 --> 00:13:04,400 Speaker 3: done and it's never going to happen again. 251 00:13:04,960 --> 00:13:05,960 Speaker 1: No, definitely not. 252 00:13:06,600 --> 00:13:09,080 Speaker 2: Because also in the nineteenth century there was a lot 253 00:13:09,120 --> 00:13:12,199 Speaker 2: of eruptions too. There's a painting by a Canadian artist 254 00:13:12,240 --> 00:13:16,600 Speaker 2: named Paul Caine who painted an eighteen forty seven eruption. So, 255 00:13:16,800 --> 00:13:20,679 Speaker 2: I mean, starting in the nineteenth century, Mount Saint Helen's 256 00:13:21,520 --> 00:13:27,360 Speaker 2: was documented pretty clearly scientifically too, as being an eruptive volcano, 257 00:13:27,559 --> 00:13:28,840 Speaker 2: a disruptive volcano. 258 00:13:28,880 --> 00:13:29,960 Speaker 1: You can almost say. 259 00:13:30,520 --> 00:13:33,520 Speaker 3: All right, shall we take a break. Yeah, it's a 260 00:13:33,559 --> 00:13:36,080 Speaker 3: nice prelude, I think so too. All right, we'll be 261 00:13:36,080 --> 00:13:40,360 Speaker 3: back right after this, softy. 262 00:13:39,760 --> 00:13:44,160 Speaker 1: Josh so. 263 00:14:02,200 --> 00:14:04,600 Speaker 3: Okay. So we got a nice background on Mount Saint Helens. 264 00:14:04,720 --> 00:14:07,800 Speaker 3: It had been very active for about or on and 265 00:14:07,840 --> 00:14:12,079 Speaker 3: off active for forty thousand years, including I believe the 266 00:14:12,160 --> 00:14:15,680 Speaker 3: last sort of big one was in eighteen fifty seven. 267 00:14:17,160 --> 00:14:19,480 Speaker 3: Not too long after that, in nineteen oh eight, about 268 00:14:19,480 --> 00:14:23,520 Speaker 3: a million acres of land became part of Columbia National Forest, 269 00:14:23,600 --> 00:14:27,760 Speaker 3: which was hence renamed Gifford Pinchhot or Pinchot. I never 270 00:14:27,840 --> 00:14:30,920 Speaker 3: know how to say that the Bronson Pinchot National Forest 271 00:14:31,280 --> 00:14:33,280 Speaker 3: National Forest, and that was in nineteen forty nine, and 272 00:14:33,720 --> 00:14:38,280 Speaker 3: Mount Saint Helens is inside that National Forest. All this 273 00:14:38,840 --> 00:14:40,480 Speaker 3: is sort of a long way of saying it wasn't 274 00:14:40,520 --> 00:14:44,200 Speaker 3: like super populated. It didn't have wasn't surrounded by neighborhoods 275 00:14:44,200 --> 00:14:47,560 Speaker 3: and suburbs and stuff like that. But there was something 276 00:14:48,000 --> 00:14:51,200 Speaker 3: or is still something called Spirit Lake there near the 277 00:14:51,200 --> 00:14:54,320 Speaker 3: base of the mountain, which is they have like youth 278 00:14:54,400 --> 00:14:57,880 Speaker 3: camps there, People had cabins here and there. There were 279 00:14:58,840 --> 00:15:02,360 Speaker 3: recreational activities that all over the place. So it's not 280 00:15:02,400 --> 00:15:05,840 Speaker 3: like no one was there, but it wasn't heavily populated. 281 00:15:05,880 --> 00:15:10,280 Speaker 2: Right well put, so the whole thing starts. Actually even 282 00:15:10,320 --> 00:15:12,800 Speaker 2: before the whole thing started, and I saw in nineteen 283 00:15:12,840 --> 00:15:17,440 Speaker 2: seventy five the two volcanologists published a paper saying that 284 00:15:17,600 --> 00:15:20,040 Speaker 2: it was very likely Mount Saint Helens was going to 285 00:15:20,200 --> 00:15:22,920 Speaker 2: erupt in the twentieth century at some point, like a 286 00:15:22,960 --> 00:15:23,360 Speaker 2: big one. 287 00:15:23,480 --> 00:15:24,400 Speaker 3: Yeah. 288 00:15:24,440 --> 00:15:27,440 Speaker 2: And five years later, on March twentieth, nineteen eighty, the 289 00:15:27,480 --> 00:15:31,320 Speaker 2: whole thing was kicked off by a four point zero earthquake, 290 00:15:31,320 --> 00:15:33,640 Speaker 2: which is nothing to sneeze at, and it was at 291 00:15:33,680 --> 00:15:36,000 Speaker 2: the mountain, Like this earthquake took place at the mountain, 292 00:15:36,400 --> 00:15:39,320 Speaker 2: and all of a sudden, within five days there were 293 00:15:39,440 --> 00:15:43,560 Speaker 2: quake storms. There was twenty four quakes of four point 294 00:15:43,640 --> 00:15:47,240 Speaker 2: zero or greater within eight hours. Oh man, when a 295 00:15:47,360 --> 00:15:51,440 Speaker 2: volcano starts doing that and you're detecting it, that's when 296 00:15:51,520 --> 00:15:53,840 Speaker 2: the geologists come running from far and wide. 297 00:15:54,160 --> 00:15:56,880 Speaker 3: Yeah. So they you know, the word gets out, and 298 00:15:56,960 --> 00:15:58,840 Speaker 3: they did cone running from far and wide, and they 299 00:15:59,040 --> 00:16:03,200 Speaker 3: you know, set up camp there at various places. Other 300 00:16:03,560 --> 00:16:07,120 Speaker 3: just sort of as I learned from watching this an 301 00:16:07,120 --> 00:16:11,160 Speaker 3: e special, that there are like volcano chasers even that 302 00:16:12,040 --> 00:16:14,440 Speaker 3: they hear about this stuff. They're fascinated by it. I 303 00:16:14,440 --> 00:16:18,720 Speaker 3: guess it's just sort of amateur geo enthusiasts. And people 304 00:16:18,760 --> 00:16:21,160 Speaker 3: started kind of coming in there because they got wind 305 00:16:21,240 --> 00:16:25,080 Speaker 3: that something may be brewing at Mount Saint Helen's including 306 00:16:25,160 --> 00:16:26,960 Speaker 3: and this is you know, there are all kinds of 307 00:16:26,960 --> 00:16:30,040 Speaker 3: people we could feature story wise, but one gentleman we 308 00:16:30,040 --> 00:16:32,720 Speaker 3: are going to feature. His name was David Johnston, and 309 00:16:32,760 --> 00:16:36,920 Speaker 3: he was a volcanologist at the USGS, the United States 310 00:16:36,920 --> 00:16:40,720 Speaker 3: Geographical Survey, and he was one of the There were 311 00:16:40,720 --> 00:16:42,720 Speaker 3: some great interviews with him in this A and E special. 312 00:16:42,760 --> 00:16:46,240 Speaker 3: He was very young guy, super excited to be there, 313 00:16:46,360 --> 00:16:48,560 Speaker 3: and he was one of the ones kind of sounding 314 00:16:48,600 --> 00:16:50,960 Speaker 3: the alarm along with his partner and this guy named 315 00:16:50,960 --> 00:16:55,000 Speaker 3: Don Swanson about hey, like you know, the s is 316 00:16:55,040 --> 00:16:58,680 Speaker 3: getting real here everybody, and it looks like thing like 317 00:16:58,680 --> 00:16:59,920 Speaker 3: people need to start leaving. 318 00:17:01,000 --> 00:17:03,960 Speaker 2: Yeah, Like the thing is is there were the people 319 00:17:03,960 --> 00:17:05,880 Speaker 2: who did live on the mountain were not the kind 320 00:17:05,880 --> 00:17:09,080 Speaker 2: of folk who listened to like you know, the governmental 321 00:17:09,119 --> 00:17:12,520 Speaker 2: net and college boys or the government to be told 322 00:17:12,600 --> 00:17:16,280 Speaker 2: like leave your home. And then also there was those 323 00:17:16,400 --> 00:17:19,200 Speaker 2: youth groups that were like you're going to ruin our week. 324 00:17:19,280 --> 00:17:26,320 Speaker 2: At Spirit Lake, there was also Weyerhaeuser exactly, it's like 325 00:17:26,400 --> 00:17:30,000 Speaker 2: a roller rink over there. And then there was Weyerhauser 326 00:17:30,000 --> 00:17:32,400 Speaker 2: who had a contract to be able to log on 327 00:17:32,560 --> 00:17:35,359 Speaker 2: the on the mountain. They definitely didn't want to have 328 00:17:35,400 --> 00:17:37,760 Speaker 2: to shut down operations. So there's a lot of pressure, 329 00:17:38,320 --> 00:17:40,560 Speaker 2: a surprising amount of pressure, you know, more than you 330 00:17:40,560 --> 00:17:43,840 Speaker 2: would think, to keep the mountain open. And David Johnston 331 00:17:44,080 --> 00:17:46,679 Speaker 2: and Don Swanson and some of the other colleagues were like, 332 00:17:47,160 --> 00:17:49,800 Speaker 2: you really can't do this, and they managed to convince 333 00:17:49,880 --> 00:17:52,480 Speaker 2: the governor of Washington that it was the right move. 334 00:17:52,720 --> 00:17:55,600 Speaker 2: And then later on, as we'll see, there was even 335 00:17:55,640 --> 00:17:58,720 Speaker 2: more pressure to reopen because things didn't go as fast 336 00:17:58,760 --> 00:18:02,000 Speaker 2: as everyone thought, and they managed to push that back 337 00:18:02,040 --> 00:18:04,960 Speaker 2: as well, and as a result, David Johnston is frequently 338 00:18:05,000 --> 00:18:08,800 Speaker 2: credited for saving thousands of lives. Yeah, potentially, which is 339 00:18:08,840 --> 00:18:11,080 Speaker 2: pretty cool. I mean, and everything I've seen about him, 340 00:18:11,119 --> 00:18:15,760 Speaker 2: he was a genuinely great person and also like a 341 00:18:15,800 --> 00:18:18,120 Speaker 2: really great pioneer in volcanology too. 342 00:18:18,320 --> 00:18:21,359 Speaker 3: Yeah. Absolutely, Yeah. They did eventually set up what they 343 00:18:21,400 --> 00:18:25,080 Speaker 3: called a red zone, and a lot of people did evacuate. 344 00:18:25,680 --> 00:18:29,520 Speaker 3: There were some notable people who didn't. Certainly, we need 345 00:18:29,560 --> 00:18:34,040 Speaker 3: to mention Harry Truman obviously not the president, but he 346 00:18:34,200 --> 00:18:37,080 Speaker 3: was this old codger who ran the lodge there, and 347 00:18:37,640 --> 00:18:40,879 Speaker 3: he became a folk hero because he famously thumbed his 348 00:18:40,960 --> 00:18:44,280 Speaker 3: nose and stayed and said, you know, I'm a part 349 00:18:44,320 --> 00:18:46,480 Speaker 3: of this place. It's a part of me. If the 350 00:18:46,520 --> 00:18:50,280 Speaker 3: mountain goes, I'm going to go with it. Art Carney 351 00:18:50,280 --> 00:18:53,480 Speaker 3: played him in the movie version. He got a lot 352 00:18:53,600 --> 00:18:58,879 Speaker 3: of media attention along with his sixteen cats, which is 353 00:18:58,880 --> 00:19:02,480 Speaker 3: the only part of the story. Like, hey, man, I'm 354 00:19:02,480 --> 00:19:04,719 Speaker 3: all for people evacuating and keep people safe, but I'm 355 00:19:04,760 --> 00:19:09,280 Speaker 3: also like some old old mountain man wants to stay 356 00:19:09,359 --> 00:19:12,000 Speaker 3: up there and go go down with a volcano. Like, yeah, 357 00:19:12,000 --> 00:19:15,440 Speaker 3: that's his right, but send the cats away. Don't say 358 00:19:15,560 --> 00:19:18,639 Speaker 3: like I'm gonna go down and kill these sixteen cats 359 00:19:18,720 --> 00:19:19,520 Speaker 3: at the same time. 360 00:19:20,200 --> 00:19:22,520 Speaker 2: Yeah, it's kind of like being buried in like you know, 361 00:19:22,760 --> 00:19:25,399 Speaker 2: medieval times and having your live horse buried with you. 362 00:19:25,680 --> 00:19:27,199 Speaker 3: Yeah. I just I don't know. Man. Once I heard 363 00:19:27,240 --> 00:19:29,679 Speaker 3: about the cats, because I was all into this guy, right, 364 00:19:29,720 --> 00:19:31,840 Speaker 3: and then I heard about the cats, I was like, oh, dude, 365 00:19:31,880 --> 00:19:33,600 Speaker 3: you should have at least sent the cats away. 366 00:19:34,119 --> 00:19:44,560 Speaker 2: Yeah, no way, not a lodge codure. So Harry Truman 367 00:19:44,600 --> 00:19:46,680 Speaker 2: will come back in. This is Harry ar Truman, by 368 00:19:46,680 --> 00:19:49,879 Speaker 2: the way, everybody said his middle initial to differentiate him. 369 00:19:50,240 --> 00:19:51,359 Speaker 1: He'll come back in later. 370 00:19:51,920 --> 00:19:54,879 Speaker 2: But so the last thing that we happened on the 371 00:19:54,920 --> 00:19:58,280 Speaker 2: mountain March twenty fifth, in eight hours, there's twenty four 372 00:19:58,480 --> 00:20:01,600 Speaker 2: four point zero or greater magnitude earthquakes, and that brought 373 00:20:01,600 --> 00:20:06,000 Speaker 2: everybody running. This whole thing was so perfectly planned that 374 00:20:06,119 --> 00:20:10,120 Speaker 2: on the day of the eruption there was the mineral 375 00:20:10,200 --> 00:20:13,600 Speaker 2: and gem show in Yakima, like I think, less than 376 00:20:13,640 --> 00:20:16,560 Speaker 2: one hundred miles away from Mount Saint Helens. So anybody 377 00:20:16,600 --> 00:20:20,399 Speaker 2: who had anything to do with geology just happened to 378 00:20:20,440 --> 00:20:24,240 Speaker 2: be in the area or was purposefully in the area. 379 00:20:24,280 --> 00:20:26,800 Speaker 2: And then on March twenty seventh, it's just getting more 380 00:20:26,840 --> 00:20:30,200 Speaker 2: and more and more. There was an actual eruption, right. 381 00:20:30,640 --> 00:20:33,560 Speaker 3: Yeah, So this was I mean, compared to what eventually 382 00:20:33,600 --> 00:20:36,400 Speaker 3: ended up happening, you could call this sort of mini eruption. 383 00:20:37,400 --> 00:20:40,960 Speaker 3: Even though it sent it made a big boom. Apparently 384 00:20:41,000 --> 00:20:43,800 Speaker 3: it was a pretty cloudy day so it wasn't super visible, 385 00:20:43,800 --> 00:20:47,480 Speaker 3: but the ashcolumn went up sixty five hundred feet into 386 00:20:47,520 --> 00:20:47,840 Speaker 3: the air. 387 00:20:48,359 --> 00:20:49,520 Speaker 1: It's nothing to sneeze it. 388 00:20:49,600 --> 00:20:52,680 Speaker 3: And a new crater formed at the summit, which grew 389 00:20:52,680 --> 00:20:56,919 Speaker 3: to about sixteen hundred feet wide, so it was a 390 00:20:56,920 --> 00:20:58,920 Speaker 3: major thing. There was another one on the twenty eighth, 391 00:20:59,280 --> 00:21:02,919 Speaker 3: again throwing ash into the air. And this is like 392 00:21:03,160 --> 00:21:07,359 Speaker 3: basically from that point through the big one in mid May, 393 00:21:08,040 --> 00:21:14,879 Speaker 3: it was just constant warning, constant upheople, mud slides, avalanches, 394 00:21:15,400 --> 00:21:19,120 Speaker 3: craters growing, and like the mountain is saying, like it's 395 00:21:19,200 --> 00:21:21,320 Speaker 3: going to happen people, This is not a false alarm 396 00:21:22,480 --> 00:21:25,640 Speaker 3: until things calm down. And that's what you were talking 397 00:21:25,640 --> 00:21:28,200 Speaker 3: about earlier, Like things kind of settled down. 398 00:21:28,119 --> 00:21:32,440 Speaker 1: On what was that like May around the fifteenth. 399 00:21:32,040 --> 00:21:34,479 Speaker 3: Yeah, around the fifteenth of May to where the people 400 00:21:35,320 --> 00:21:37,760 Speaker 3: got antsy that were evacuated and said, hey, listen, we 401 00:21:37,800 --> 00:21:40,239 Speaker 3: want to go back and check on our stuff. And 402 00:21:40,280 --> 00:21:42,440 Speaker 3: the governor eventually was like all right, I think it, 403 00:21:42,640 --> 00:21:44,400 Speaker 3: you know at the time, and I think Washington still 404 00:21:44,440 --> 00:21:47,399 Speaker 3: is a little bit of one of those like not 405 00:21:47,480 --> 00:21:50,520 Speaker 3: quite live free or die, but you know, like all right, listen, 406 00:21:50,560 --> 00:21:52,199 Speaker 3: these people pay taxes, they want to go back to 407 00:21:52,240 --> 00:21:55,240 Speaker 3: their homes, sign a waiver that you're not going to 408 00:21:55,320 --> 00:21:57,920 Speaker 3: sue us, and let them go back there. And that's 409 00:21:57,960 --> 00:21:58,440 Speaker 3: what they did. 410 00:21:59,000 --> 00:21:59,440 Speaker 1: They did. 411 00:21:59,600 --> 00:22:03,159 Speaker 2: There's footage of them signing waivers on the hood of 412 00:22:03,200 --> 00:22:05,880 Speaker 2: a car with some obvious state lawyer in a three 413 00:22:05,920 --> 00:22:09,600 Speaker 2: piece suit of canning people a pen being like signed here. 414 00:22:09,720 --> 00:22:12,920 Speaker 2: It's really hilarious, but they did. They started some people 415 00:22:12,960 --> 00:22:17,120 Speaker 2: started to trickle in, and that's actually why there were 416 00:22:18,119 --> 00:22:20,040 Speaker 2: you know, I think, And we ended up with fifty 417 00:22:20,200 --> 00:22:24,920 Speaker 2: seven casualties. Fifty seven people died and that was one 418 00:22:24,960 --> 00:22:27,720 Speaker 2: reason why it was actually that high. Could have could 419 00:22:27,720 --> 00:22:30,159 Speaker 2: have been less, but people were allowed to trickle back in. 420 00:22:30,440 --> 00:22:33,400 Speaker 2: They still kept like a perimeter, but I think it 421 00:22:33,480 --> 00:22:37,000 Speaker 2: was kind of porous. If you wanted to get through, 422 00:22:37,080 --> 00:22:39,520 Speaker 2: you could get through. And there are stories in that 423 00:22:39,640 --> 00:22:43,280 Speaker 2: minute by minute episode of People. There's this one backpacker 424 00:22:43,280 --> 00:22:46,720 Speaker 2: who is probably hilarious at parties because he makes like 425 00:22:46,760 --> 00:22:49,320 Speaker 2: a funny a funny voice for the police when the 426 00:22:49,320 --> 00:22:52,080 Speaker 2: police is talking, when he's recreating a conversation he had 427 00:22:53,200 --> 00:22:55,240 Speaker 2: he's stuck through with friends. There are a lot of 428 00:22:55,240 --> 00:22:57,360 Speaker 2: people on the mountain that otherwise might not have been 429 00:22:57,600 --> 00:22:59,840 Speaker 2: had they kept it closed. But they did open it 430 00:22:59,920 --> 00:23:02,320 Speaker 2: up a little bit, and it was because nothing had 431 00:23:02,359 --> 00:23:05,040 Speaker 2: happened for a little while and then about three days 432 00:23:05,119 --> 00:23:09,240 Speaker 2: later everything happened. You said, you said S was getting real. 433 00:23:09,440 --> 00:23:10,920 Speaker 2: This is when the s hit the fan. 434 00:23:12,160 --> 00:23:15,560 Speaker 3: Yeah, well, I mean just prior to this, I guess. 435 00:23:15,600 --> 00:23:17,679 Speaker 3: Let's back up one half second and let you know about, OK, 436 00:23:18,200 --> 00:23:20,760 Speaker 3: what happened when David Johnson and Don Swanson, they had 437 00:23:20,800 --> 00:23:24,720 Speaker 3: moved from their initial base at Coldwater one, which was 438 00:23:24,760 --> 00:23:30,160 Speaker 3: about I think eight or nine miles away, took their 439 00:23:30,280 --> 00:23:33,280 Speaker 3: second station, which was called cold Water two, which is 440 00:23:33,320 --> 00:23:36,800 Speaker 3: about five to six miles from the mountain, And notably 441 00:23:36,840 --> 00:23:38,600 Speaker 3: it was on the northeast side of the mountain, which 442 00:23:39,280 --> 00:23:42,199 Speaker 3: turned out to be the wrong spot to be. But 443 00:23:42,320 --> 00:23:45,120 Speaker 3: you know, these guys knew what was going on. They 444 00:23:45,440 --> 00:23:48,760 Speaker 3: know it's a dangerous job. And apparently they were swapping 445 00:23:49,560 --> 00:23:53,120 Speaker 3: taking shifts, and Don Swanson got the call from Johnston 446 00:23:53,200 --> 00:23:55,440 Speaker 3: and he said, hey, listen, I've got tonight and tomorrow 447 00:23:55,600 --> 00:23:58,000 Speaker 3: if you come and relieve me the next day. And 448 00:23:58,040 --> 00:24:01,879 Speaker 3: then on May eighteenth, nineteen eighty is when Johnston was 449 00:24:01,880 --> 00:24:03,879 Speaker 3: there when everything went boom. 450 00:24:04,119 --> 00:24:06,679 Speaker 2: Yeah, and I think there have been other colleagues and 451 00:24:06,800 --> 00:24:09,640 Speaker 2: grad students and everything around cold Water too, and Johnston 452 00:24:09,680 --> 00:24:11,959 Speaker 2: sent them away. He's like, this is outside the red zone. 453 00:24:12,080 --> 00:24:15,240 Speaker 2: It's still potentially dangerous. There's no reason for more than 454 00:24:15,320 --> 00:24:16,680 Speaker 2: just one of us to be here at a time. 455 00:24:16,720 --> 00:24:20,119 Speaker 2: So you guys go So at eight thirty two am 456 00:24:20,200 --> 00:24:24,960 Speaker 2: on May eighteenth, nineteen eighty, Mount Saint Helens like blew up. 457 00:24:25,480 --> 00:24:29,239 Speaker 2: And there's like a typical idea that people have of 458 00:24:29,480 --> 00:24:32,640 Speaker 2: a volcano going off, and most of the time it's 459 00:24:32,920 --> 00:24:35,919 Speaker 2: shooting like a huge thing of ash and magma straight 460 00:24:35,960 --> 00:24:38,959 Speaker 2: into the air from its top. Yeah, but that is 461 00:24:39,000 --> 00:24:41,760 Speaker 2: not what happened with Mount Saint Helens. Mount Saint Helens 462 00:24:41,800 --> 00:24:45,920 Speaker 2: was a very specific and unusual type of eruption because 463 00:24:45,960 --> 00:24:48,080 Speaker 2: it didn't go out of the top. It came out 464 00:24:48,160 --> 00:24:51,199 Speaker 2: of the side, and it came out in what was 465 00:24:51,720 --> 00:24:54,800 Speaker 2: known as a lateral blast eruption. Yeah. 466 00:24:54,920 --> 00:24:57,560 Speaker 3: So you know, like we said earlier, that pressure is 467 00:24:57,600 --> 00:25:01,479 Speaker 3: building up a lot under the surface. There's a lot 468 00:25:01,520 --> 00:25:04,679 Speaker 3: of moisture down there. Some of it was, like you mentioned, 469 00:25:04,680 --> 00:25:09,600 Speaker 3: from that initial plate subduction, that's called magmatic water. Some 470 00:25:09,640 --> 00:25:12,040 Speaker 3: of it is just regular old groundwater from rain and 471 00:25:12,080 --> 00:25:14,520 Speaker 3: snow and everything. Because it is the mountains, that's called 472 00:25:14,560 --> 00:25:18,040 Speaker 3: meteoric water, and all of that stuff is just heating up. 473 00:25:18,080 --> 00:25:21,199 Speaker 3: It's got pressure from below because it's heating, it's got 474 00:25:21,240 --> 00:25:23,680 Speaker 3: pressure from above because all of that weight of the 475 00:25:23,760 --> 00:25:26,600 Speaker 3: rock is just pushing it down, and all of this 476 00:25:26,760 --> 00:25:30,879 Speaker 3: magma is just like boiling under there. But I know 477 00:25:30,880 --> 00:25:32,879 Speaker 3: we talked about this before. I guess it was in 478 00:25:32,920 --> 00:25:36,159 Speaker 3: one of the volcano episodes. But it's not allowed to 479 00:25:36,160 --> 00:25:38,520 Speaker 3: turn to steam because there's no room for it. Like 480 00:25:38,840 --> 00:25:42,560 Speaker 3: steam is expansive and it can't expand So it's just 481 00:25:43,000 --> 00:25:48,840 Speaker 3: this superheated, beyond the boiling point level of liquid that's 482 00:25:48,920 --> 00:25:53,160 Speaker 3: just distributed all throughout the upper half and notably sort 483 00:25:53,160 --> 00:25:54,479 Speaker 3: of the north side of this mountain. 484 00:25:55,080 --> 00:25:58,120 Speaker 2: Yeah, and that created that bulge that kept growing by 485 00:25:58,119 --> 00:26:02,600 Speaker 2: about six feet a day. That was what the it 486 00:26:02,640 --> 00:26:05,800 Speaker 2: is because like it's as violent as as you can 487 00:26:05,840 --> 00:26:08,560 Speaker 2: imagine that a bulge, and something that could make a 488 00:26:08,560 --> 00:26:11,200 Speaker 2: bulge on the side of the mountain would be and 489 00:26:11,280 --> 00:26:17,080 Speaker 2: sound under other circumstances, a pliny an eruption where volcano 490 00:26:17,160 --> 00:26:19,479 Speaker 2: explodes out at the top, like you typically think of 491 00:26:20,200 --> 00:26:23,560 Speaker 2: that pressure that magma's going to basically force the top 492 00:26:23,600 --> 00:26:27,399 Speaker 2: of the mountain open and that's how it's going to explode. 493 00:26:27,840 --> 00:26:30,400 Speaker 2: This is not what happened with Mount Saint Helens that 494 00:26:30,880 --> 00:26:33,920 Speaker 2: kind of I guess the hump was on one side. 495 00:26:33,920 --> 00:26:36,399 Speaker 2: It was on the north flank, wasn't it. Yeah, so 496 00:26:36,440 --> 00:26:38,600 Speaker 2: it was on the north flank. And the thing that 497 00:26:38,680 --> 00:26:42,159 Speaker 2: kicked off Mount Saint Helens eruption wasn't the volcano. It 498 00:26:42,200 --> 00:26:47,240 Speaker 2: was actually an earthquake in the volcano, and that earthquake 499 00:26:47,359 --> 00:26:52,560 Speaker 2: caused the largest landslide and recorded history on Earth. More 500 00:26:52,600 --> 00:26:56,120 Speaker 2: than half of a square mile of Mount Saint Helen's 501 00:26:56,440 --> 00:27:00,880 Speaker 2: suddenly vanished away. It just suddenly dropped off the side 502 00:27:00,880 --> 00:27:02,159 Speaker 2: of the north side of the mountain. 503 00:27:02,560 --> 00:27:05,359 Speaker 3: Yeah. And it's like, you should really go check out 504 00:27:05,400 --> 00:27:08,480 Speaker 3: the footage of this stuff. It's some of the most amazing, 505 00:27:08,600 --> 00:27:13,320 Speaker 3: like natural geologic disaster footage I've ever seen, just to 506 00:27:13,359 --> 00:27:15,399 Speaker 3: see this mountain and then that you know, especially in 507 00:27:15,400 --> 00:27:19,639 Speaker 3: the ane thing, to see people interviewed describing like seeing 508 00:27:19,640 --> 00:27:22,800 Speaker 3: this with their eyeballs. It was just like it was 509 00:27:22,840 --> 00:27:26,280 Speaker 3: incomprehensible what they were witnessing, like a mountain that large 510 00:27:26,800 --> 00:27:29,959 Speaker 3: and part of it just going away immediately. 511 00:27:30,720 --> 00:27:30,880 Speaker 1: Yeah. 512 00:27:30,920 --> 00:27:33,040 Speaker 2: And one of the reasons they were able to witness it, 513 00:27:33,080 --> 00:27:35,800 Speaker 2: and we have such great documentations because at eight thirty 514 00:27:35,800 --> 00:27:39,600 Speaker 2: two am, a pair of geologists husband and wife geologists, 515 00:27:39,760 --> 00:27:42,520 Speaker 2: happened to be flying in a plane. Yeah, because they'd 516 00:27:42,600 --> 00:27:44,760 Speaker 2: hired a plane to go look at Mount Saint Helens 517 00:27:44,760 --> 00:27:47,399 Speaker 2: because they'd heard that, you know, it was there's some 518 00:27:47,440 --> 00:27:50,000 Speaker 2: stuff going on, and they happened to make one more 519 00:27:50,080 --> 00:27:53,600 Speaker 2: pass right as the mountain that earthquake dropped the side 520 00:27:53,600 --> 00:27:56,000 Speaker 2: of the mountain. They were like right above it in 521 00:27:56,040 --> 00:27:56,440 Speaker 2: a plane. 522 00:27:56,480 --> 00:27:57,119 Speaker 1: As a matter of. 523 00:27:57,119 --> 00:27:59,159 Speaker 3: Fact, Yeah, what's where's your quote? Should we read that? 524 00:27:59,680 --> 00:28:00,320 Speaker 1: Yeah? 525 00:28:00,359 --> 00:28:04,520 Speaker 3: This is Dorothy Dorothy Stoffel in twenty nineteen. She said, 526 00:28:04,560 --> 00:28:06,719 Speaker 3: the whole north half of the mountain that we were 527 00:28:06,720 --> 00:28:09,719 Speaker 3: flying just five hundred feet above, began churning, and a 528 00:28:09,760 --> 00:28:13,959 Speaker 3: mile long fracture shot across the mountain faster than our 529 00:28:14,000 --> 00:28:16,480 Speaker 3: minds could absorb. The north half of the mountain just 530 00:28:16,520 --> 00:28:19,000 Speaker 3: became like fluid and slid away. 531 00:28:19,960 --> 00:28:20,440 Speaker 1: Amazing. 532 00:28:20,480 --> 00:28:22,520 Speaker 2: I saw somebody else describe it as like a zipper 533 00:28:22,600 --> 00:28:23,840 Speaker 2: opening along the mountain. 534 00:28:24,960 --> 00:28:28,399 Speaker 3: Yeah. And you know, there were amateur photographers around for 535 00:28:28,440 --> 00:28:30,720 Speaker 3: some of this stuff. Some of these hikers like that 536 00:28:30,760 --> 00:28:34,240 Speaker 3: guy you mentioned that was telling the story and funny voices, 537 00:28:36,359 --> 00:28:40,120 Speaker 3: and volcano chasers like they got some like some one 538 00:28:40,120 --> 00:28:41,840 Speaker 3: guy got like twenty two pictures in a row, and 539 00:28:41,880 --> 00:28:43,840 Speaker 3: this is when it eventually blew. The other guy got 540 00:28:43,880 --> 00:28:48,800 Speaker 3: like six or eight pictures. There was a family camping 541 00:28:48,840 --> 00:28:51,440 Speaker 3: with their two young daughters. Oh Man, and that guy. 542 00:28:51,880 --> 00:28:54,640 Speaker 3: They were you know on the north side, you know, 543 00:28:54,680 --> 00:28:57,720 Speaker 3: well below it, but you know, within the range. And 544 00:28:57,800 --> 00:29:00,720 Speaker 3: he was like, you know, speaking to how it didn't 545 00:29:00,760 --> 00:29:02,440 Speaker 3: blow from the top, he said, it looked like somebody 546 00:29:02,480 --> 00:29:05,040 Speaker 3: shot a shotgun right out of the side of this 547 00:29:05,200 --> 00:29:09,040 Speaker 3: mountain pointed at us. So ash was raining down, but 548 00:29:09,120 --> 00:29:12,760 Speaker 3: it was raining like at people unless down from the 549 00:29:12,760 --> 00:29:14,440 Speaker 3: sky right exactly. 550 00:29:14,480 --> 00:29:16,160 Speaker 2: It wasn't going up and then coming back down. It 551 00:29:16,200 --> 00:29:19,000 Speaker 2: was coming straight at you if you were anywhere north 552 00:29:19,040 --> 00:29:19,640 Speaker 2: of the mountain. 553 00:29:19,720 --> 00:29:20,480 Speaker 3: Yeah. 554 00:29:20,520 --> 00:29:22,360 Speaker 2: And the reason why the north of the mountain was 555 00:29:22,360 --> 00:29:24,640 Speaker 2: so dangerous is because that's where that hump had been. 556 00:29:24,840 --> 00:29:28,000 Speaker 2: That's also where the earthquake moved a good portion of 557 00:29:28,040 --> 00:29:31,080 Speaker 2: the mountain, which meant that all that pressure that was 558 00:29:31,160 --> 00:29:36,520 Speaker 2: keeping that pressurized, superheated water from boiling under the mountain 559 00:29:36,840 --> 00:29:40,239 Speaker 2: was suddenly exposed. It was that pressure was gone, and 560 00:29:40,280 --> 00:29:45,400 Speaker 2: so all of that incredibly hot water flash heated into steam. 561 00:29:46,280 --> 00:29:49,040 Speaker 2: And when that happens, that expands, Like you said, The 562 00:29:49,080 --> 00:29:51,800 Speaker 2: reason that one of the reasons steam can't exist in 563 00:29:51,840 --> 00:29:56,400 Speaker 2: that situation is because it's too expansive. When it does 564 00:29:56,440 --> 00:30:01,040 Speaker 2: have the chance to expand, it does so within incredible force. 565 00:30:01,120 --> 00:30:03,040 Speaker 1: Yeah, and that's what happened. 566 00:30:03,080 --> 00:30:05,960 Speaker 2: That's why Mount Saint Helens blew out the side rather 567 00:30:06,000 --> 00:30:08,800 Speaker 2: than the top, because there had been a weakening and 568 00:30:08,840 --> 00:30:11,800 Speaker 2: the pressure that allowed all that to just blow out 569 00:30:12,240 --> 00:30:13,040 Speaker 2: and blow. 570 00:30:12,800 --> 00:30:13,400 Speaker 1: Out it did. 571 00:30:13,920 --> 00:30:17,240 Speaker 3: Yeah, I mean it was If you look at it, 572 00:30:17,240 --> 00:30:20,880 Speaker 3: it looks almost like a controlled demolition blast or something. 573 00:30:21,720 --> 00:30:24,000 Speaker 3: It definitely doesn't look like any kind of volcano blast 574 00:30:24,080 --> 00:30:26,840 Speaker 3: that you might think of in your head. It happened 575 00:30:26,880 --> 00:30:29,160 Speaker 3: kind of all at once, and it was a twenty 576 00:30:29,320 --> 00:30:33,640 Speaker 3: four mega ton blast, which I know everyone always tries 577 00:30:33,680 --> 00:30:37,080 Speaker 3: to compare it to like Hiroshima. It was sixteen hundred 578 00:30:37,160 --> 00:30:41,560 Speaker 3: times as powerful as the Hiroshima atomic bomb. 579 00:30:41,880 --> 00:30:44,080 Speaker 2: Good lord, but I mean that's what it would take 580 00:30:44,120 --> 00:30:48,600 Speaker 2: to move zero point six square cubic miles of mountain 581 00:30:48,640 --> 00:30:51,520 Speaker 2: all of a sudden too, you know. Yeah, and that 582 00:30:51,920 --> 00:30:55,600 Speaker 2: blast chuck, that twenty four mega ton blast. It was 583 00:30:55,680 --> 00:31:00,960 Speaker 2: described as like a fast moving cloud of heat in stones, 584 00:31:01,680 --> 00:31:04,520 Speaker 2: moving at some points pretty close to the mountain three 585 00:31:04,560 --> 00:31:07,920 Speaker 2: hundred miles an hour. He did to like six hundred 586 00:31:07,920 --> 00:31:10,240 Speaker 2: and sixty degrees fahrenheit. I think that's like three hundred 587 00:31:10,240 --> 00:31:15,760 Speaker 2: and eighty degrees celsius, just blowing northward away from the mountain, 588 00:31:16,240 --> 00:31:21,120 Speaker 2: and everything within eight miles of that of the mountain 589 00:31:21,560 --> 00:31:24,560 Speaker 2: was in that blast zone. And if you'll recall correctly, 590 00:31:24,920 --> 00:31:31,440 Speaker 2: David Johnston's cold Water to camp was within about five miles. 591 00:31:32,160 --> 00:31:35,280 Speaker 3: Yeah, he obviously didn't make it. They found I think 592 00:31:35,320 --> 00:31:37,640 Speaker 3: they found pieces of his trailer. Like a decade later. 593 00:31:38,560 --> 00:31:41,200 Speaker 3: He had time to send out one signal which was 594 00:31:42,240 --> 00:31:46,960 Speaker 3: over his radio Vancouver, Vancouver, this is it. The only 595 00:31:47,000 --> 00:31:50,120 Speaker 3: person to pick that up was a Ham radio operator nearby, 596 00:31:51,000 --> 00:31:55,800 Speaker 3: and they renamed that Aria Johnston Ridge in his honor. Obviously, 597 00:31:55,840 --> 00:32:00,280 Speaker 3: Harry Truman perished along with those sixteen cats, and he 598 00:32:00,440 --> 00:32:03,880 Speaker 3: was close enough to where I saw that. They said 599 00:32:03,880 --> 00:32:09,120 Speaker 3: that he and everything around him was basically instantly vaporized, 600 00:32:09,160 --> 00:32:11,640 Speaker 3: Like he wouldn't have felt anything. It would have happened 601 00:32:12,000 --> 00:32:15,080 Speaker 3: his death, and vaporization would have happened in like less 602 00:32:15,120 --> 00:32:15,680 Speaker 3: than a second. 603 00:32:16,160 --> 00:32:18,400 Speaker 2: Yeah, I have the impression the same thing happened to 604 00:32:18,480 --> 00:32:22,560 Speaker 2: David Johnston, and also that Ham radio operator who was 605 00:32:22,680 --> 00:32:27,760 Speaker 2: volunteering to kind of document it he documented David Johnston 606 00:32:28,480 --> 00:32:33,440 Speaker 2: getting covered up. He said, he said, gentlemen, the camper 607 00:32:33,520 --> 00:32:35,720 Speaker 2: and the car that's sitting over to the south of me. 608 00:32:35,800 --> 00:32:38,640 Speaker 2: He was talking about David Johnston is covered is going 609 00:32:38,680 --> 00:32:41,240 Speaker 2: to hit me too. And that was Jerry Martin, that 610 00:32:41,320 --> 00:32:44,520 Speaker 2: Ham radio operator and that was his last transmission. He 611 00:32:44,600 --> 00:32:49,160 Speaker 2: was vaporized as well. Essentially everything everything north of the 612 00:32:49,200 --> 00:32:55,160 Speaker 2: mountain within eight miles was just destroyed, just destroyed, like 613 00:32:55,520 --> 00:32:58,840 Speaker 2: entire one hundred foot trees that were like ten twelve 614 00:32:58,920 --> 00:33:03,240 Speaker 2: feet in diameter just completely flatten and also denuded. 615 00:33:02,800 --> 00:33:04,600 Speaker 1: Of any bark on the way as well. 616 00:33:05,520 --> 00:33:10,239 Speaker 2: And this was just a blast that the landslide that 617 00:33:10,360 --> 00:33:14,640 Speaker 2: was created from the earthquake that initially triggered the eruption 618 00:33:15,880 --> 00:33:18,520 Speaker 2: that had in some incredible effects as well. 619 00:33:18,960 --> 00:33:21,960 Speaker 3: Yeah, because what you've got, you know, beyond this avalanche happening, 620 00:33:22,000 --> 00:33:24,160 Speaker 3: is you've got all of a sudden, all this heat 621 00:33:24,200 --> 00:33:26,080 Speaker 3: happens in a place where there's a lot of snow, 622 00:33:26,720 --> 00:33:30,600 Speaker 3: so that snow melts, all that glacier ice melts, and 623 00:33:30,960 --> 00:33:34,440 Speaker 3: you have flooding and you have mud slides, and you 624 00:33:34,520 --> 00:33:36,520 Speaker 3: have a word that I had never even heard of before. 625 00:33:36,640 --> 00:33:40,760 Speaker 3: Ed included it in here, which was Lahar, which sounds 626 00:33:40,800 --> 00:33:43,680 Speaker 3: like just a mud slide on steroids. Yeah, like a 627 00:33:43,720 --> 00:33:48,800 Speaker 3: mudside carrying ammunition with it. And this is just raining 628 00:33:48,880 --> 00:33:52,600 Speaker 3: down everywhere and like causing a path of destruction that 629 00:33:52,600 --> 00:33:55,480 Speaker 3: hasn't been seen in like modern times in this country. 630 00:33:55,680 --> 00:33:57,960 Speaker 2: Yeah, it was like it had so much power chuck 631 00:33:58,040 --> 00:34:01,960 Speaker 2: that slide did that one part of it was carrying 632 00:34:02,040 --> 00:34:05,560 Speaker 2: chunks of rock as big as five hundred and fifty 633 00:34:05,560 --> 00:34:08,800 Speaker 2: eight feet or seven hundred and seventy meters across. Wow, 634 00:34:08,840 --> 00:34:12,200 Speaker 2: that's as big as a fifty story building. It was 635 00:34:12,280 --> 00:34:16,160 Speaker 2: moving rocks that size just fast as you can imagine, 636 00:34:16,200 --> 00:34:18,759 Speaker 2: down the mountain into the valleys. And I saw it 637 00:34:18,800 --> 00:34:21,520 Speaker 2: described as if you were watching it from a ridge, 638 00:34:21,560 --> 00:34:21,919 Speaker 2: as some. 639 00:34:21,840 --> 00:34:23,520 Speaker 1: People were, like far away. 640 00:34:24,080 --> 00:34:27,760 Speaker 2: You would see the cloud the debris starting to come 641 00:34:28,200 --> 00:34:30,719 Speaker 2: at you. It would disappear into a valley, and then 642 00:34:30,719 --> 00:34:32,160 Speaker 2: all of a sudden, it would come up over the 643 00:34:32,239 --> 00:34:36,719 Speaker 2: ridge and keep going. It was just filling valleys with 644 00:34:36,880 --> 00:34:42,200 Speaker 2: rocks and debris. It's just it's unimaginable trying to grasp 645 00:34:42,280 --> 00:34:45,799 Speaker 2: what happened. And it's even crazier that some people were 646 00:34:45,800 --> 00:34:47,720 Speaker 2: actually there watching this happen. 647 00:34:48,480 --> 00:34:49,600 Speaker 3: Crazy. 648 00:34:49,640 --> 00:34:52,560 Speaker 1: It is crazy. You want to take a break. 649 00:34:52,640 --> 00:34:54,239 Speaker 3: Yeah, we'll take a break and talk a little bit 650 00:34:54,239 --> 00:34:56,120 Speaker 3: more about the after effects right after this. 651 00:35:22,000 --> 00:35:25,000 Speaker 2: Okay, and we're back, And as Chuck promised everyone, it's. 652 00:35:25,000 --> 00:35:26,200 Speaker 1: After effect time. 653 00:35:27,120 --> 00:35:30,560 Speaker 3: Well, we talked a little bit about it. Obviously, Spirit Lake, 654 00:35:30,600 --> 00:35:32,319 Speaker 3: which we mentioned at the beginning, which was at the 655 00:35:32,320 --> 00:35:37,000 Speaker 3: base of the mountain, has a very strange effects on 656 00:35:37,120 --> 00:35:40,759 Speaker 3: bodies of water. It did two things. It made the 657 00:35:40,840 --> 00:35:44,600 Speaker 3: lake larger, but it also made it shallower, because it 658 00:35:44,680 --> 00:35:47,279 Speaker 3: just flooded all this water down there and raised it 659 00:35:47,320 --> 00:35:50,759 Speaker 3: such that the outlet was basically dammed up, and so 660 00:35:50,800 --> 00:35:52,720 Speaker 3: the lake got a whole lot bigger, but it reduced 661 00:35:52,760 --> 00:35:55,799 Speaker 3: its depth by about eighty feet. I think five years 662 00:35:55,880 --> 00:35:59,680 Speaker 3: later they built a spillway tunnel to control the depth 663 00:35:59,680 --> 00:36:04,040 Speaker 3: of the lake. Two hundred homes and cabins and about 664 00:36:04,080 --> 00:36:08,120 Speaker 3: two hundred miles of road and railways were completely obliterated. 665 00:36:08,680 --> 00:36:12,640 Speaker 2: Yeah, I also saw that lake was now two hundred 666 00:36:12,719 --> 00:36:15,839 Speaker 2: feet higher in elevation than it had been before, as 667 00:36:15,840 --> 00:36:18,800 Speaker 2: if like there was so much debris it like raised 668 00:36:18,800 --> 00:36:21,520 Speaker 2: the lake two hundred feet, even though it also made 669 00:36:21,560 --> 00:36:23,240 Speaker 2: it shallow or it's nuts. 670 00:36:22,960 --> 00:36:25,160 Speaker 3: And I think it lowered the ultimate height of Mount 671 00:36:25,200 --> 00:36:25,960 Speaker 3: Saint Helens. 672 00:36:25,760 --> 00:36:29,959 Speaker 2: Right, yeah, I can't remember. I think by like six 673 00:36:30,040 --> 00:36:33,359 Speaker 2: hundred meters or something like that. Some ridiculous amount of 674 00:36:33,400 --> 00:36:36,960 Speaker 2: height just blown off. And that was another thing too, 675 00:36:37,040 --> 00:36:39,920 Speaker 2: like the after effects of it. If you look at 676 00:36:39,920 --> 00:36:44,040 Speaker 2: Mount Saint Helens today or especially like right afterward, it 677 00:36:44,280 --> 00:36:46,919 Speaker 2: turned into like an amphitheater. Yeah, like the north side 678 00:36:47,000 --> 00:36:48,759 Speaker 2: was blown out and the other sides were kind of 679 00:36:48,800 --> 00:36:51,360 Speaker 2: curved around and what was neat is one of the 680 00:36:51,440 --> 00:36:53,799 Speaker 2: huge after effects of Mount Saint Helens. One of the 681 00:36:53,800 --> 00:36:56,239 Speaker 2: more positive ones is I saw it described as like 682 00:36:56,280 --> 00:37:01,640 Speaker 2: a crash course for volcanologists, Malls and everybody who are 683 00:37:01,680 --> 00:37:05,799 Speaker 2: now just had this amazing natural laboratory to study in, 684 00:37:06,239 --> 00:37:09,200 Speaker 2: and that the eruption, because it was the lateral blast, 685 00:37:09,600 --> 00:37:12,800 Speaker 2: opened up like basically a cross section of the mountain 686 00:37:13,120 --> 00:37:16,560 Speaker 2: that they could study. Now it's past history from the 687 00:37:16,600 --> 00:37:18,560 Speaker 2: inside out, which I thought was pretty neat. 688 00:37:18,800 --> 00:37:21,560 Speaker 3: And a young tray Anastasia said, one day I shall 689 00:37:21,600 --> 00:37:24,440 Speaker 3: play at the bates of that amphitheater. Oh did he 690 00:37:24,600 --> 00:37:26,840 Speaker 3: and bore people with noodling on. 691 00:37:26,719 --> 00:37:29,719 Speaker 1: My guitar they played there? 692 00:37:29,880 --> 00:37:31,600 Speaker 3: No, I don't think so. I don't think there's anything there. 693 00:37:31,640 --> 00:37:32,240 Speaker 3: I was just kidding. 694 00:37:32,640 --> 00:37:35,200 Speaker 2: Oh wow, that was just completely made. 695 00:37:35,320 --> 00:37:37,720 Speaker 3: I never will miss a chance to take a ticket fish. 696 00:37:38,000 --> 00:37:38,480 Speaker 1: I'm with you. 697 00:37:40,040 --> 00:37:44,760 Speaker 3: So ash is raining down and out. It literally darkened 698 00:37:44,800 --> 00:37:48,040 Speaker 3: the skies. When this ash, if you were close enough 699 00:37:48,080 --> 00:37:52,120 Speaker 3: to it, it would literally burn you alive. If you're 700 00:37:52,320 --> 00:37:54,840 Speaker 3: far away, it can just create a lot of problems, 701 00:37:54,880 --> 00:37:59,560 Speaker 3: everything from you know, just equipment not working, electrical ottages 702 00:37:59,600 --> 00:38:05,000 Speaker 3: and blacks and brown outs. Visibility is obviously terrible. As 703 00:38:05,000 --> 00:38:08,600 Speaker 3: far as crops go, certain crops were wiped out by 704 00:38:08,640 --> 00:38:12,160 Speaker 3: this ash and the toxic gases. Some of them did 705 00:38:12,200 --> 00:38:14,520 Speaker 3: a little bit better because they just got a little 706 00:38:14,520 --> 00:38:17,120 Speaker 3: bit of the ash and it ash will help promote 707 00:38:17,200 --> 00:38:20,520 Speaker 3: rainfall and hold moisture in the ground better. So apparently 708 00:38:20,520 --> 00:38:23,319 Speaker 3: wheat crops and apple crops fared pretty well. 709 00:38:24,040 --> 00:38:25,000 Speaker 1: Yeah, that was surprising. 710 00:38:25,120 --> 00:38:28,000 Speaker 2: Yeah, I also saw and there was a lot of devastation. 711 00:38:28,160 --> 00:38:31,759 Speaker 2: Any big game animal in the blast zone was I said, 712 00:38:31,840 --> 00:38:35,520 Speaker 2: big game animal, by the way, was in the blast 713 00:38:35,600 --> 00:38:40,320 Speaker 2: zone was killed without question. But they they were very surprised. 714 00:38:40,360 --> 00:38:43,880 Speaker 2: Biologists who went in to investigate shortly afterward found there 715 00:38:43,880 --> 00:38:49,279 Speaker 2: were like entire communities and ecosystems of smaller animals and plants, microbes, 716 00:38:49,360 --> 00:38:53,279 Speaker 2: fungi that had survived just fine. And we're among the 717 00:38:53,320 --> 00:38:56,040 Speaker 2: first to recolonize, and we're part of the reason why 718 00:38:57,239 --> 00:39:01,600 Speaker 2: Mount Saint Helen's ecosystem started to bound so quickly. 719 00:39:02,080 --> 00:39:05,040 Speaker 3: I mean, that's what'll happen, right if the Earth ever 720 00:39:05,160 --> 00:39:07,880 Speaker 3: just burns up into a fiery ball, that'll just become 721 00:39:07,880 --> 00:39:09,280 Speaker 3: a big mushroom field, right. 722 00:39:09,800 --> 00:39:12,879 Speaker 2: Probably, and then the animals that lived underground will come 723 00:39:12,920 --> 00:39:15,120 Speaker 2: above ground and say it's our. 724 00:39:15,000 --> 00:39:16,600 Speaker 1: Time, baby. I'll look forward to that. 725 00:39:17,000 --> 00:39:21,440 Speaker 2: For some reason, what else happened? Oh, I saw that 726 00:39:21,480 --> 00:39:25,919 Speaker 2: the ash cloud that blew finally out of the top. 727 00:39:25,960 --> 00:39:29,480 Speaker 2: We should say that the lateral blast was followed by 728 00:39:29,480 --> 00:39:33,239 Speaker 2: a plinium blast, and that shot, like you know, that 729 00:39:33,360 --> 00:39:36,120 Speaker 2: was the money volcano shot that everybody was looking for. 730 00:39:36,719 --> 00:39:40,000 Speaker 2: A plume of ash and smoke rose eighty thousand feet 731 00:39:40,080 --> 00:39:42,880 Speaker 2: into the air, and it was moving so fast that 732 00:39:42,920 --> 00:39:45,800 Speaker 2: it circled the globe in fifteen days, came back to 733 00:39:45,880 --> 00:39:48,680 Speaker 2: square one in fifteen days. And of course that was 734 00:39:48,719 --> 00:39:53,360 Speaker 2: like affecting air traffic. Do you remember that icelandic volcano 735 00:39:53,440 --> 00:39:55,479 Speaker 2: that affected air traffic in Europe for like weeks? 736 00:39:55,560 --> 00:39:58,800 Speaker 1: Yeah, weren't you stranded by that or something. No, Okay, 737 00:39:58,840 --> 00:39:59,840 Speaker 1: I don't think so. 738 00:40:00,000 --> 00:40:04,600 Speaker 2: Okay, It like they knew what to do in part 739 00:40:04,760 --> 00:40:08,399 Speaker 2: because of how Mount Saint Helen's affected air travel at 740 00:40:08,400 --> 00:40:10,839 Speaker 2: the time. They were like, this is brand new to us, 741 00:40:11,640 --> 00:40:14,600 Speaker 2: but it helped lay the ground work for understanding what 742 00:40:14,719 --> 00:40:16,400 Speaker 2: to look for, how to deal with that kind of 743 00:40:16,400 --> 00:40:17,160 Speaker 2: stuff later on. 744 00:40:17,840 --> 00:40:19,799 Speaker 3: Yeah. The the other thing I wanted to point out 745 00:40:19,800 --> 00:40:22,600 Speaker 3: too about Spirit Lake was if you look at footage 746 00:40:22,640 --> 00:40:26,000 Speaker 3: of the lake and now these kind of rivers that 747 00:40:26,080 --> 00:40:29,799 Speaker 3: were just happening, and it literally like re routed you know, 748 00:40:29,840 --> 00:40:34,040 Speaker 3: the Columbia River and the Cowlitz River in sections, but 749 00:40:34,160 --> 00:40:38,239 Speaker 3: it looks like it looks like a logging operation is happening. Yeah, 750 00:40:38,440 --> 00:40:41,000 Speaker 3: and like you could almost and may have been able. 751 00:40:41,120 --> 00:40:43,120 Speaker 3: Well obviously it's been too dangerous, but it looks like 752 00:40:43,200 --> 00:40:46,360 Speaker 3: you could have walked over these logs. They were so 753 00:40:46,719 --> 00:40:49,520 Speaker 3: like packed and these were just trees, you know, an 754 00:40:49,520 --> 00:40:50,120 Speaker 3: hour before. 755 00:40:50,719 --> 00:40:54,440 Speaker 1: Yeah, if you could do that lumberjack log rolling thing. 756 00:40:54,440 --> 00:40:57,480 Speaker 2: Yeah, you could have probably made it across the light. 757 00:40:57,560 --> 00:40:59,839 Speaker 1: We could have, but they're in that minute by minute. 758 00:41:00,080 --> 00:41:02,480 Speaker 2: But so there was a pair of like high school 759 00:41:02,480 --> 00:41:05,520 Speaker 2: sweethearts who've been camping. Yeah, and they had a harrowing 760 00:41:05,600 --> 00:41:09,640 Speaker 2: experience because they both got thrown into Spirit Lake and 761 00:41:10,360 --> 00:41:12,920 Speaker 2: the boyfriend was able to rescue the girlfriend is like 762 00:41:13,000 --> 00:41:15,080 Speaker 2: the logs were starting to close in on him. He 763 00:41:15,440 --> 00:41:17,960 Speaker 2: pulled her out from the lake and they were hanging 764 00:41:18,000 --> 00:41:20,440 Speaker 2: on to logs when they finally made it out and 765 00:41:20,480 --> 00:41:24,560 Speaker 2: were rescued. That happened like that happened to somebody. 766 00:41:24,560 --> 00:41:25,480 Speaker 3: They were in their car. 767 00:41:26,160 --> 00:41:28,440 Speaker 1: Oh, that's how they got in the lake. They were 768 00:41:28,480 --> 00:41:29,399 Speaker 1: in their car. Yeah. 769 00:41:29,440 --> 00:41:31,120 Speaker 3: They said it just picked them up and all they 770 00:41:31,160 --> 00:41:34,000 Speaker 3: were driving and then they were floating and they said 771 00:41:34,000 --> 00:41:36,200 Speaker 3: that they're you know there, she said, like my instinct 772 00:41:36,239 --> 00:41:37,680 Speaker 3: was to get out of the car, but there was 773 00:41:37,719 --> 00:41:38,880 Speaker 3: like nowhere to go. 774 00:41:39,239 --> 00:41:42,960 Speaker 2: Right yeah, because there were trees everywhere floating around beside them. 775 00:41:42,840 --> 00:41:45,239 Speaker 3: Right yeah. And this is you know, these are just 776 00:41:45,280 --> 00:41:47,719 Speaker 3: sort of That's what's so cool about the special is 777 00:41:47,760 --> 00:41:49,880 Speaker 3: it really brought in the human element of these people 778 00:41:49,920 --> 00:41:52,600 Speaker 3: that were around there, right and they you know, they 779 00:41:52,640 --> 00:41:57,239 Speaker 3: all survived because they were being interviewed. Obviously Dorothy Stoffel, 780 00:41:57,440 --> 00:42:02,279 Speaker 3: who was the geologist that was flying. I guess was 781 00:42:02,360 --> 00:42:05,719 Speaker 3: her husband Keith or was that her brother her husband Keith? 782 00:42:05,800 --> 00:42:05,880 Speaker 2: Oh? 783 00:42:05,840 --> 00:42:09,920 Speaker 3: Okay, they survived that plane flight like they got out 784 00:42:09,920 --> 00:42:13,239 Speaker 3: of there. There were stories of people that literally it 785 00:42:13,320 --> 00:42:15,759 Speaker 3: was like it from a movie, drove, you know, one 786 00:42:15,840 --> 00:42:19,239 Speaker 3: hundred and ten miles an hour, like out running this 787 00:42:19,760 --> 00:42:22,680 Speaker 3: ash debris slide coming out right. 788 00:42:23,360 --> 00:42:25,680 Speaker 2: Yeah, and some people didn't make it. So there was 789 00:42:25,760 --> 00:42:28,920 Speaker 2: one guy who was chronicled in that that was driving 790 00:42:28,960 --> 00:42:32,080 Speaker 2: as fast as he can in the blasts just caught 791 00:42:32,160 --> 00:42:35,200 Speaker 2: up with him and buried him in the in the 792 00:42:35,280 --> 00:42:40,560 Speaker 2: ash and he probably died pretty much instantly. But like again, 793 00:42:40,640 --> 00:42:43,520 Speaker 2: that happened to people. There's very famous footage of a 794 00:42:43,600 --> 00:42:49,120 Speaker 2: house just flowing down like a newly engorged mud slidey river, 795 00:42:50,120 --> 00:42:52,520 Speaker 2: moving so fast that you probably could have towed water 796 00:42:52,560 --> 00:42:55,640 Speaker 2: skiers from the house. Essentially, it was moving that fast 797 00:42:55,760 --> 00:42:58,880 Speaker 2: just down the river. So I mean again, it was 798 00:42:58,920 --> 00:43:03,400 Speaker 2: one of the most doc documented volcanic eruptions of all times. 799 00:43:03,400 --> 00:43:06,239 Speaker 2: So there's really amazing footage on there or just on 800 00:43:06,280 --> 00:43:09,160 Speaker 2: the internet, is what I mean. But that wasn't the 801 00:43:09,239 --> 00:43:13,399 Speaker 2: last time that Mount Saint Helens has erupted. I think 802 00:43:13,719 --> 00:43:17,080 Speaker 2: it erupted a few times between nineteen eighty and maybe 803 00:43:17,520 --> 00:43:21,600 Speaker 2: nineteen ninety six, I think, yeah, and then the biggest 804 00:43:21,600 --> 00:43:24,319 Speaker 2: one recently was between two thousand and four and two 805 00:43:24,360 --> 00:43:25,080 Speaker 2: thousand and eight. 806 00:43:25,719 --> 00:43:27,840 Speaker 3: Yeah, it started sort of getting a little more active 807 00:43:27,880 --> 00:43:31,360 Speaker 3: again this time though. You know, one of the things 808 00:43:31,360 --> 00:43:35,120 Speaker 3: that to the benefit of the surrounding area when a 809 00:43:35,200 --> 00:43:38,759 Speaker 3: volcano blows like that is that pressure is released and 810 00:43:38,880 --> 00:43:40,600 Speaker 3: it's going to take a long time to build back 811 00:43:40,640 --> 00:43:43,680 Speaker 3: up to that level again, kind of depending on how 812 00:43:43,719 --> 00:43:46,840 Speaker 3: it reforms on top of it. But this time, apparently 813 00:43:46,880 --> 00:43:50,480 Speaker 3: there are there are more ways for this pressure to 814 00:43:50,520 --> 00:43:53,759 Speaker 3: be released. So I think it's just sort of the 815 00:43:53,760 --> 00:43:57,200 Speaker 3: pressures being released a little more gradually since the two thousand. 816 00:43:56,840 --> 00:43:58,760 Speaker 1: And four that's my impression too. 817 00:43:59,200 --> 00:44:01,920 Speaker 3: But they do say that like, oh no, like it 818 00:44:02,000 --> 00:44:05,880 Speaker 3: will happen again, like things are there is a new 819 00:44:05,960 --> 00:44:09,600 Speaker 3: lava dome growing, and the pressure is going to build up, 820 00:44:09,640 --> 00:44:12,120 Speaker 3: and it could be in a thousand years or it 821 00:44:12,160 --> 00:44:13,280 Speaker 3: could be in ten years. 822 00:44:13,719 --> 00:44:15,239 Speaker 1: Yeah, we just don't know. 823 00:44:15,320 --> 00:44:17,759 Speaker 3: Now, but they are studying it. Like there there's a 824 00:44:17,800 --> 00:44:21,040 Speaker 3: lot of active research and study going on at Mount 825 00:44:21,040 --> 00:44:21,839 Speaker 3: Saint Helens now. 826 00:44:22,080 --> 00:44:24,080 Speaker 2: Yeah, I believe, you know, the eruption was such a 827 00:44:24,080 --> 00:44:27,560 Speaker 2: big deal that they've opened the USGS opened a research 828 00:44:27,600 --> 00:44:33,319 Speaker 2: station nearby, and also that two thousand and four activity 829 00:44:33,760 --> 00:44:35,880 Speaker 2: basically ran from two thousand and four to two thousand 830 00:44:35,880 --> 00:44:38,480 Speaker 2: and eight. Like you said, they've been studying the mountain closely. 831 00:44:38,760 --> 00:44:43,160 Speaker 2: So there's amazing time lapse footage of those four years, 832 00:44:43,760 --> 00:44:47,479 Speaker 2: and it's astounding how fast and how big Mount Saint 833 00:44:47,480 --> 00:44:51,800 Speaker 2: Helens just grows from that eruption activity called time lapse 834 00:44:51,840 --> 00:44:57,360 Speaker 2: Images of Mount Saint Helen's dome growth. It's on YouTube 835 00:44:58,440 --> 00:45:00,560 Speaker 2: and I recommend checking that as well. 836 00:45:01,200 --> 00:45:04,120 Speaker 3: Yeah, I would just be careful when you google dome growth. 837 00:45:05,960 --> 00:45:06,960 Speaker 1: Or bulge growth. 838 00:45:07,360 --> 00:45:08,759 Speaker 3: Oh boy. 839 00:45:08,960 --> 00:45:11,880 Speaker 1: So man, we are so juvenile sometimes, aren't we? 840 00:45:12,040 --> 00:45:12,360 Speaker 3: Sure? 841 00:45:12,640 --> 00:45:13,719 Speaker 1: And by we I mean me? 842 00:45:14,000 --> 00:45:14,600 Speaker 3: No, me too. 843 00:45:15,680 --> 00:45:18,680 Speaker 2: But like we said, Mount Saint Helens bounce back, Spirit 844 00:45:18,760 --> 00:45:21,160 Speaker 2: Lake open back up and the cold Water two station 845 00:45:21,360 --> 00:45:24,800 Speaker 2: has been renamed after David Johnston and there's an amazing 846 00:45:24,840 --> 00:45:27,279 Speaker 2: memorial too. I saw on some trip Advisor post that 847 00:45:27,320 --> 00:45:29,440 Speaker 2: somebody so that it was like the one of the best, 848 00:45:31,040 --> 00:45:34,600 Speaker 2: like not welcome center, but you know, information centers that 849 00:45:34,640 --> 00:45:35,719 Speaker 2: the person's ever been to. 850 00:45:35,880 --> 00:45:41,319 Speaker 1: So I would like to go there, Right, You got 851 00:45:41,320 --> 00:45:41,879 Speaker 1: anything else? 852 00:45:42,000 --> 00:45:43,680 Speaker 3: I got nothing else? All? 853 00:45:43,760 --> 00:45:44,520 Speaker 1: Right, we go. 854 00:45:44,440 --> 00:45:49,160 Speaker 2: Forth and research Mount Saint Helen's with an S. And 855 00:45:49,239 --> 00:45:52,959 Speaker 2: you can start doing that by watching Dante's Peak. Since 856 00:45:52,960 --> 00:45:55,479 Speaker 2: I said Dante's Peak, it's time for listener mail. 857 00:45:57,480 --> 00:45:59,800 Speaker 3: This is following up on an email that you particularly 858 00:46:00,280 --> 00:46:04,080 Speaker 3: from our spectacular. Okay, hey, guys, thoroughly enjoying the most 859 00:46:04,120 --> 00:46:08,279 Speaker 3: recent spectacular. The accents are comedy genius. Megal, do you 860 00:46:08,280 --> 00:46:14,319 Speaker 3: want to pop in and say Hi, Hello, perfect I'm 861 00:46:14,320 --> 00:46:15,920 Speaker 3: going to bring Migal back every now and then. By 862 00:46:15,920 --> 00:46:18,160 Speaker 3: the way, I just want to prepare you in the audience. 863 00:46:19,080 --> 00:46:21,359 Speaker 3: I wanted to address a couple of eighteen hundred's diction 864 00:46:21,520 --> 00:46:24,359 Speaker 3: issues that cause some puzzlement when you got talked about 865 00:46:24,400 --> 00:46:27,360 Speaker 3: toilet It's basically what Josh said. I've always thought of 866 00:46:27,400 --> 00:46:30,160 Speaker 3: it as a refreshing as freshening up in the bathroom, 867 00:46:30,280 --> 00:46:32,640 Speaker 3: washing her face and hands when first waking up or 868 00:46:32,640 --> 00:46:35,120 Speaker 3: going to bed. I double check with Merriam Webster, though, 869 00:46:35,160 --> 00:46:38,040 Speaker 3: and it's more generally dressing and grooming. 870 00:46:38,400 --> 00:46:39,960 Speaker 1: Okay, that makes sense. 871 00:46:40,280 --> 00:46:43,440 Speaker 3: Yeah, sure. On the other hand, the strangers in the 872 00:46:43,480 --> 00:46:46,560 Speaker 3: beverage from the toll House is a lot more puzzling. Yes, 873 00:46:46,600 --> 00:46:48,840 Speaker 3: I had no idea what it meant. And although Josh's 874 00:46:48,920 --> 00:46:51,680 Speaker 3: guess that beverage meant the pub was clever, it doesn't 875 00:46:51,680 --> 00:46:54,840 Speaker 3: really make sense, just as a reminder, the sentence is 876 00:46:54,880 --> 00:46:57,719 Speaker 3: talking about some men drinking tea in an inn and 877 00:46:57,800 --> 00:47:02,000 Speaker 3: pausing to quote discover the sex and dates of arrival 878 00:47:02,080 --> 00:47:05,160 Speaker 3: of the strangers, which floated in some numbers in the 879 00:47:05,160 --> 00:47:08,640 Speaker 3: beverage end quote. I think I found the answer, though, guys, 880 00:47:08,680 --> 00:47:12,080 Speaker 3: in a dictionary of Scottish dialect. We love this stuff. 881 00:47:12,080 --> 00:47:13,360 Speaker 1: By the way, yeah, this is amazing. 882 00:47:13,880 --> 00:47:15,880 Speaker 3: Tea leaves floating on the surface of your drink are 883 00:47:15,920 --> 00:47:18,759 Speaker 3: considered omens that you will meet someone new, So these 884 00:47:18,800 --> 00:47:21,680 Speaker 3: tea leaves are called strangers. If you pick up a 885 00:47:21,680 --> 00:47:24,799 Speaker 3: stranger and bite it, the toughness will tell you whether 886 00:47:24,880 --> 00:47:28,680 Speaker 3: the new acquaintance will be male or female. Amazing, amazing. 887 00:47:28,920 --> 00:47:30,520 Speaker 3: I'm gonna guess there's also a way to predict the 888 00:47:30,600 --> 00:47:33,040 Speaker 3: date you meet this person, although I didn't see reference 889 00:47:33,080 --> 00:47:35,399 Speaker 3: to that. So that's what the characters are doing, guys, 890 00:47:35,480 --> 00:47:38,200 Speaker 3: using tea leaves to predict the future. By the way, 891 00:47:38,280 --> 00:47:41,640 Speaker 3: other omens can also be strangers, like unburned candlewicks or 892 00:47:41,680 --> 00:47:44,160 Speaker 3: soot on grates. I've loved the show for years, look 893 00:47:44,200 --> 00:47:47,520 Speaker 3: forward to many more. That is a great email.

It was a terrible guess. 898 00:48:04,560 --> 00:48:06,600 Speaker 2: But I mean that was really hard like you. That 899 00:48:06,760 --> 00:48:10,439 Speaker 2: was obscure, you know very much.
