I grew up in and around these formations and mines. I just learned more about them in the last 4 mins than I ever knew about them in the last 40+ years. Thank-you!

@@shawnwillsey Careful what you ask for. ;) South of Oakley is a beautiful range, with a white tuff layer on the bottom, several orange basalts on top of it, capped with a dark red that is several hundred feet. Theres even a thin layer of a purple basalt. Coal Banks Creek, off of Goose Creek, is a great place to observe it. Nearer you is Thousand Springs, bubbling right out of the basalt. I'd love to hear the story on that. To the East one of my favorite osidians comes from Malad. There are large pumice hills there that are mined for abrasives in modern household items. Further east still is Lava Hot Springs and Soda Springs, both related to the basalts in the area I'm sure.

All of your videos are just great, Shawn. Thank you so much.

Informative vid as always. Idaho is such a cool state. Unmatched geology

Yay I knew they were metamorphic rocks… yes… learning and understanding.. thank you so much Shawn

You ought to go a bit south and check out the Ashbrook Mining district. There are three fault zones that converge in the area which makes it interesting to see the changes from one zone to the next. These faults do creep constantly. Every spring when the mine reopened they had to be cleared out from the rock falls from the earth movements.

Nice video! I’m from Southeastern Idaho and am happy to learn more about the geography there.

Over on the dirt road east of COR’s there is a turn off that passes a sign for Utah border, goes into National Forest with some amazing Quartzite outcrops.

Thank you so much! This is the information I was looking for. Amazing!

I wanted to let you know that, coincidentally, I listened to a podcast (Next Up! Mid-Century Homes, episode 20) interview with the owner of a Frank Lloyd Wright designed house, Archie Teater Studio (Teater's Knoll), beside the Snake River on Hwy. 30, northwest of Twin Falls, Idaho. The house was beautifully constructed with Oakley Stone.

Hey, I know that house well. I am an avid whitewater rafter and we often run the Snake River right past this house. The rapid just below it is called Frank Lloyd Wright rapid. It's a really awesome house. Wish I could see the inside sometime.

It's a year later and I just ran across you channel. It's wonderful to have an understanding of what I've looked at all my life. I love Oakley rock.

Nice presentation. There are also more stone mines/quarries way up north a couple miles from the Montana frontier on Hwy 200. Also quartzite.

Love your informative and get right to the point vids, thank you! Just ordered your second edition Idaho Roadside geo book recommenced to me by my favorite local geo professor Andy Buddington!

Awesome. Thanks for the kind words, watching, and picking up the book. Andy is a great guy and super dedicated teacher. You are in good hands. Look for more videos soon. I am heading to southern Utah and norther Arizona this week.

What is the story on the green stones you find in the stone yards in Oakley. So far I have only had the shiny flag stone on my truck and I'm curious about the other rocks in the area.

It's a chromium-rich mica mineral in some of the quartzite known as fuchsite.

best comment ever!

So if it’s muscovite, is it splitting on original bedding planes, or metamorphic foliation? Or is it such that compression was normal to the bedding planes in this case and the foliation lines up with the bedding planes and enhanced the “flaggy” parting of the stone?

@shawnwillsey

Жыл бұрын

Hi Avana. The rock is definitely splitting along bedding planes. The metamorphism may have been more due to burial and therefore heat rather than differential stress or uneven pressure.

Best geologist online (and probably offline as well).

@@michelleparks Ah, thanks for the clarification. The basalt (lava rock) at Hells Half Acre on I-15 is among the youngest in the state, about 2,000 years old. The basalt around Pocatello such as along the Portneuf River or at Ross Park is much older, about 430,000 years old. You can learn more about the geology of both areas and the whole state with a book I co-wrote, Roadside Geology of Idaho.
