1 00:00:00,560 --> 00:00:03,560 Speaker 1: Hey, everyone, do you know the song Landslide sung by 2 00:00:03,560 --> 00:00:06,200 Speaker 1: Stevie Nicks. Well, this is not that. This is a 3 00:00:06,200 --> 00:00:09,080 Speaker 1: podcast about real landslides and how they work. And it's 4 00:00:09,119 --> 00:00:11,760 Speaker 1: my pick for the Saturday Select. It's a good episode 5 00:00:11,760 --> 00:00:19,880 Speaker 1: and it was from March. Check it out. Welcome to 6 00:00:19,960 --> 00:00:28,880 Speaker 1: Stuff you should know, a production of I Heart Radio. Hey, 7 00:00:28,960 --> 00:00:31,840 Speaker 1: and welcome to the podcast. I'm Josh Clark and Charles W. 8 00:00:32,159 --> 00:00:35,559 Speaker 1: Chuck Bryant is with me as always. Hello, sir, Hello, 9 00:00:35,600 --> 00:00:37,920 Speaker 1: how are you. I'm good. We've got Jerry in the house. 10 00:00:38,520 --> 00:00:41,640 Speaker 1: Oh yeah, this one, uh, you know, I probably won't 11 00:00:41,640 --> 00:00:47,000 Speaker 1: be our funniest podcast. And I have to say that 12 00:00:47,200 --> 00:00:54,000 Speaker 1: I suggested landslides without knowing about that landslide. No, I swear, no, 13 00:00:54,240 --> 00:00:56,400 Speaker 1: I promise you. I sent this to you on Monday, 14 00:00:57,000 --> 00:01:00,880 Speaker 1: and then I saw like a few hours later, wow, 15 00:01:01,160 --> 00:01:03,480 Speaker 1: and it was like, oh boy, I didn't you know. 16 00:01:03,520 --> 00:01:05,200 Speaker 1: I was. I was on vacation, so I didn't hear 17 00:01:05,240 --> 00:01:10,160 Speaker 1: about it. Um. But yeah, so it's super relevant. Well, yeah, 18 00:01:10,160 --> 00:01:14,680 Speaker 1: it is apparently unintentionally relevant like our black Boxes episode. Yeah, 19 00:01:14,760 --> 00:01:19,440 Speaker 1: it's been happening weirdly. But yeah, if you have been 20 00:01:19,840 --> 00:01:23,440 Speaker 1: uh not paying attention to the news at all lately. 21 00:01:23,600 --> 00:01:25,800 Speaker 1: Then you may not know, but there was a massive 22 00:01:26,040 --> 00:01:30,480 Speaker 1: landslide in Washington as of last count I think, um, 23 00:01:30,520 --> 00:01:33,520 Speaker 1: the death tolls at like twenty four which is an 24 00:01:33,680 --> 00:01:38,080 Speaker 1: astoundingly high number for a landslide, uh, at least in 25 00:01:38,120 --> 00:01:41,559 Speaker 1: the United States, because something like twenty five to thirty 26 00:01:41,560 --> 00:01:45,679 Speaker 1: five people die in the US a year from landslides. 27 00:01:45,760 --> 00:01:49,640 Speaker 1: This one was one single, enormous landslide. And if you 28 00:01:49,680 --> 00:01:52,960 Speaker 1: haven't seen the pictures to get an idea of just 29 00:01:53,040 --> 00:01:58,160 Speaker 1: how large it was, you should go online immediately, um 30 00:01:58,240 --> 00:02:01,400 Speaker 1: and check it out because it's it was nuts what 31 00:02:01,640 --> 00:02:04,120 Speaker 1: happened there. Yeah, it's about an hour north of Seattle, 32 00:02:04,160 --> 00:02:05,800 Speaker 1: and I know we have a lot of fans in Seattle, 33 00:02:05,840 --> 00:02:08,720 Speaker 1: so we're obviously thinking about everyone there. But um, it 34 00:02:08,880 --> 00:02:11,359 Speaker 1: is you know, there's still you know, a hundred and 35 00:02:11,400 --> 00:02:14,560 Speaker 1: seventy plus people missing, and it's it's it looks like 36 00:02:14,639 --> 00:02:18,440 Speaker 1: it will be easily the deadliest landslide in US history 37 00:02:18,480 --> 00:02:19,880 Speaker 1: by the time this is all said and done. It 38 00:02:19,919 --> 00:02:23,240 Speaker 1: seems like it. But I'm clearly hoping there's more survivors. 39 00:02:23,280 --> 00:02:26,160 Speaker 1: But it's just a scary man. Oh yeah, to think 40 00:02:26,200 --> 00:02:29,799 Speaker 1: about like being trapped like that. And possibly still alive. 41 00:02:29,840 --> 00:02:32,239 Speaker 1: It's just like the whole thing is upsetting. Yeah, because 42 00:02:32,240 --> 00:02:35,160 Speaker 1: I mean, if you were inside a structure it's now 43 00:02:35,200 --> 00:02:38,160 Speaker 1: covered with mud, you might you know, there's a chance 44 00:02:38,240 --> 00:02:41,880 Speaker 1: that you are you're not buried, the structure around you 45 00:02:41,960 --> 00:02:48,600 Speaker 1: is buried. Um. So yeah, it's uh, it's pretty awful stuff. Yeah. Um, 46 00:02:48,800 --> 00:02:51,120 Speaker 1: the to me, it's even more awful. And I read 47 00:02:51,160 --> 00:02:55,640 Speaker 1: an article where a resident, unnamed resident was saying like, yeah, 48 00:02:55,680 --> 00:02:58,600 Speaker 1: we're not mad at the authorities, but yeah, apparently they 49 00:02:58,639 --> 00:03:04,320 Speaker 1: didn't heat a lot of UM warnings. This area, the 50 00:03:04,440 --> 00:03:09,240 Speaker 1: area that was covered in the landslide was known since 51 00:03:09,320 --> 00:03:13,040 Speaker 1: the sixties. In the area is Slide Hill that the 52 00:03:13,200 --> 00:03:18,560 Speaker 1: area itself is called the Steelhead Landslide. So like imagine if, um, 53 00:03:18,680 --> 00:03:22,760 Speaker 1: the street you live on is is not an East Lake, 54 00:03:23,639 --> 00:03:27,320 Speaker 1: but in Steelhead Landslide, the landslide is in the name 55 00:03:27,400 --> 00:03:29,400 Speaker 1: of the area that you live. So it wasn't like 56 00:03:29,440 --> 00:03:33,000 Speaker 1: the biggest surprise. No, And there was a report by 57 00:03:33,040 --> 00:03:36,320 Speaker 1: the U. S. Army Corps of Engineers that predicted a 58 00:03:36,840 --> 00:03:42,000 Speaker 1: UM the potential for a large catastrophic failure right there 59 00:03:42,000 --> 00:03:45,040 Speaker 1: where it happened, And that's exactly what happened. The landslide happened. 60 00:03:45,360 --> 00:03:51,440 Speaker 1: It covered about a square mile and um is like 61 00:03:51,560 --> 00:03:54,480 Speaker 1: fifteen feet deep. Right now, Well, you can't tell people 62 00:03:54,520 --> 00:03:56,880 Speaker 1: where to live though, you know, no, you definitely can't. 63 00:03:57,080 --> 00:03:59,440 Speaker 1: I'm not saying they shouldn't have warned, but like people 64 00:03:59,480 --> 00:04:02,840 Speaker 1: still live in flood zones and people still build their 65 00:04:02,880 --> 00:04:05,480 Speaker 1: houses on the sides of a hill in Malibu, and yeah, 66 00:04:05,520 --> 00:04:07,800 Speaker 1: and I guess if you're warned and like you were 67 00:04:07,800 --> 00:04:10,360 Speaker 1: willing to take that risk and you wanted to, then yeah, 68 00:04:10,360 --> 00:04:12,360 Speaker 1: I don't want to disagree with that, but I I 69 00:04:12,400 --> 00:04:15,920 Speaker 1: don't know if um, I don't know if everybody was 70 00:04:16,200 --> 00:04:19,640 Speaker 1: as aware of the potential. But apparently there was a 71 00:04:19,760 --> 00:04:23,679 Speaker 1: landslide in the area as recently as two thousands six. Yeah, 72 00:04:23,800 --> 00:04:26,240 Speaker 1: so apparently this was the big one and it was 73 00:04:26,440 --> 00:04:28,840 Speaker 1: coming a long time and that and set off by 74 00:04:28,880 --> 00:04:31,279 Speaker 1: water in this case, right. Yeah, there was word that 75 00:04:31,400 --> 00:04:34,159 Speaker 1: possibly it was an earthquake, but they think though it was. Um, 76 00:04:34,200 --> 00:04:37,000 Speaker 1: there was a lot of rain that that came before then. 77 00:04:37,680 --> 00:04:40,240 Speaker 1: And so well, let's let's get down to explaining what 78 00:04:40,320 --> 00:04:44,920 Speaker 1: happened exactly. The landslide there is actually technically a mud slide. 79 00:04:45,640 --> 00:04:49,040 Speaker 1: UM and mud slides landslides, a bunch of other ones. 80 00:04:49,080 --> 00:04:53,160 Speaker 1: They're all they all fall under something called mass movements. Yeah, 81 00:04:53,240 --> 00:04:56,080 Speaker 1: and that is, uh, the umbrella term, and that basically 82 00:04:56,120 --> 00:05:00,279 Speaker 1: means gravity is at work moving something down a slope, 83 00:05:00,279 --> 00:05:03,160 Speaker 1: some kind of sediment. Um, it can be a landslide, 84 00:05:03,160 --> 00:05:05,440 Speaker 1: which can it is obviously devastating, or it can be 85 00:05:05,480 --> 00:05:09,520 Speaker 1: super slow over centuries. And we'll get into all that 86 00:05:09,560 --> 00:05:13,040 Speaker 1: in a minute. But um, and well we'll get into 87 00:05:13,080 --> 00:05:15,560 Speaker 1: all the triggers too. But I guess we should talk 88 00:05:15,600 --> 00:05:21,400 Speaker 1: about their categorized depending on how fast it's moving, um, 89 00:05:21,440 --> 00:05:25,960 Speaker 1: what kind of materials are being moved. Um. In every 90 00:05:25,960 --> 00:05:30,479 Speaker 1: case though, you're talking about soil moving off of bedrock, 91 00:05:30,839 --> 00:05:34,360 Speaker 1: the friction being overcome by gravity. That's exactly what a 92 00:05:34,440 --> 00:05:37,920 Speaker 1: landslide is. And it's like super fast erosion. Yeah, on 93 00:05:37,960 --> 00:05:40,960 Speaker 1: any slope you have soil over rock and it's being 94 00:05:40,960 --> 00:05:43,760 Speaker 1: held in place by friction. It's kind of scary to 95 00:05:43,760 --> 00:05:45,919 Speaker 1: think about it, really is. You know it's true, but 96 00:05:45,960 --> 00:05:48,280 Speaker 1: then when you read it, it's like wow. Yeah. I mean, 97 00:05:48,320 --> 00:05:51,320 Speaker 1: like if you've ever like dug a hole in the ground, Yeah, 98 00:05:51,640 --> 00:05:56,279 Speaker 1: it's not easy. It's not like it's not like silt 99 00:05:56,400 --> 00:05:59,320 Speaker 1: or something like that it's it's like ground, it's hard ground. 100 00:05:59,360 --> 00:06:03,240 Speaker 1: But you know that stuff is it's not fused to 101 00:06:03,480 --> 00:06:07,920 Speaker 1: the bedrock beneath it's it's there's there's a kind of um. 102 00:06:07,960 --> 00:06:10,240 Speaker 1: There's a friction that's holding it in place, and that 103 00:06:10,320 --> 00:06:13,880 Speaker 1: can that can fail. And that's that's what a landslide is. 104 00:06:14,080 --> 00:06:17,640 Speaker 1: Exactly like you said, gravity overcomes friction. Yeah, and it 105 00:06:17,680 --> 00:06:21,760 Speaker 1: can on some very large scales, it can on small scales. Um. 106 00:06:21,839 --> 00:06:25,560 Speaker 1: And then like you said, depending on the type of movement, 107 00:06:25,680 --> 00:06:29,200 Speaker 1: how it moves, what's moved. You have different categories of 108 00:06:29,240 --> 00:06:31,880 Speaker 1: mass movements. Landslides are just one of them, or a 109 00:06:31,960 --> 00:06:38,360 Speaker 1: slide is one category. There slides, creeps, slumps, and flows. Yeah, 110 00:06:38,440 --> 00:06:42,520 Speaker 1: creeps are um obviously super slow. It can be uh 111 00:06:42,680 --> 00:06:45,719 Speaker 1: months years, it can be centuries of creep. And that 112 00:06:45,880 --> 00:06:50,600 Speaker 1: is when the sediment uh when the friction is is 113 00:06:50,800 --> 00:06:53,760 Speaker 1: not working, but it's not completely destroyed, so there's still 114 00:06:53,760 --> 00:06:57,479 Speaker 1: some friction. It's just moving super slow. And that's usually 115 00:06:57,560 --> 00:07:00,560 Speaker 1: as a result of a lot of freezing and bowing 116 00:07:01,160 --> 00:07:04,240 Speaker 1: going on to change the composition of the soil. Yeah. 117 00:07:04,360 --> 00:07:09,040 Speaker 1: When the when a freeze comes through the sediment in 118 00:07:09,080 --> 00:07:13,400 Speaker 1: a soil, um is pushed upward as it freezes, and 119 00:07:13,400 --> 00:07:16,280 Speaker 1: when it thaws, it falls back downward. So what you 120 00:07:16,360 --> 00:07:19,800 Speaker 1: have if you look at it on a geological time scale, 121 00:07:20,040 --> 00:07:24,360 Speaker 1: is basically an undulation up and down of the soil 122 00:07:24,680 --> 00:07:27,840 Speaker 1: that is moving downward on a slope like millimeters at 123 00:07:27,880 --> 00:07:31,080 Speaker 1: a time. Right, and then uh, the telltale signs though 124 00:07:31,360 --> 00:07:35,280 Speaker 1: you can see that creep is happening, because telephone poles 125 00:07:35,280 --> 00:07:39,640 Speaker 1: will be kind of a skew trees or something like that. Yeah, 126 00:07:39,640 --> 00:07:42,680 Speaker 1: that means that you're standing on or looking at a 127 00:07:43,280 --> 00:07:47,080 Speaker 1: slumping slope and you won't see it happening. No, but 128 00:07:47,120 --> 00:07:49,600 Speaker 1: I can see a pretty awesome gift. I can't remember 129 00:07:49,680 --> 00:07:52,960 Speaker 1: where was it? Time lapse? Yeah, it's a time lapse gift. 130 00:07:53,600 --> 00:07:55,040 Speaker 1: And it wasn't over the course of a year. Is 131 00:07:55,080 --> 00:07:56,760 Speaker 1: over the course of I think several days in San 132 00:07:56,800 --> 00:08:00,400 Speaker 1: Bernardino or what. Everybody's just like whoa there goes. It 133 00:08:00,440 --> 00:08:04,960 Speaker 1: makes you feel unstable, Yeah, like the earth beneath your feet. Yeah, well, 134 00:08:05,000 --> 00:08:09,280 Speaker 1: I mean the the earth is a constantly evolving mass. 135 00:08:09,760 --> 00:08:12,040 Speaker 1: You know, soil is being moved from here to there, 136 00:08:12,040 --> 00:08:14,280 Speaker 1: and there's all sorts of different agents of change, but 137 00:08:14,840 --> 00:08:18,240 Speaker 1: and it moves in different ways it can creep. Yeah. Um, 138 00:08:18,280 --> 00:08:20,480 Speaker 1: I think I said a slumping slope. That's not true. 139 00:08:20,560 --> 00:08:23,800 Speaker 1: That was a creeping slope. Yes. A slump is when 140 00:08:24,240 --> 00:08:27,160 Speaker 1: you have a big chunk that breaks off as a 141 00:08:27,200 --> 00:08:31,480 Speaker 1: single whole chunk and moves. That's a slump. Yeah, And 142 00:08:31,480 --> 00:08:34,600 Speaker 1: that can be the actual thing can be called a 143 00:08:34,640 --> 00:08:37,120 Speaker 1: slump too. It can have a couple of meanings there 144 00:08:37,120 --> 00:08:39,640 Speaker 1: for that word, like the big piece can be called 145 00:08:39,679 --> 00:08:42,720 Speaker 1: a slump, or if the movement is the slump, if 146 00:08:42,720 --> 00:08:47,920 Speaker 1: they're not sliding like they used to slump uh, And 147 00:08:47,960 --> 00:08:52,040 Speaker 1: that is when um basically the base can't support this 148 00:08:52,120 --> 00:08:55,160 Speaker 1: big chunk on top of it. And again it's usually 149 00:08:55,640 --> 00:09:00,200 Speaker 1: due to uh. Moisture and water is the general cause 150 00:09:00,280 --> 00:09:03,439 Speaker 1: for slumps as well. Yeah, waters, like the primary all 151 00:09:03,520 --> 00:09:08,200 Speaker 1: time leading winning is cause of mass movements because either 152 00:09:09,120 --> 00:09:13,319 Speaker 1: like um in a slump. A good uh analogy or 153 00:09:13,360 --> 00:09:15,560 Speaker 1: a good example is if you're at the beach and 154 00:09:15,600 --> 00:09:18,640 Speaker 1: you just see like a whole um, a whole hunk 155 00:09:18,640 --> 00:09:21,360 Speaker 1: of wet sand cheer off of another hunk of wet 156 00:09:21,360 --> 00:09:25,000 Speaker 1: sand that you just witnessed the slump And actually water 157 00:09:25,240 --> 00:09:30,240 Speaker 1: can create stability for sandy, loamy or clay soil. Yeah, 158 00:09:30,280 --> 00:09:32,080 Speaker 1: like you build a sandcastle, you want the sand wet 159 00:09:32,200 --> 00:09:35,319 Speaker 1: exactly up to a point when you had too much 160 00:09:35,320 --> 00:09:37,840 Speaker 1: water becomes saturated, and then you have a slump or 161 00:09:37,840 --> 00:09:40,760 Speaker 1: you have a slider, a flow um. And then with 162 00:09:40,800 --> 00:09:44,559 Speaker 1: other types of mass movement, that water can get underneath 163 00:09:45,200 --> 00:09:49,120 Speaker 1: and interrupt the friction between the soil and the bedrock. 164 00:09:49,920 --> 00:09:52,400 Speaker 1: And that's when you have some sort of movement as well. 165 00:09:52,600 --> 00:09:55,360 Speaker 1: So that's creep and that's slump. And then finally we 166 00:09:55,400 --> 00:10:00,199 Speaker 1: have flow, which is uh just basically a soupy x 167 00:10:00,280 --> 00:10:04,679 Speaker 1: of water and rock and uh soil and other materials, 168 00:10:04,679 --> 00:10:07,559 Speaker 1: and it's just those are usually the deadliest because it 169 00:10:07,679 --> 00:10:10,719 Speaker 1: spread further. That's like a mud flower an avalanche. They 170 00:10:10,760 --> 00:10:14,600 Speaker 1: get everywhere, they'll like enter into everything. It's not just 171 00:10:14,760 --> 00:10:16,880 Speaker 1: it's just like a bunch of dirt. It's it's like 172 00:10:16,920 --> 00:10:21,600 Speaker 1: a river moving, a fast moving river of mud in debris. 173 00:10:22,000 --> 00:10:27,600 Speaker 1: And I misspoke earlier. That's um in oh So, Washington. 174 00:10:28,240 --> 00:10:31,920 Speaker 1: That's what that's what that was. That was the mud 175 00:10:31,960 --> 00:10:35,559 Speaker 1: flow that started it, that came down and covered everything 176 00:10:36,040 --> 00:10:41,360 Speaker 1: mud which actually hampered rescue UM operations because apparently it's 177 00:10:41,360 --> 00:10:44,800 Speaker 1: just like quicksand right now, suck you right in. Yeah, 178 00:10:45,120 --> 00:10:48,200 Speaker 1: so in the case of well, in the case of 179 00:10:48,240 --> 00:10:51,120 Speaker 1: anything other than a creep or slump, if you're talking 180 00:10:51,120 --> 00:10:57,640 Speaker 1: about a quick landslide, it happens just like in a snap. 181 00:10:57,760 --> 00:11:00,920 Speaker 1: It's it's going and picking up speed. But it is 182 00:11:00,960 --> 00:11:06,640 Speaker 1: the result of years and years of of like slow 183 00:11:06,720 --> 00:11:10,720 Speaker 1: steady erosion Blassically, it's not something that just happens out 184 00:11:10,800 --> 00:11:13,520 Speaker 1: or it can be triggered. We'll talk about like earthquakes 185 00:11:13,559 --> 00:11:16,920 Speaker 1: and stuff like that, but in general, it's the weathering 186 00:11:16,960 --> 00:11:20,959 Speaker 1: down of objects. And I guess the difference we should 187 00:11:21,000 --> 00:11:25,240 Speaker 1: describe between weathering and erosion is erosion is transporting the 188 00:11:25,240 --> 00:11:28,440 Speaker 1: weather material and weathering is is the actual wearing down 189 00:11:28,480 --> 00:11:31,040 Speaker 1: of that material. So they're different. Yeah. So if you 190 00:11:31,040 --> 00:11:35,080 Speaker 1: have a rock that's a nice, big solid piece, millions 191 00:11:35,120 --> 00:11:39,440 Speaker 1: of years later, it's been weathered into a bunch of soil, 192 00:11:40,160 --> 00:11:43,680 Speaker 1: and then as as as it's lost its composition, it 193 00:11:43,720 --> 00:11:46,480 Speaker 1: can move more easily, and when it moves, it's being eroded. 194 00:11:46,720 --> 00:11:51,920 Speaker 1: So erosion is the is the process of movement. The 195 00:11:51,960 --> 00:11:54,680 Speaker 1: weathering is everything that leads up to that ability for 196 00:11:54,720 --> 00:11:57,440 Speaker 1: it to be moved. Yeah, and weathering is important because 197 00:11:57,480 --> 00:12:01,360 Speaker 1: it's you're weathered landscape is going to be much more 198 00:12:01,440 --> 00:12:04,800 Speaker 1: likely the landslide. Um. That's why you'll see them in 199 00:12:05,559 --> 00:12:07,840 Speaker 1: more extreme environments where you get like tons of rain 200 00:12:08,000 --> 00:12:11,920 Speaker 1: or like a lot of snow maybe Uh, heat, cold water, 201 00:12:11,960 --> 00:12:14,760 Speaker 1: and oxygen. Those are all things that impact weathering. The 202 00:12:14,840 --> 00:12:17,720 Speaker 1: cause weathering. And there's there's two types of weathering. There's 203 00:12:17,760 --> 00:12:22,760 Speaker 1: mechanical weathering and there's chemical weathering. And mechanical weathering is basically, um, 204 00:12:22,880 --> 00:12:26,640 Speaker 1: the material is broken down, but it retains its same 205 00:12:26,720 --> 00:12:30,840 Speaker 1: chemical composition. Right it was. It's still the rock, but 206 00:12:30,880 --> 00:12:34,640 Speaker 1: it was broken down into smaller pieces of itself, um, 207 00:12:34,840 --> 00:12:38,240 Speaker 1: say by wind or something like that, or water lapping 208 00:12:38,280 --> 00:12:41,080 Speaker 1: against it. Now, if you had that pieces of those 209 00:12:41,080 --> 00:12:44,480 Speaker 1: pieces of rock that were in water that ultimately, over 210 00:12:44,559 --> 00:12:47,480 Speaker 1: the course of years dissolved it, it would be in 211 00:12:47,600 --> 00:12:51,400 Speaker 1: solution and it would no longer chemically resemble itself. That's 212 00:12:51,480 --> 00:12:57,079 Speaker 1: chemical weathering. So like if you pour acid on your hand, Uh, 213 00:12:57,120 --> 00:13:00,480 Speaker 1: it's gonna reconstitute into something else on the other and 214 00:13:00,760 --> 00:13:03,480 Speaker 1: the hole that burns through it, the stuff ends up 215 00:13:03,480 --> 00:13:05,679 Speaker 1: on the table is not really the same thing as 216 00:13:05,720 --> 00:13:09,120 Speaker 1: your hand. You just chemically weathered your hand. That's a 217 00:13:09,160 --> 00:13:13,520 Speaker 1: pretty extreme example. UM. And then you talked about the 218 00:13:13,600 --> 00:13:17,160 Speaker 1: constant state of movement on the earth that's going on 219 00:13:17,200 --> 00:13:20,080 Speaker 1: at all times. And that's basically, if you're gonna have erosion, 220 00:13:20,640 --> 00:13:23,360 Speaker 1: you're gonna have a deposit somewhere. And it's just a 221 00:13:23,360 --> 00:13:27,600 Speaker 1: constant cycle on the earth of weathering carried away by 222 00:13:27,600 --> 00:13:31,520 Speaker 1: erosion and being put somewhere else in in cases of 223 00:13:31,600 --> 00:13:36,200 Speaker 1: landslides the bottom of hills. Yeah, when we toward Guatemala, 224 00:13:36,240 --> 00:13:40,840 Speaker 1: you Jerry and I and um Or I should say me, um, 225 00:13:40,960 --> 00:13:44,720 Speaker 1: we we're at the site of a landslide that had happened. Um, 226 00:13:44,800 --> 00:13:47,320 Speaker 1: I will never forget. Yeah, And they you know, you 227 00:13:47,360 --> 00:13:51,720 Speaker 1: could still see in the sort of h jungle like forest, 228 00:13:51,880 --> 00:13:54,760 Speaker 1: the swath that had been cut through years earlier, because 229 00:13:54,800 --> 00:13:57,800 Speaker 1: all the stuff on either side was old growth and 230 00:13:57,840 --> 00:14:01,480 Speaker 1: then the stuff through the land slide slow was Yeah, 231 00:14:01,480 --> 00:14:04,480 Speaker 1: it was like it was much younger, shorter, like a 232 00:14:04,520 --> 00:14:07,240 Speaker 1: different kind of green as well. And they pointed out 233 00:14:07,240 --> 00:14:10,319 Speaker 1: that we were like twelve feet higher than uh basically 234 00:14:10,360 --> 00:14:16,320 Speaker 1: standing on uh. Yeah, the old village they were unable 235 00:14:16,360 --> 00:14:20,160 Speaker 1: to recover about two fifty people. It was really upsetting. Yeah, 236 00:14:20,240 --> 00:14:22,600 Speaker 1: and I remember their children were running around, all these 237 00:14:22,720 --> 00:14:26,080 Speaker 1: orphan children. Um, like they were just kind of they 238 00:14:26,120 --> 00:14:30,520 Speaker 1: belonged to the remaining village. Now it was really something else. 239 00:14:30,680 --> 00:14:32,280 Speaker 1: Well yeah, and just when they said, like you're like 240 00:14:32,280 --> 00:14:35,800 Speaker 1: twelve feet higher than just the whole land raised up 241 00:14:36,280 --> 00:14:38,160 Speaker 1: because of this month's line. It was one of those 242 00:14:38,160 --> 00:14:39,600 Speaker 1: ones that like you just kind of chewed on for 243 00:14:39,640 --> 00:14:41,880 Speaker 1: a little while before you finally understood like the full 244 00:14:41,920 --> 00:14:44,200 Speaker 1: gravity of it. Even though like while while I was 245 00:14:44,240 --> 00:14:46,400 Speaker 1: standing there, I was like, oh, this is nuts. And 246 00:14:46,520 --> 00:14:48,840 Speaker 1: the more I thought about it, think the nut of 247 00:14:48,840 --> 00:14:53,520 Speaker 1: your got uh So the sediment um, we we talked 248 00:14:53,560 --> 00:14:55,920 Speaker 1: about the deposition at the bottom of the hill. The 249 00:14:55,960 --> 00:14:59,080 Speaker 1: sediment is known as talus, right, let's the official word 250 00:14:59,080 --> 00:15:01,880 Speaker 1: for it when when it's from a landslide. Yeah, yeah, 251 00:15:02,160 --> 00:15:05,160 Speaker 1: that's what's being carried down. And um, with erosion, there 252 00:15:05,160 --> 00:15:07,480 Speaker 1: are five different things that can act on it, which 253 00:15:07,520 --> 00:15:11,320 Speaker 1: are water, which we've covered in wind and then gravity 254 00:15:11,360 --> 00:15:13,680 Speaker 1: of course which we mentioned, and then waves and glaciers too. 255 00:15:13,960 --> 00:15:17,360 Speaker 1: And technically gravity is a part of all of them, right, Yeah, 256 00:15:17,360 --> 00:15:21,320 Speaker 1: that's true, a part of all mass movement. But um, 257 00:15:21,360 --> 00:15:24,800 Speaker 1: those five agents of erosion, there are different things that 258 00:15:24,880 --> 00:15:30,280 Speaker 1: can trigger a landslide or a mass movement. Um and 259 00:15:30,280 --> 00:15:32,000 Speaker 1: and really if you think about it all, a mass 260 00:15:32,040 --> 00:15:36,280 Speaker 1: movement is like a landslide. It's just erosion in at 261 00:15:36,360 --> 00:15:39,920 Speaker 1: high speed. Sudden and high speed erosion is is basically 262 00:15:39,920 --> 00:15:43,240 Speaker 1: what that is. Rather than taking millions of years to 263 00:15:43,320 --> 00:15:45,840 Speaker 1: move from here to there through wind or waves or whatever, 264 00:15:46,320 --> 00:15:49,600 Speaker 1: it's just happens in a moment, and it happens on mass. 265 00:16:03,040 --> 00:16:16,240 Speaker 1: That's sky should all right. So we mentioned triggers, Uh, 266 00:16:16,880 --> 00:16:18,960 Speaker 1: the landside always has to have a trigger, that has 267 00:16:18,960 --> 00:16:21,840 Speaker 1: to be something to actually set it off, even though 268 00:16:22,080 --> 00:16:24,840 Speaker 1: it maybe years and years in the making. Something finally 269 00:16:25,000 --> 00:16:29,720 Speaker 1: pushes that button to make it happen. Um. It forces 270 00:16:29,800 --> 00:16:34,160 Speaker 1: gravity to overcome friction, that's right. One of the things 271 00:16:34,360 --> 00:16:38,240 Speaker 1: that we mentioned already in the case of Washington was water, 272 00:16:38,480 --> 00:16:42,600 Speaker 1: and that is probably the most common heavy rainfall I 273 00:16:42,680 --> 00:16:45,240 Speaker 1: know in California and Los Angeles. When you see houses 274 00:16:45,280 --> 00:16:48,040 Speaker 1: slipping off the hill in Malibu because they don't get 275 00:16:48,040 --> 00:16:49,400 Speaker 1: a lot of rain and when they do, things like 276 00:16:49,480 --> 00:16:53,000 Speaker 1: that happen. Yeah, And it's either water saturating the ground 277 00:16:53,040 --> 00:16:55,560 Speaker 1: and just making it so heavy that it flows downward, 278 00:16:56,160 --> 00:16:59,760 Speaker 1: or it gets down in between the soil and the 279 00:17:00,200 --> 00:17:03,600 Speaker 1: rock and just causes the whole thing to undermines everything 280 00:17:04,000 --> 00:17:08,480 Speaker 1: either way. Water equals a lot of movement. Earthquakes that 281 00:17:08,560 --> 00:17:12,800 Speaker 1: can definitely trigger a landslide. Um. We've covered earthquakes. You 282 00:17:12,840 --> 00:17:13,960 Speaker 1: should go listen to that show if you have, and 283 00:17:14,040 --> 00:17:16,359 Speaker 1: it's a good one. But you've got the vibrating of 284 00:17:16,400 --> 00:17:19,320 Speaker 1: the Earth's crust and that UM is going to disrupt 285 00:17:19,359 --> 00:17:23,600 Speaker 1: that friction pretty easily. Another big one is wildfires, which 286 00:17:23,640 --> 00:17:25,680 Speaker 1: you would think, well, how would a wildfire trigger that. 287 00:17:25,800 --> 00:17:29,920 Speaker 1: I'll tell you how UM. Vegetation, the roots of vegetation 288 00:17:30,320 --> 00:17:35,480 Speaker 1: can lock soil into basically a totally solid, cemented state, 289 00:17:36,240 --> 00:17:38,919 Speaker 1: and as long as you have thick vegetation on a slope, 290 00:17:39,480 --> 00:17:42,200 Speaker 1: it's gonna be fairly stable. When a fire comes through 291 00:17:42,280 --> 00:17:44,800 Speaker 1: burns out all the vegetation, it often burns the roots 292 00:17:44,840 --> 00:17:49,280 Speaker 1: as well, leaving not only less stable soil, but actual 293 00:17:49,440 --> 00:17:52,600 Speaker 1: pockets in that soil too, So now it's kind of pebbled, 294 00:17:52,920 --> 00:17:55,480 Speaker 1: which makes it a lot more vulnerable the landslides after 295 00:17:55,600 --> 00:17:58,520 Speaker 1: a wildfire. Yeah, I would I'm just guessing here, but 296 00:17:58,520 --> 00:18:01,960 Speaker 1: I would guess a landslide could happen like even long 297 00:18:02,000 --> 00:18:05,120 Speaker 1: after wildfire, Like if those roots die away, it would 298 00:18:05,119 --> 00:18:09,479 Speaker 1: just become even less stable. Uh, and then volcanoes. Uh, 299 00:18:09,920 --> 00:18:12,480 Speaker 1: volcanic action is a big cause. And there are a 300 00:18:12,560 --> 00:18:17,600 Speaker 1: couple of um different kinds of flows that can contribute 301 00:18:17,600 --> 00:18:20,040 Speaker 1: to a landslide from a volcano. When it's called a 302 00:18:20,119 --> 00:18:25,560 Speaker 1: pyroclastic flow, and that is after your dome has collapsed 303 00:18:25,680 --> 00:18:29,720 Speaker 1: or during interruption. And these are super high speed. They've 304 00:18:29,720 --> 00:18:34,440 Speaker 1: clocked him at four hundred and fifty miles ad degrees fahrenheit. Yeah, 305 00:18:34,520 --> 00:18:38,119 Speaker 1: lava flowing at you at four I can't even imagine that, 306 00:18:38,440 --> 00:18:42,400 Speaker 1: like cage, like seven hundred and twenty four kilometers per hour, 307 00:18:44,040 --> 00:18:48,520 Speaker 1: that's easier. Well, there you go. Then you just imagine four. Yeah, 308 00:18:48,560 --> 00:18:50,119 Speaker 1: but I mean I don't even know what that looks like, 309 00:18:50,920 --> 00:18:55,520 Speaker 1: you know, or death, yeah, exactly. Uh. And then they 310 00:18:55,520 --> 00:18:58,359 Speaker 1: are something called a lahar, which is an Indonesian word. 311 00:18:59,119 --> 00:19:02,440 Speaker 1: And this isn't uh it doesn't have to be during interruption, 312 00:19:02,720 --> 00:19:05,520 Speaker 1: but it can be. And it is set off by 313 00:19:05,600 --> 00:19:09,000 Speaker 1: water as well. Um, it's almost always near something called 314 00:19:09,040 --> 00:19:13,119 Speaker 1: a stratovolcano, which are like super steep cones, and a 315 00:19:13,200 --> 00:19:15,280 Speaker 1: lot of times there's either a crater lake or it's 316 00:19:15,320 --> 00:19:19,240 Speaker 1: snow capped up top, and so that's the water agent. 317 00:19:19,920 --> 00:19:21,440 Speaker 1: A lot of times. It's the snow and it it 318 00:19:21,600 --> 00:19:24,720 Speaker 1: sort of looks like wet concrete flowing downhill. Yeah, and 319 00:19:24,800 --> 00:19:27,199 Speaker 1: it may or may not be set off during an 320 00:19:27,240 --> 00:19:30,720 Speaker 1: actual volcanic eruption. It can happen anytime. Yeah, and it's 321 00:19:30,880 --> 00:19:34,399 Speaker 1: it's much slower, you know, an hour, but still if 322 00:19:34,440 --> 00:19:37,359 Speaker 1: you're in a golf cart, you're dead. Yeah, that's a 323 00:19:37,400 --> 00:19:40,520 Speaker 1: good point. Uh And while it's not fast, it has 324 00:19:40,760 --> 00:19:44,040 Speaker 1: um a lot more rock. So it is one of 325 00:19:44,119 --> 00:19:47,480 Speaker 1: the deadliest a lahar is I think because of just 326 00:19:47,640 --> 00:19:50,600 Speaker 1: the shoot, like you can carry like a big boulder, Yes, 327 00:19:50,960 --> 00:19:54,479 Speaker 1: in the middle of that wet concrete, plus of volcano also. Um, 328 00:19:55,119 --> 00:19:59,040 Speaker 1: it's just it's not very stable because the composition of 329 00:19:59,080 --> 00:20:02,360 Speaker 1: it is usually pretty loose rocky soil. Uh So Yeah, 330 00:20:02,359 --> 00:20:05,120 Speaker 1: if you had water, it immediately turns the slurry um 331 00:20:05,600 --> 00:20:08,920 Speaker 1: and when they erupt, they tend to shake the ground 332 00:20:08,960 --> 00:20:12,520 Speaker 1: a little bit, which is what happened in the largest 333 00:20:12,640 --> 00:20:18,240 Speaker 1: recorded landslide in Mount St. Helen's. Everybody knows the eruption, 334 00:20:19,480 --> 00:20:23,000 Speaker 1: but there was actually an attendant landslide that's on YouTube 335 00:20:23,200 --> 00:20:24,719 Speaker 1: you can check out. As a matter of fact, Um, 336 00:20:25,040 --> 00:20:29,440 Speaker 1: we're putting a post up of just amazing landslide footage 337 00:20:29,960 --> 00:20:32,480 Speaker 1: that you can check out on our website. UM, just 338 00:20:32,600 --> 00:20:34,160 Speaker 1: go to stuff you Should Know dot com and check 339 00:20:34,200 --> 00:20:37,840 Speaker 1: out that post. There's just a just some crazy stuff 340 00:20:37,840 --> 00:20:40,399 Speaker 1: that people just happened to be filming and all of 341 00:20:40,480 --> 00:20:44,879 Speaker 1: a sudden, the earth changes right before your eyes. And 342 00:20:45,000 --> 00:20:47,600 Speaker 1: one of them is this Mount St. Helen's eruption, where 343 00:20:47,800 --> 00:20:50,920 Speaker 1: just the whole mountain is basically just melting in front 344 00:20:51,000 --> 00:20:53,840 Speaker 1: of you. I remember that one, do you know? Yeah, 345 00:20:54,040 --> 00:20:57,200 Speaker 1: that was only four I was nine, so it was 346 00:20:57,240 --> 00:21:00,840 Speaker 1: on my radio. Yeah. Uh, that one traveled at speeds 347 00:21:00,880 --> 00:21:04,200 Speaker 1: of a hundred and fifty miles and again Washington State, 348 00:21:05,160 --> 00:21:08,679 Speaker 1: not getting a break, destroyed twenty seven bridges, about two 349 00:21:08,760 --> 00:21:13,280 Speaker 1: hundred homes, miles and miles of road, and covered three 350 00:21:13,320 --> 00:21:18,880 Speaker 1: square miles with debris. Yeah, that was a Mount St. Helens. Well, 351 00:21:18,920 --> 00:21:21,600 Speaker 1: you know, it's just the landslide. Another another frequent hazard 352 00:21:21,800 --> 00:21:25,320 Speaker 1: associated with landslides is you think about it, um, when 353 00:21:25,400 --> 00:21:27,680 Speaker 1: all of this earth is coming down, it's coming downward 354 00:21:28,680 --> 00:21:31,520 Speaker 1: into a lower space, which is very frequently a valley, 355 00:21:31,880 --> 00:21:35,000 Speaker 1: which is very frequently a river valley, which means that 356 00:21:35,080 --> 00:21:37,840 Speaker 1: the river is dam now, so it's flooding behind it, 357 00:21:38,720 --> 00:21:41,440 Speaker 1: right so you have a flood a flood hazard immediately, 358 00:21:42,080 --> 00:21:45,520 Speaker 1: and then if that river or if that damn breaks, 359 00:21:46,240 --> 00:21:48,800 Speaker 1: then you have another flood hazard down river all of 360 00:21:48,840 --> 00:21:51,760 Speaker 1: a sudden too, which is something that's going on in 361 00:21:51,920 --> 00:21:54,880 Speaker 1: Washington right now. Yeah, the same thing happened in Um. 362 00:21:55,200 --> 00:21:58,359 Speaker 1: I think it's the most expensive landslide in US history. 363 00:21:58,400 --> 00:22:03,600 Speaker 1: In thistle Utah uh in N, the same thing happened there. 364 00:22:03,720 --> 00:22:07,720 Speaker 1: It damned up the Spanish Fork River and caused like 365 00:22:07,880 --> 00:22:10,800 Speaker 1: much more problems just because of the flooding. And that 366 00:22:11,040 --> 00:22:15,639 Speaker 1: was two hundred million dollar fix in four dollars, and 367 00:22:16,080 --> 00:22:18,200 Speaker 1: that was even when Reagan was in office. So it's 368 00:22:18,240 --> 00:22:22,639 Speaker 1: not too much different from the two thousand uh. The 369 00:22:22,920 --> 00:22:25,800 Speaker 1: submarine landslide we should probably talk about that is in 370 00:22:25,880 --> 00:22:30,240 Speaker 1: the ocean, and that is you can you can have 371 00:22:30,760 --> 00:22:35,880 Speaker 1: an earthquake under the ocean triggering a landslide underwater, which 372 00:22:35,920 --> 00:22:39,280 Speaker 1: will trigger a tsunami. Yeah, I can a one to 373 00:22:39,480 --> 00:22:43,680 Speaker 1: three punch basically of natural disasters happening all in concert. 374 00:22:44,520 --> 00:22:46,560 Speaker 1: Um that and then actually I don't know if this 375 00:22:46,720 --> 00:22:51,439 Speaker 1: really technically counts, but it's seeing that um little bit 376 00:22:51,880 --> 00:22:57,280 Speaker 1: triggered a memory of the Lake Penur disaster in Louisiana 377 00:22:57,440 --> 00:23:02,040 Speaker 1: in night, Texico is drilling in Lake Penyr and apparently 378 00:23:02,119 --> 00:23:04,600 Speaker 1: they didn't consult the map closely enough, and they were 379 00:23:04,640 --> 00:23:09,479 Speaker 1: using a fourteen inch diameter drill and they drilled into 380 00:23:09,560 --> 00:23:12,800 Speaker 1: the lake bottom which was on top of a salt mine, 381 00:23:13,320 --> 00:23:17,680 Speaker 1: and they drilled into an operational salt mine, and the 382 00:23:17,880 --> 00:23:21,800 Speaker 1: lake got sucked into the hole in the giant whirlpool. 383 00:23:22,640 --> 00:23:25,800 Speaker 1: UM that took about like thirty to fifty of the 384 00:23:25,920 --> 00:23:29,159 Speaker 1: surrounding acreage around the lake in into the lake with it. 385 00:23:29,920 --> 00:23:33,880 Speaker 1: Eleven barges were sucked in the um flow of water 386 00:23:34,000 --> 00:23:36,639 Speaker 1: reverse so it went from freshwater to salt water. It 387 00:23:36,840 --> 00:23:39,800 Speaker 1: sucked the gulf into it for a second, and then 388 00:23:40,080 --> 00:23:42,199 Speaker 1: a couple of days later after they were like four 389 00:23:42,320 --> 00:23:44,879 Speaker 1: hundred foot geysers as like these shafts were filling with 390 00:23:45,000 --> 00:23:49,080 Speaker 1: water and the air was being displaced and um, a 391 00:23:49,160 --> 00:23:52,000 Speaker 1: couple of days later, after the water pressure stabilized, like 392 00:23:52,240 --> 00:23:54,679 Speaker 1: nine of the barges popped back up and like went 393 00:23:54,760 --> 00:23:57,880 Speaker 1: back to floating after being sucked down into this diamond mine. 394 00:23:57,920 --> 00:24:00,520 Speaker 1: It's crazy and then nuts and apparently they're a aotage 395 00:24:00,560 --> 00:24:04,080 Speaker 1: of it. It's it's awesome. It's like just The most 396 00:24:04,080 --> 00:24:06,760 Speaker 1: amazing thing, I guess more amazing than that is no 397 00:24:06,880 --> 00:24:09,280 Speaker 1: one died. Wow. Yeah, there was one guy on the 398 00:24:09,400 --> 00:24:13,119 Speaker 1: lake who was operating the drill. He got all and 399 00:24:13,200 --> 00:24:14,800 Speaker 1: then there was a guy fishing on the lake and 400 00:24:14,920 --> 00:24:17,680 Speaker 1: he zoomed his boat to shore and made it like 401 00:24:17,880 --> 00:24:19,800 Speaker 1: wild when far enough that he made it. But I 402 00:24:19,880 --> 00:24:23,920 Speaker 1: think three dogs died a lake pen your p E 403 00:24:24,200 --> 00:24:26,960 Speaker 1: I G N E U R disaster check it out. 404 00:24:27,040 --> 00:24:32,520 Speaker 1: I was all excited and then the um man, that's crazy. 405 00:24:33,520 --> 00:24:35,760 Speaker 1: There had to be some sort of erosion going on there, 406 00:24:35,800 --> 00:24:40,080 Speaker 1: and technically it was submarine erosion. Um. The most deadly 407 00:24:40,960 --> 00:24:44,240 Speaker 1: landslide in the history of the world is was a 408 00:24:44,440 --> 00:24:48,720 Speaker 1: nineteen twenty in China, December of nineteen twenty. It was 409 00:24:48,760 --> 00:24:53,040 Speaker 1: triggered by an earthquake and as many as two hundred 410 00:24:53,080 --> 00:24:55,520 Speaker 1: thousand people died in that one, and some of that 411 00:24:55,640 --> 00:24:57,520 Speaker 1: was from the earthquake, but they said the landslide was 412 00:24:57,560 --> 00:25:00,440 Speaker 1: responsible for most of the deaths. Yeah. Like I said, 413 00:25:00,560 --> 00:25:02,960 Speaker 1: in the US, it's like twenty to thirty five deaths 414 00:25:03,000 --> 00:25:06,480 Speaker 1: a year. Worldwide, it's more like four thousand, and then 415 00:25:06,800 --> 00:25:10,680 Speaker 1: on on years where there's terrible earthquakes, it will go 416 00:25:10,840 --> 00:25:13,800 Speaker 1: up into the tens of thousands. Um. And then there 417 00:25:13,880 --> 00:25:15,920 Speaker 1: was there was a MUDs like for there was a 418 00:25:15,960 --> 00:25:20,560 Speaker 1: mud slide in in Vargus, state of Venezuela that killed 419 00:25:20,600 --> 00:25:23,000 Speaker 1: like thirty thousand people. It just covered a bunch of 420 00:25:23,080 --> 00:25:25,520 Speaker 1: towns like all at once. It was a mud slide 421 00:25:25,640 --> 00:25:28,880 Speaker 1: or mud flow. I guess. Well. One thing I thought 422 00:25:29,000 --> 00:25:31,400 Speaker 1: was interesting was that UM and I think Jennifer points 423 00:25:31,440 --> 00:25:33,879 Speaker 1: us out early in the article that while in the 424 00:25:34,080 --> 00:25:36,840 Speaker 1: States we don't see a lot of UH deaths from 425 00:25:36,920 --> 00:25:41,720 Speaker 1: landslides each year, they're the most expensive natural disaster over 426 00:25:42,520 --> 00:25:47,359 Speaker 1: I think tornadoes, earthquakes combined in this country. And if 427 00:25:47,440 --> 00:25:51,360 Speaker 1: you will consult your homeowners insurance, you will almost definitely 428 00:25:51,440 --> 00:26:09,360 Speaker 1: find that the landslides are not covered. Yeah. Noope, that's 429 00:26:11,520 --> 00:26:21,520 Speaker 1: sky should know. Well, I guess we should get to 430 00:26:21,600 --> 00:26:24,080 Speaker 1: that point then that or is it us? Is it 431 00:26:24,480 --> 00:26:30,480 Speaker 1: humans that are causing these things? Yes? Always, not always. No. 432 00:26:30,760 --> 00:26:32,879 Speaker 1: Animals can cause it, like a goat can cause a 433 00:26:33,200 --> 00:26:37,920 Speaker 1: landslide if it really is unsure footed. But goats don't 434 00:26:38,000 --> 00:26:44,080 Speaker 1: blast mountain tops with dynamite that's wine. Yeah, they don't DeForest. Yeah, 435 00:26:44,200 --> 00:26:47,720 Speaker 1: Defourestation is a big problem road building and through the mountains. Yeah, 436 00:26:47,720 --> 00:26:50,000 Speaker 1: because think about it, when you have a mountain and 437 00:26:50,240 --> 00:26:52,399 Speaker 1: you cut a road through it, all of a sudden, 438 00:26:52,440 --> 00:26:55,640 Speaker 1: what was once a relatively gentle slope are now too 439 00:26:55,720 --> 00:26:59,360 Speaker 1: steep slopes on either side just aiming right at the road. Well, yeah, 440 00:26:59,359 --> 00:27:01,320 Speaker 1: and I think everyone it's probably driven on mountain roads 441 00:27:01,359 --> 00:27:05,080 Speaker 1: where they either have uh, chain link fencing on the 442 00:27:05,119 --> 00:27:08,640 Speaker 1: side of it, which is scary enough, or I guess 443 00:27:08,720 --> 00:27:10,800 Speaker 1: it's even scarier when they don't have fencing, but they 444 00:27:10,880 --> 00:27:13,639 Speaker 1: have signs that say, you know, watch out for falling 445 00:27:13,760 --> 00:27:18,360 Speaker 1: rocks or good luck pal. Yeah. Um. There are things 446 00:27:18,440 --> 00:27:21,760 Speaker 1: that people are doing though. When they do build roads, 447 00:27:21,840 --> 00:27:25,520 Speaker 1: they sometimes we'll put in drainage pipes to carry away water, 448 00:27:25,920 --> 00:27:30,960 Speaker 1: which helps h in permeable membranes like plastic sheeting. Yeah, 449 00:27:31,200 --> 00:27:36,280 Speaker 1: so it can't trickle down. Yeah, retaining walls and reforestation. 450 00:27:37,119 --> 00:27:39,760 Speaker 1: So if you're gonna clear cut an area, if you're 451 00:27:39,760 --> 00:27:42,840 Speaker 1: gonna harvest timber, maybe go back in there and try 452 00:27:42,920 --> 00:27:49,440 Speaker 1: and reforest plant something. Yeah, you know, numbersture. I can't 453 00:27:49,440 --> 00:27:52,800 Speaker 1: believe that that's not a law that if you take 454 00:27:53,240 --> 00:27:55,520 Speaker 1: X number of trees down, you have to plant x 455 00:27:55,640 --> 00:27:57,560 Speaker 1: number of trees and the number you plant should be 456 00:27:57,640 --> 00:27:59,880 Speaker 1: more than the number you took. Is that not a law? 457 00:28:00,160 --> 00:28:03,320 Speaker 1: I'm I'm quite sure it's not. We can't even get 458 00:28:03,400 --> 00:28:07,320 Speaker 1: black box recorders ejected for an extra like fifty bucks 459 00:28:07,359 --> 00:28:11,280 Speaker 1: a plane. Remember, I remember, there's no law for that. Hey. 460 00:28:11,359 --> 00:28:13,200 Speaker 1: But here in Georgia, we just passed the law where 461 00:28:13,920 --> 00:28:17,840 Speaker 1: you can bring guns into churches and uh bars, oh, 462 00:28:17,920 --> 00:28:20,440 Speaker 1: I thought you were gonna say that. I'm actually rejoicing 463 00:28:20,480 --> 00:28:23,440 Speaker 1: for another law. I don't know if it was signed 464 00:28:23,480 --> 00:28:24,840 Speaker 1: in the law or if the House passed it and 465 00:28:24,880 --> 00:28:27,920 Speaker 1: it's on its way. It is now a crime to 466 00:28:28,200 --> 00:28:33,040 Speaker 1: drive slow in the fast lane, or it will soon 467 00:28:33,080 --> 00:28:35,600 Speaker 1: be when they passed this law. Give me some parameters, 468 00:28:35,680 --> 00:28:38,120 Speaker 1: do you know? Called the slow poke bill? Okay, And 469 00:28:38,480 --> 00:28:41,000 Speaker 1: if you are impeding the flow of traffic, not even 470 00:28:41,400 --> 00:28:44,760 Speaker 1: if you're going under fifty five or under forty five. 471 00:28:45,360 --> 00:28:48,680 Speaker 1: They're so aware that Georgia drives fast that they say, 472 00:28:48,800 --> 00:28:51,320 Speaker 1: if you're impeding the flow of traffic, even if other 473 00:28:51,400 --> 00:28:53,800 Speaker 1: people are breaking the law and you're going the speed limit, 474 00:28:54,400 --> 00:28:56,560 Speaker 1: you are breaking the law by being a slow poke 475 00:28:56,600 --> 00:28:58,880 Speaker 1: in the fast lane, which is the most glorious law 476 00:28:59,040 --> 00:29:02,760 Speaker 1: any any city or state has ever come up with. Well, 477 00:29:03,400 --> 00:29:06,760 Speaker 1: if he states right, if you go to Europe, the 478 00:29:06,880 --> 00:29:08,920 Speaker 1: left lane is just for passing, Like, you shouldn't even 479 00:29:08,960 --> 00:29:11,320 Speaker 1: be traveling in the left lane. Right, it's supposed to 480 00:29:11,400 --> 00:29:14,320 Speaker 1: be you go around someone and then you stay out 481 00:29:14,360 --> 00:29:17,000 Speaker 1: of it. It's supposed to be that way here too. Boy, 482 00:29:17,080 --> 00:29:19,880 Speaker 1: it ain't. No. But if you've got the chops, you 483 00:29:19,960 --> 00:29:21,719 Speaker 1: can travel in the fast lane, as long as you're 484 00:29:21,760 --> 00:29:24,280 Speaker 1: not holding people up, the ones that are really like 485 00:29:24,720 --> 00:29:26,520 Speaker 1: you need to go to jail, or ones that are 486 00:29:26,640 --> 00:29:30,160 Speaker 1: just knowingly or like, I'm driving the speed limit so right, 487 00:29:30,280 --> 00:29:33,040 Speaker 1: you don't own the road. It's like, well, there's ten 488 00:29:33,120 --> 00:29:36,120 Speaker 1: people behind you that you're holding up, So you're the 489 00:29:36,160 --> 00:29:38,320 Speaker 1: one who goes to jail. Now in Georgia, that's gonna 490 00:29:38,320 --> 00:29:42,959 Speaker 1: be tough to enforce. It's totally subjective to I mean, 491 00:29:43,040 --> 00:29:45,840 Speaker 1: it's like a cop can.

Hey, guys, I 505 00:30:28,680 --> 00:30:30,800 Speaker 1: want to send out a note from the Great North. 506 00:30:31,200 --> 00:30:33,040 Speaker 1: I've been listening since my buddy Adam played me the 507 00:30:33,120 --> 00:30:36,200 Speaker 1: Lego podcast a few years ago, and since then I've 508 00:30:36,200 --> 00:30:39,120 Speaker 1: been a fairly regular listener, but never more so than 509 00:30:39,200 --> 00:30:41,600 Speaker 1: over the past few months because last spring I moved 510 00:30:41,600 --> 00:30:45,400 Speaker 1: from Minneapolis to Juneau, Alaska for job gardening at a 511 00:30:45,480 --> 00:30:48,840 Speaker 1: public uh arboretum. It sounds like a lovely job. By 512 00:30:48,880 --> 00:30:51,360 Speaker 1: the way, well, I live in a little shack in 513 00:30:51,400 --> 00:30:53,880 Speaker 1: the woods near my work, about twenty five miles out 514 00:30:53,920 --> 00:30:56,400 Speaker 1: of town, about a half a mile from my nearest neighbor, 515 00:30:56,800 --> 00:31:00,800 Speaker 1: almost free of rent. Close proximity to work, and uniqueness 516 00:31:00,840 --> 00:31:02,920 Speaker 1: of the situation is what drew me to it. I 517 00:31:03,000 --> 00:31:06,320 Speaker 1: have no internet, I have no cell phone service, so um. 518 00:31:06,760 --> 00:31:08,480 Speaker 1: Every time I head into town, I stopped by the 519 00:31:08,560 --> 00:31:12,360 Speaker 1: library or a coffee shop and download more of your podcasts. Uh, 520 00:31:12,560 --> 00:31:14,719 Speaker 1: new stuff and oldies, but goodies that are still new 521 00:31:14,760 --> 00:31:17,480 Speaker 1: to me. I have gotten into the habit of listening 522 00:31:17,520 --> 00:31:20,480 Speaker 1: to you guys most evenings while making or eating dinner. 523 00:31:20,840 --> 00:31:22,920 Speaker 1: I know some people in our town, but in the 524 00:31:23,000 --> 00:31:25,640 Speaker 1: interest of using less gasoline and sparing my more or 525 00:31:25,720 --> 00:31:28,720 Speaker 1: less meager bank account, I spend the majority of my 526 00:31:28,920 --> 00:31:33,320 Speaker 1: nights out here alone. Whenever I do go into town, UM, 527 00:31:33,560 --> 00:31:34,960 Speaker 1: or one of my friends makes their way out here, 528 00:31:35,000 --> 00:31:37,040 Speaker 1: I tell them about whatever I've learned from you guys. 529 00:31:37,800 --> 00:31:40,320 Speaker 1: Listening to you banter and learning a lot of interesting 530 00:31:40,360 --> 00:31:42,480 Speaker 1: new things has definitely helped me keep my firm grip 531 00:31:42,560 --> 00:31:46,800 Speaker 1: on my sanity. Uh. Winter is basically wrapping up here. 532 00:31:46,960 --> 00:31:49,880 Speaker 1: It was long and harsh. We had ninety six inches 533 00:31:49,920 --> 00:31:57,040 Speaker 1: of snow in December alone. Well, I'm really looking forward 534 00:31:57,080 --> 00:31:59,920 Speaker 1: to springing summer when Alaska comes to life with tour 535 00:32:00,320 --> 00:32:03,400 Speaker 1: seasonal workers in long, sunny days.

It's a beautiful spot and a good adventure, 539 00:32:10,880 --> 00:32:13,520 Speaker 1: but would have been a lot more difficult without the 540 00:32:13,640 --> 00:32:17,600 Speaker 1: company of you guys. You rule. And that is from 541 00:32:17,640 --> 00:32:20,080 Speaker 1: Will and Will. That sounds like my kind of life, Buddy, 542 00:32:20,080 --> 00:32:22,520 Speaker 1: I'd love to do that. That is your Union bomb risk. 543 00:32:23,280 --> 00:32:27,479 Speaker 1: I could sands the bombing. I could be the UNI bomber.
