I lived most of my.lifr just a few miles from this feature, but didn't know it was there until a few mo the ago. Thanks Bruce, and Nick and Tom Foster for opening my eyes.
Superb explanation of a geologically very interesting part of the planet. I wish I had known about this geology back in 1988 when I travelled through this area on my way to Alaska. I live in Australia, a long way away but I appreciate the geology nevertheless. Thank you for posting.
There must have been a few early North Americans poking around at the edge of the glacier 14000 years ago. Imagine what they witnessed when a lake Missoula flood suddenly one day rushed over their village and entire world. The survivors on high ground must have been shocked at the spectacle. Maybe even suicidal. Beyond biblical in scale, sound and destruction. Talk about an emotionally scarring event.
it would be interesting to know, given that it's an accelerated melt of some kind, whether or not big old chunks of ice were part of the mix as it slurried down the canyons under gravity's constant pull. It might help knowing that it wasn't just mere liquid water, but hard, jagged chunks of icy stuff ripping through soft sandstone riverbeds along with the liquid. At the time it must've been one heck of a show. at the time, it must've been a very different world from the one we inhabit today. like, why did it flood here? why so often? what a beautiful mess.
Yes. Lots of ice-rafted exotic boulders strewn about along paths of the floods. These erratics are used to interpret locations and maximum elevation of outburst floodwaters.
Apparently all these videos were taken during the summer ( note small areas of green vegetation) what is it like during the winter? Is it high and dry, or does it receive a lot of snow?
Eastern Washington lies in the rain shadow of the Cascades so Western Washington (e.g. Seattle) gets the rain and Eastern Washington (e.g. Spokane) gets not so much.
I believe. In between 150'-250'.. But that's on a different clip. It's about 100 miles north of this area, if you're talking about 'Deep Lake'. That's near Grand Coulee. Thanks.

Don't forget Ned Zinger!
Fantastic! The drone footage and annotations are brilliant.
Fantastic. After flying by the canyon in a small plane, my curiosity was piqued by the resemblance to a furrow or corrugate. Now I know why. Thanks.
Best description and video yet on coulees. I considered myself far more educated now. Thanks.
Wonderful video of some magnificent geologic history. These are hidden gems of the PNW.
old but gold thanks
Some great shots there man, thanks for the video. This stuff is so amazing. The quantities of water required are just breathtaking.

Train Lord p
Awesome aerial views had me transfixed
Would have loved to ride that train so many years ago
This f-ing AWESOME!👍🏽 Thank you! 😊
Nicely done Bruce.
Fascinating, I would like to hike that trail thru the tunnels. Wonder why it was abandoned after so much expense.
Excellent

This film and graphics helps me understand the floods effects on the land.

Well done Bruce
*Thank you.*
More mind-melting monumentally massive landforms.
Love the illiteration!
Once again, thanks
This place looks like it could be on Mars, it's so desolate. Amazing what water can do when there's enough of it... or not enough, afterwards.
One giant flood did that and many tiny ones followed.
I’m surprised that no water flows through that canyon. It must be extremely dry there. Is there any farming in that area or is it too dry?
Catchment of the canyon is very small - explains why there is no surface water present.
Took a lot of water to do that damage!

its usually very cold and dry with the occasional 1ft snow storm.

Super, jak na Marsie :)
Thanks for watching!
Thanks Greg.
we should do some reforestation. that landscape got scraped clean.
Forests do not grow in the desert.
How deep is Deep Lake?
I believe. In between 150'-250'..
But that's on a different clip.
