Thank you. I was looking for a straight forward explanation of what a coulee is and this is it.

Thanks for watching, Michael! Yes, some of the material off the coast of Oregon was deposited by the Ice Age Floods....but much of the big stuff (blocks of broken columns) were dropped in piles just a few miles downstream in places where the water slowed.

Good question. The basalt was carried downstream - sometimes just a few miles and dropped when the water slowed....sometimes all the way to the Columbia River Gorge and beyond!

Just had a discussions of coulees with at woman from Louisiana. What she called a coulee, I would call a slough. Now I find there is a technical geological meaning as well. My brother was born in Grand Coulee. Those French Canadians throwing their words around.

Another good job by the hip dude.

Your explanation is as good today as it was eight years ago when you posted. I've been reading about Custer Nat'l Battlefield in Mont. and that terrain is full of coulees (e.g., Medicine Tail Coulee). If the shape is uniformly box-shaped, I suppose they are like the highways that get walled off on both sides to help sound proof (and sight-barrier proof) the adjacent residential neighborhoods that don't like having a highway running through them. Thanks for your vid.

I enjoy watching your videos and I learned something too.

Love the intro. Great information and keep up the good work. Subbed.

That was entertaining, concise and educational. 💚

Just discovered this channel today and loving it. Great little format with lots of information to at least to start researching into some of these very interesting subjects, I love geology form my younger days. I actually was just on Joe Rogan's podcast with guests Graham Hancock & Randall Carlson that as one of the subjects of the podcast was about these huge late era ice age and post Ice age floods in the extreme northwestern contiguous United States mainly here speaking of eastern Washington State. How about that for a connection? 😂👍🏽🤔🖖🏽👽🤘🏼🐙💪🏽🌎✌🏽

Glad we could help, delineater!

We miss you come back ❤

Thanks for the nice comments, Field Notes! I'll look for your channel....

You have the best videos on youtube

Hey fellow Geologist! I started a channel talking about my mishaps in Geology Field Camps, I'm sure we all remember some awkward/death defying times right? I love seeing other geology channels. Your video is very informational very nice!

This guy is a GEM!!

Just the best.

Thank you. Hello from Washington.

Thanks for the good question, Daniel. The Columbia River Basalts are a major reason for the coulee development - the lavas are thick and heavily fractured. Southern Idaho has basalt, but not like the CRB's. No thick lavas in central Canada either. Floods + CRBS = Coulees!

Very informative. I started enjoying geology and geography years ago. Lately I've been studying glacial lakes Lahontan and Bonneville along with Sierra Nevada glaciation. Did a similar effect to the coulee's occur upstream on the Snake river when Bonneville drained down it? Or for that matter on Lake Agassiz in central Canada? I haven't heard of coulee's forming from other ice age floods.

>^. .^< Simple Process in a large scale. Thank You

ive often wondered if some of the coulees such as rock lake may even reflect former lakes and river channels that had the weakest spots to be plucked and washed away with their clay and weak pellagonite you mention. sometimes i face clay and mixed up deposits and wonder if thats part of the reason the coulee behind my back is there. great videos when i think ive seen all of them i find more.

@Ellensburg44

Thanks for the feedback. Tough to speculate on former lakes and channels idea. Many floods hitting each area - going back to the earliest part of the Ice Age potentially. For water speeds, landforms have been carefully studied and math applied to features. I've seen nothing faster than 60 mph.

one other thing ive wondered if once a coulee is formed and getting bigger i wonder how high the speed of the water and boulders gets on impact into the plunge pools my guess is that i has to be 200 mph minimum i will start keeping my eyes peeled for shattered impact areas. most are maybe under water like dry falls

Again, vary informative and interesting. So, because of their contraction cooling cracks around each individual basalt column, the columns were made for easy disassembly, removal and clean up by the high speed voluminous melt and ice dam flows????

Interesting. I would imagine the repetitive nature of the floods had an effect as well - Bonneville only drained the once as far as we know while the Missoula floods may have occurred dozens of times. Agassiz did drain on multiple occasions but in different directions and across very different terrain (aka McKenzie river, Hudson bay etc...) Thank you. Do you know of anywhere else on earth that has produced similar terrain to the Washington Coulee's? I might enjoy some "light" reading. :-)

Later in life, I realize now I should have been a geologist. In a way I think many of us are, such as when we go on hikes or drives to view and appreciate mother nature’s magnificent creations.

First, thank you for the excellent video! Planning a Wisconsin trip that seems to go from "This Coulee" to "That Coulee". I thought it must be a family name, lol!! Are those coulees formed the same way as the ones you showed in Washington? Thanks for any response.

As I am sure you have realized by now, they aren't. We essentially call all valleys into the bluffs "coulees". Had no idea it was a regional thing until I was 25.

Totally.

Are the coulees of North & South Dakota formed the same way? Around the battle site of the Little Big Horn there's coulees also. Or am I wrong?

So I've noticed that in many of these Coulees there are lakes. Yet I don't see ( looking down with Google Earth) any sources of flowing water. Did the floods erode enough bedrock that springs were formed and that is what the source of water is?

@Ellensburg44

Yes, most coulees do not have rivers. The lakes are sometimes fed by groundwater seeps....and sometimes artificial (irrigation runoff).

The coulees in Washington State resulted, I gather, from the confluence of two historical evelts, the 15-miillion-year-old flood basalts, and the more recent Ice Age floods. That makes me wonder whether there are coulees anywhere else on Earth, and whether equivalent historical events elsewhere could have set the stage for coulee production. It strikes me as unlikely. I also wonder where the word "coulee" came from. If the Washington coulees are unique on Earth, then is coulee an Indian word?

Thanks! Funny I've never known the definition of Coulee before; I always thought it was just the name of a city. Can you tell me where all the basalt went? All that material should be somewhere now right?

@Ellensburg44

Much of the material traveled just a few miles and was dropped when the floodwater slowed. Basalt boulder piles. Some of it made it much farther downstream.

so, where did all of the basalt GOE? Are there piles of basalt rock somewhere in southern Washington , Northern Oregon?

@Ellensburg44

Good question, Johnathan. The basalt blocks were dropped anyplace the water slowed temporarily. Piles of basalt near Ephrata, Mattawa, etc in Washington...and more piles in the Columbia River Gorge upstream from Portland, Oregon. Thanks for watching.

What about the Coulee in the Driftless Area of Wisconsin? There was no glacier....

Do you believe in twin landscapes? These Coulees in US are very similar to a place called “Fecho da Serra”, in Minas Gerais State in Brazil, where I have a property .

Where did all that rock go? Where did it pile up?

Are there debris flows off the coast of Oregon that are built by the carried off basalt columns?

Basalt definitely is not created by volcanoes. Call me crazy if you want but those columns are clearly something else. Looks more biological. I came looking for answers but that’s not it

They're formed by the same things contorting the landscape in Iceland -- flood basalts rising up from _fissures._ Big ones. and lots of them. And lots of separate events over a million or so years -- perhaps 16 million years ago. www.usgs.gov/observatories/cascades-volcano-observatory/columbia-river-basalt-group-stretches-oregon-idaho
