I taught basic Oregon geology at a MS level for years, primarily using Oregon's subduction/volcanic profile as the perfect example. Your bit about the Willamette Valley formation made perfect sense to this now lawman. Damn, son. Great stuff. Willamette Falls next!
@@BetterGeology OK so I am trying to find a basic and comprehensible description of the formation of The United States' second largest waterfall, willamette falls.
Don't forget to include in that story the Bretz flood impact. Huge deposits were brought in during those many floods. A great deal of the soils that were stripped away in Washington wound up as new deposits in the Willamette Valley.
Very true - I omitted that because at the time I made this video I opted to focus on the tectonic forces which created the Valley rather than the more recent river and flood impacts. It was already a broad floodplain before the Missoula Floods, they just helped out a bit! Obviously if I made this video today I would have included that.
@@BetterGeology Good videos. Thanks for taking the time to put them together. My career was as a soil scientist. Such a great career. I would do it all over again. Enjoy this great world around you. It tells us such incredible stories. The evidence is all around us. It is up to us to understand what the soils, geology, geomorphology, organisms, weather, climate, and time are 'telling' us. You are in for some great experiences.
By “another push”, I assume you mean a Cascadia “Big One” earthquake? If so, then there is no reason to expect Cascade eruptions as a result. Volcanoes can cause earthquakes, but earthquakes do not generally cause volcanoes to erupt (and when they do, it is because the volcano is already on its way to an eruption).
so wait, Wiki says that it was created by a series of ice-age floods that came from Lake Missoula. I know that wiki isn't always 100% accurate as its updated by its users, but are the accusations of floods completely false or is the WV's creation possibly a mix of the two?
Yak Cruisin Hi Yak- the Willamette Valley as a structure dates back hundreds of thousands (possibly several million) years, and has been filled by sediments from rivers and colossal floods in the eras since then. The Missoula Floods did indeed inundate the entire WV up to Eugene, but the valley already existed in nearly its present form before then. The floods left stuff behind, but did not carve the valley out of the mountains. Thanks for the comment!
You are correct. The reason is that I didn’t want to start talking about Canadian ice sheets and ice dams in Idaho in this short video just about the structural formation of the Willamette Valley. Besides, it’s another video I can do in more depth another time!
