This is great. I’m always curious about the few pockets of eastern oregon that weren’t covered by the basalt flows. The start of the Silvies River seems to be one of those places.
It's just on the other side of the Strawberry Mountains from where this was filmed, so it's headwaters are (largely) rhyolite and andesite flood lavas.
Good job kid. I'm very curious about the canyon walls surrounding "The Cove Palisades " state park just outside of Madras Oregon. How old? What are the layers made of? How much time does each layer represent? That kind of stuff. You're doing a great job, and I enjoy your videos.
There's a mix of rocks there. Further downstream (towards the dam) is a little bit of Columbia River Basalt (~16 million) on top of John Day Formation (~20-30 million). Upstream by The Island is mainly Deschutes Group, ancient volcanics, river sediments, and soils dating between 10 and 5 million mostly. There's a layer of basalt on top of that but I'm not sure how old it is offhand.
If I could have pursued geology in college, I would have. You gotta look up Nick Zentner from Central Washington University!! He has a bunch of presentations!
@@BetterGeology It is a very common error that people make when describing the movement of a glacier. Glaciers are in a state of advance. When the melting rate is greater than the advance rate, perhaps the phrase ablating glacier can be used.
Certainly true, but if I were to say “as the Strawberry glacier ablated” then 99% of my viewers wouldn’t know what that meant. Besides, the glaciologists I’ve worked with seemed to use both interchangeably. I’ll take the colloquialism 😃
@@BetterGeology I learned this in 1970 and it stuck to this day. The viewers will catch on if explained. At least it has the benefit of having the reader/listener accurately visualized what is really taking place.

Really interesting and informative. Thank you from England.
Thanks for watching!
I've been there before its absolutely beautiful
I love it there!
Incredible!!!! I can't wait to learn more about this area.
If only the rest of youtube was this concise and informative. Keep it up.
Thank you!
So interesting to see and you encourage me to visit the Eastern side of Oregon! I always enjoy your presentations and learn a lot,Thanks.
Thank you for watching! The Strawberrys are remote but worth every minute of the drive.
Great, as always! Really makes me miss Oregon! 🤙
Thanks!
So good. Love that underused area too. Thanks for the quick lesson.
Thank you!
@@BetterGeology We gotta make a video together one of these days.
Any time you like!

@@BetterGeology thank you
Is volcanologicly even a word?😂
Other than that, love Videos. My kids don't get why I get excited by ancient lava flows. The struggle is real 😂
Sure, why not!

Glaciers do not retreat.
What word would you use instead to describe the shrinking of a glacier?
