(author note:) Since we are covering numerous controversial topics in this video, I wanted to be sure and include lots of links for you to do your own research on. One of the most important points to keep in mind though, is that water and erosion are scale-invariant. In other words we can see the same shapes and patterns, but on radically different scales. The small current ripples that you see along the creek can be found at West Bar Ripples in Washington, but these are orders-of-magnitude larger!

Transcript 0:00 it's been almost four months now without 0:02 a single clear night here in washington 0:04 and obviously that doesn't give me a lot 0:05 of chance to do astrophotography which 0:07 is why i haven't really been too active 0:09 here on youtube lately hopefully you've 0:11 had some clear nights where you're at 0:12 and you've been getting some great shots 0:14 in the meantime though i've been doing a 0:15 lot of research on some different topics 0:17 these last few months and one of the 0:19 most interesting was just some basic 0:21 geology and geography and that's going 0:23 to be the focus of our video today i 0:26 wanted to show you some of the amazing 0:27 landscapes here with the help of this 0:30 map from the usgs this is their national 0:33 map viewer i think i'll have a link for 0:35 in the video description below if you 0:36 want to follow along but with the help 0:38 of their elevation tinted hill shade 0:41 try saying that three times fast this 0:43 allows us to really see the underlying 0:45 landscapes that would otherwise be 0:47 obscured by foliage and vegetation and 0:50 buildings and all that and once you 0:51 start to understand how much the planet 0:54 has changed especially in the last 15 0:56 000 years this brings a whole new 0:58 dimension to what you're looking at with 1:00 that said i'd highly recommend you spend 1:03 some time if you're interested in this 1:04 kind of thing looking up randall carlson 1:07 on youtube he's kind of the leader in 1:09 this field and he's got a lot of really 1:11 detailed videos probably 100 hours worth 1:14 here on youtube at least that gets into 1:16 the really important details of 1:18 everything we're going to look at today 1:19 in this video though i just want to 1:21 focus on the basic things we can 1:22 actually see here in the map as you'll 1:24 start to notice you don't need to have a 1:25 degree in geology or geography to see 1:28 what's going on here and the key thing 1:30 you want to keep in mind as we're 1:31 looking at the map is that all of these 1:33 landscapes were radically altered 1:35 between about 15 to 10 000 years ago 1:38 during this time frame the global 1:40 climate got both considerably warmer and 1:42 then considerably colder and warmer 1:44 again indicating multiple catastrophic 1:47 events again i would refer you to 1:49 randall carlson's videos for more 1:51 information but essentially what 1:52 happened is that 1:54 about 12 000 13 000 years ago 1:57 all of canada practically was covered in 2:01 over a mile thick of ice in some spots 2:03 almost two miles thick of ice and all of 2:06 that ice melted fairly rapidly due to 2:08 some type of global cataclysm 2:11 some people are saying it's a comet 2:12 which would make a lot of sense others 2:14 think it has something to do with the 2:16 sun 2:16 i would argue it's probably both based 2:18 on the evidence so far and as you're 2:20 going to see here we can actually see 2:22 the effects of this catastrophic climate 2:25 change just by looking at the map 2:27 i'd also recommend checking out the 2:29 comet research group's website that 2:30 we're looking at now they've got a lot 2:32 of cogent information here that really 2:34 explains the whole comet impact theory 2:37 and it really is a great starting point 2:39 for your own research 2:54 [Music] 2:56 anyway now would be a good time to get 2:57 back to the map i'll just start with 2:59 some areas that i'm actually familiar 3:00 with having lived in them and traveled 3:02 through them over the years and one of 3:04 the most popular is the one that randall 3:06 really focuses on in fact we did a 3:08 workshop with him in september we went 3:10 out to the scab lands and he showed us 3:11 around and we got to see these 3:13 landscapes in person the footage you're 3:15 watching now was captured by two of the 3:17 guys on our trip milo and casey and i'd 3:19 highly recommend watching their video if 3:21 you want to learn more about these 3:22 landscapes we can see right here we're 3:24 in 3:25 the border of washington up here in 3:27 oregon down here we have what's called 3:29 wallula gap 3:30 the green is the more depressed area 3:33 which means there was a lot of erosion 3:34 there and this was all caused by the 3:36 massive flood waters coming off of the 3:39 melting ice sheets up in canada this 3:42 video we're watching now is one of the 3:44 best examples to showcase the scale of 3:47 these floods 3:48 and if you go through and read some of 3:49 the native american myths from this 3:51 region they all talk about this massive 3:53 wall of water and these floods and this 3:56 gives you the perfect context for what 3:58 they're talking about 4:04 [Music] 4:05 and you have to keep in mind that this 4:07 water is filled with sediment and rocks 4:09 and boulders and trees and even massive 4:12 icebergs carrying boulders with them and 4:15 all this stuff reaches this narrow 4:17 little constriction the water starts to 4:19 back up and pond and that's what we see 4:21 over here and also out over this way 4:26 then 4:27 as it pulsed through this narrow little 4:29 gap it continued down the columbia river 4:31 gorge all the way out to the pacific 4:33 ocean near astoria in fact there was so 4:36 much water coming through here 4:38 that this whole region here down to 4:40 eugene 4:42 was kind of like a back flood so he had 4:44 so much water just pulled all the way 4:46 down to here and then eventually went 4:49 out 4:49 believe it or not they even found a 4:51 chunk of a meteorite in the willamette 4:53 valley that we just looked at and as 4:55 they mentioned 4:56 on wikipedia which i'm not saying is 4:58 reliable but they say right here that it 5:00 is the largest meteorite found in the 5:02 united states there was no impact crater 5:04 at the site which led them to believe 5:06 that the meteorite landed in canada or 5:09 montana and was transported as a glacial 5:11 erratic during the missoula floods at 5:13 the end of the last ice age just as we 5:15 talked about as you're starting to 5:17 visualize all this in your mind you can 5:19 imagine that there's millions of 5:21 icebergs floating on these flood waters 5:23 and inside of these icebergs some have 5:25 large boulders and in this case a 5:27 meteorite 5:29 this video here was taken in new 5:30 hampshire and i thought it was a great 5:32 visual in regards to the wallula gap 5:34 floods because at woolula gap that's 5:37 where a lot of the water got stuck at 5:38 and began to back up so this is a great 5:41 visual to show you how when the water is 5:43 filled with ice 5:45 not to mention the trees and rocks and 5:46 icebergs and all that it really 5:48 changes the dynamics of those floods and 5:52 this just helps to give you a sense of 5:54 scale 5:55 if we look at this video here 5:57 this also reveals an important point 6:00 when that narrow gap got constricted and 6:03 filled with icebergs and rocks and trees 6:06 eventually the pressure got so intense 6:08 that the floods started to back up and 6:10 go in the reverse direction 6:12 there's actually stratigraphic proof 6:15 that shows that this happened during 6:17 those ice age floods the current of the 6:19 rivers reversed because there is so much 6:22 water trying to get through a narrow 6:23 area 6:24 and then as these icebergs and rocks and 6:26 trees get forced through that gap every 6:28 so often the water gushes down 6:31 these floods clear out a little bit but 6:33 then there's another constriction and 6:35 this keeps happening over and over again 6:37 which leaves us a lot of really 6:38 interesting evidence throughout the scab 6:40 lands 6:42 if we follow these 6:44 original features further north we can 6:46 see that they tend to go straight up 6:48 into canada 6:50 and this is an area where we have this 6:52 confrontation between the more 6:55 uniformitarian mindset and the 6:57 catastrophist mindset the current 6:59 mainstream theory is that all of the 7:01 erosion we're seeing in the channel scab 7:03 lands was caused by glacial lake 7:05 missoula catastrophically flooding out 7:08 what they say is that glacial lake 7:09 missoula would fill up with water in 7:11 fact so much water that would be the 7:13 size of lake erie and lake ontario 7:15 combined just to give you some idea and 7:17 when all this water would fill up it 7:19 would get stuck at the purcell trench 7:20 load near sandpoint idaho eventually the 7:23 pressure would become so strong that it 7:24 would burst through the ice dam and then 7:26 flood out through the scab lands and 7:28 cause all the erosion and the main 7:29 reason they came up with this idea is 7:31 because we can see similar events 7:32 happening in iceland today but there's 7:34 two big problems with this theory the 7:36 first is that they're saying this event 7:38 happened over 40 times in a row in the 7:41 span of a few thousand years that means 7:43 glacier lake missoula would have to fill 7:45 all the way up the ice dam would come 7:47 down block it off it would burst through 7:50 the ice dam is now gone the lake drains 7:53 the lake fills up again 7:55 the ice dam reforms and this just 7:57 happens over and over and over again and 7:59 when you look through the climate 8:00 history and just look at the physics it 8:02 doesn't make a lot of sense the other 8:04 problem is that they tend to ignore all 8:06 of these ice sheets north of the scab 8:09 lands for some reason and they still 8:11 attribute all of this erosion for the 8:12 most part to glacial lake missoula not 8:15 the ice sheets due north of it melting 8:16 and catastrophically flooding out and 8:18 this is why this map is so great because 8:20 we can see with our own eyes that 8:22 there's all these mountain valleys that 8:24 must have been filled with melting water 8:26 and ice pouring down into the scab lands 8:28 if we trace all of these valleys back to 8:30 their central location we find a very 8:32 odd flattened out area in the midst of 8:34 the rockies this is where prince george 8:37 is at today and this would lead us to 8:38 believe that maybe something happened 8:40 here during the ice age 8:42 therefore the logical assumption would 8:44 be that there was some maybe some sort 8:46 of impact right here into the ice sheets 8:48 and again you can imagine if there's a 8:50 mild thing of ice you're not going to 8:51 have a big crater beneath that 8:52 necessarily as the ice would absorb most 8:54 of that impact and then melt 8:57 and this is one of the things that 8:58 randall has spent the last 20 years 8:59 investigating and trying to find 9:01 evidence that would suggest that a lot 9:04 of these scab-lance floods started up 9:06 near prince george getting stuck at 9:08 certain points and creating these 9:10 massive ponds 9:11 and then flowing out to the pacific 9:14 ocean 9:15 another interesting side note is that 9:16 the channeled scab lands we've been 9:18 talking about here is mainly composed of 9:21 basalt this basalt was extruded from the 9:23 earth i think 16 to 10 million years ago 9:26 somewhere in that range and that alone 9:28 is mind-boggling because as you're 9:30 driving through these landscapes you're 9:31 seeing the erosion but it's happening on 9:33 top of this really hard volcanic rock 9:36 that's just piled for hundreds if not 9:38 thousands of feet high it's really hard 9:40 to comprehend what you're seeing 9:43 and that leads me to an interesting 9:44 theory about how the yellowstone super 9:46 volcano formed one of the leading 9:48 theories that i've heard is that the 9:50 yellowstone caldera was caused millions 9:53 of years ago by a very high energy 9:55 impact with an asteroid this asteroid 9:57 must have been very dense and moving at 9:59 a really high speed just straight into 10:01 the earth think of it like getting shot 10:03 with a rifle then as the earth began to 10:06 bleed from this wound it was extruding 10:08 all this magma through this region right 10:10 here in southern idaho speaking of which 10:13 the craters of the moon national 10:15 monument is a great place to stop if you 10:17 are traveling through southern idaho 10:20 and essentially what happened is after 10:21 our earth got shot by this asteroid if 10:24 you will 10:25 the continental crust moved very slowly 10:27 over millions of years and that left 10:29 this scar right here the wound itself i 10:32 don't think is technically moved because 10:33 it's part of the lower portion of the 10:35 earth and now it resides under 10:37 yellowstone and that's what all that 10:39 talk about the super volcano blowing up 10:41 could relate to is that it had its 10:43 origins and another catastrophic impact 10:46 that's just one interesting theory that 10:47 i've heard that explains this feature 10:49 right here 10:51 and right now we're looking at something 10:52 that most people couldn't even conceive 10:54 of the power of this one singular event 10:56 and all the erosion it's caused in this 10:58 little corner of northwestern america 11:02 and southwestern canada but if we 11:05 go over here 11:06 we'll see similar original features 11:09 you know if you've ever been to a stream 11:11 or the beach 11:12 you can almost start to see how the 11:14 water just came pouring down these 11:16 valleys and carved these immense 11:19 channels that nowadays we can't even see 11:21 without the help of maps like this 11:24 and in this region they had what was 11:26 called glacial lake agassi which again 11:29 if i'm not mistaken was basically a 11:31 giant melt water 11:32 pond at one point or another that 11:35 drained out ultimately down through the 11:37 mississippi river 11:39 which 11:40 really seemed to have taken most of the 11:42 flooding from central 11:44 and eastern united states and of course 11:46 up into canada and if we zoom in here 11:48 you can see things a bit better just all 11:50 the different flood channels coming down 11:53 converging on the mississippi river and 11:55 then pouring out into the gulf of mexico 11:57 another thing to keep in mind is that 11:59 we're only seeing the most recent events 12:01 because if you're going to have a 12:02 massive flood like this 12:04 on a continent-wide scale it's going to 12:06 completely obliterate 12:08 a lot of the previous 12:11 features of the landscape just from the 12:13 sheer erosion if we go to the 12:15 adirondacks up here which is a great 12:17 place to explore we can also see that 12:20 there is clearly a lot of water flowing 12:22 through what is now lake champlain 12:24 another factor to consider is isostasy 12:27 this is when you have miles of ice 12:30 pressing down on the earth the ice melts 12:32 and now the earth is rebounding and 12:34 actually rising in elevation 12:37 this would also affect how the water was 12:40 moving in and out during these chaotic 12:42 times 12:43 also the finger lakes which are well 12:45 known 12:46 these 12:47 were potentially caused by if you 12:50 imagine you had the ice sheet kind of 12:52 ending right here and then you would 12:54 have these very high pressure 12:56 sub-glacial flows underneath the ice and 12:59 this would over time carve out those 13:01 finger lakes 13:03 in fact just north of the finger lakes 13:06 we have what are called drumlands and 13:08 these are a pretty 13:10 interesting erosional feature the 13:13 drumlins indicate that again this was 13:16 all under the ice and as the water was 13:19 flowing underneath the glaciers it was 13:21 subject to very high pressure and it 13:24 caused these really interesting 13:25 landforms that are still visible today 13:27 with the help of these maps 13:29 and we see almost identical drumlands 13:31 over near where i'm living now in 13:33 washington 13:34 notice how they just kind of fill up 13:36 this whole area and give us an idea of 13:38 where the southern edge of the ice 13:40 sheets used to be so here's the drumlins 13:43 in new york let's take a look at them 13:45 over in washington next right now we're 13:47 looking at the puget sound area 13:49 seattle's up over here olympia would be 13:52 down here tacoma 13:54 and the drumlins here aren't as 13:56 noticeable i guess you could say but 13:57 when we get a little bit better 13:58 resolution we'll be able to see that 14:00 this whole area shows these vertical 14:02 streaks which again are the drumlins 14:05 associated with really high pressure 14:07 water running underneath the glaciers 14:09 and in fact this whole area really 14:11 showcases what happened 14:14 again about 12 000 to 11 000 years ago 14:17 with that catastrophic melting another 14:19 thing you want to keep in mind is that 14:21 sea levels were 400 feet lower 14:24 during the ice age and the reason for 14:26 that is because a lot of the water was 14:27 locked up in these gigantic ice sheets 14:30 covering canada as those miles and miles 14:32 of ice melted that was enough to raise 14:34 global sea level about 400 feet in a 14:37 surprisingly short amount of time 14:40 and we can't forget about the ice sheets 14:42 in northern europe there's a lot of 14:44 evidence that shows that these 14:45 catastrophically melted as well probably 14:48 during the same time frame 14:51 [Music] 14:58 we're jumping around again this time 15:01 we're in the border of arizona and utah 15:04 we have the grand canyon right here 15:06 and this is arguably one of the most 15:08 interesting areas to notice the erosion 15:10 if you know what you're looking at i did 15:12 another workshop with randall in may and 15:14 this was a southwestern trip and we went 15:17 from flagstaff arizona all the way up to 15:20 moab and back and along the way we saw 15:23 really clear evidence of massive 15:25 rainfall that scoured this desert 15:27 landscape 15:28 most likely around the time of the 15:30 younger dryas 15:32 it doesn't show up too well here on the 15:34 tinted hillshade map 15:36 but i'll probably do a separate video if 15:38 anybody's interested where i show you 15:40 the photographic and google map evidence 15:42 that really drives home these points of 15:45 just unfathomable rainfall in the desert 15:48 of course 12 000 years ago the climate 15:50 of the southwest was probably quite a 15:52 bit different than it is today 15:54 and if we go up into canada 15:56 we can see the final remains of the 15:59 flooding as the ice sheets melted away 16:01 again we have these streamlined 16:03 erosional features but these are massive 16:05 you know this isn't just some little 16:06 thing at the beach these are just really 16:08 huge 16:09 areas of canada 16:11 just completely stripped through and 16:13 nobody would have any idea because now 16:14 it's just covered in forests and 16:15 prairies and plains and you can't really 16:17 make sense of it unless you see it with 16:19 the tinted hill shade which is another 16:20 nice benefit of our modern technology 16:22 even up over here we can see 16:25 the remains of these flood areas 16:27 reaching out 16:29 and just taking out everything along 16:31 with it i think it's pretty obvious that 16:33 we had multiple catastrophic events 16:35 happen from the balling allorod to the 16:37 younger driest and all the evidence 16:39 backs that up from a mass extinction of 16:42 animals across the globe 16:44 to sea levels rising 400 feet 16:47 to the 16:48 mile thick ice sheets across all of 16:50 canada melting within just a few hundred 16:52 years clearly that's going to have some 16:54 impacts on the planet and the erosion 16:57 that we see here would obviously tie 16:58 right into that 17:00 but that's really all i wanted to talk 17:01 about today i really just wanted to let 17:03 you guys know this resource is here 17:04 because i personally think it's 17:05 fascinating just come in here 17:07 and spend however long you want just 17:09 looking at all the erosion maybe where 17:11 you live and get an idea of what might 17:12 have happened during these chaotic times 17:15 and if you want to learn more about this 17:17 i'll have links to randall carlson's 17:18 page he's really the the main guy 17:20 talking about this from what i've seen 17:21 and he does a really good job of laying 17:23 it all out well i hope you guys enjoyed 17:25 this radically different video and i 17:27 might do one or two more videos if you 17:29 guys are interested showing you some of 17:31 my photos that i've taken living on the 17:33 road the last few years and now that i 17:34 have some more context to put these 17:37 really cool landscapes of the southwest 17:39 in with the global changes that we've 17:42 experienced within the last 15 000 years 17:45 so thanks for watching and i'll see you 17:47 guys hopefully in another video 17:50 [Music] 18:02 [Music] 18:10 [Music] 18:32 you
I haven't watched this yet, btw.
Thank you for posting the transcript.

At first I thought these were Bible verses.

How many cats constitute a catastrophe?
I have traversed the scablands from the Wallula Gap to the Grand Coulee Dam, and everything I have seen fits the basic narrative of megafloods. The details of the theory will no doubt be refined over time, but the basic thesis appears undeniable. Anyone who doubts the possibility of a Great Flood of Biblical proportion, just pay a visit to eastern Washington state.
Me too, I did some of the same hikes.
The channeled scablands were formed by the failure of an ice dam that released a huge meltwater glacial lake. It wasn’t a worldwide event.
I think a catastrophe is actually a punctuation mark invented by and used by cats when they’re writing messages to each other as they bury their, uh, business.
I am aware, just not interested in using it.
