Which confirmed the existence of glacial lake Missoula. The first guy to propose it was ridiculed until another geologist did the homework by Missoula to explain the large influx of water all at once. That was in the lecture! So fun. Well part of it, the OG being ridiculed is new info to me, thanks. Link to comment Share on other sites More sharing options...

I was already in love with the PNW but this episode sent me out exploring! Link to comment Share on other sites More sharing options...

How Pardee figured out the ripple marks without an aerial view is amazing. They feared Bretz was talking about a biblical flood idea. Could have been up to 36 separate floods. Much like Plate tectonics there was a hole in the original hypothesis that left too much unexplained. I have shown this video in my HS geology class btw.

AztecAlien Posted December 4, 2021 Share Posted December 4, 2021 I used to be rock hound. They fascinated me. But then, someone stole my idea of the pet rock and I lost interest. Link to comment Share on other sites More sharing options...
mysfit Posted December 4, 2021 Share Posted December 4, 2021 Check for Rockhounding books on Amazon. They are out by state and have naps to sites with descriptions. Also Roadside Geology books by state. There's jasper just SW of here, opal over the border in Nevada. Lots of good stuff in Nevada. Old mine with Fluorite north of the Berlin-Icthyasaurus park. Lots of agata and jasper. One of the Final Five.......... Link to comment Share on other sites More sharing options...
mysfit Posted December 4, 2021 Share Posted December 4, 2021 Found this just south of the fluorite mine. Sucker weighs more than a 20# bag of cat litter. More than a foot across. You have NO IDEA how long it took me to drag that sucker a half mile to my truck. One of the Final Five.......... Link to comment Share on other sites More sharing options...
