"You have been watching Nick." Yes, Nick Zentner, really worth a look for anyone interested in Pacific Northwest Geology.

The Grande Ronde Valley in the Blue Mountains is a rift valley with an escarpment several thousand feet high. It's the 2nd largest fully enclosed Valley in the world.

I love that these people get together to discuss geology.

Enjoyed this very much! Thank you!

Amazing! Thank you for sharing!... altho I could have done without the dig sight starting at 10:25 with the gentle in the middle right, excavating a nostril and then eating its contents...

You should test triangle lake rock slides and see if it matches, and also billings/gold beach for Columbia river basalts. Triangle lake rock slides are lava flows that form a waterfall and water slides. Shotgun Creek bed is lava flow also and contains gold quartzite. Worth checking out.

Thanks for the informative talk :)

This is awesome! Thanks for sharing. 😁

Kula + Farallon motions = PNW clockwise rotation?

I still have a coffie can full of mt saint Helen's ash.

The title "Assembling Oregon" is clearly a homage to John McPhee.

Oregon is just America's version of Italy.. especially Northern Italy. They don't mention longitude and latitude that kind of stuff.. good video but they still have lots to learn.
