Naoaki, thanks for watching. Glad you enjoy these videos. Look for more this spring.

Such a fascinating history of just how so many different ages and orgins of rocks from sandy beaches and deep earth mantle to ancient ocean beds ended up layered together in a modern day escarpment. Quite a history!

I drove California across the salt flats to the mountains many years ago. The colder temperatures felt like a luxury after the seemly endless desert. Thanks for the video.

Wow another fabulous rock story… in your geological wonderland.. I love how rocks tell you what happened to them thank you Shawn

I am now an unrepentant binger of your videos, Shawn. You're my adopted geology prof and helping make up for decades of lost time learning about good old Mother Earth and how she works geologically. Thanks a million.

Very interesting series. I live in the far North of Scotland, so I don't know the areas you describe, but this video resonated with me. I live close to the Moine thrust, which was created in a very similar way. Thanks for these videos, they are fascinating.

Awesome! I took my class there in 2016. We visited the Moine thrust at Knockan Crag. Amazing geology in Scotland and hope to return someday.

Thanks Doc, I follow everything you do, ride around Idaho with your book. I'm linking to this video to help my wife understand her little brick house that sits on this fault. We were cutting a ginormous hole in the middle of the back wall of her house, and I needed the geological skinny on the big picture, and it turns out, it's this. I marvel at how you can rattle off rock types and layers without breaking the syntax of the english language . Just another caveman trying to understand his world....your fellow Idahoan....

I solved this puzzle a while back. I've now solved the globe since I've found the key works to unlock all the mysteries. I need someone like Shawn to see it, and then take me to your leaders! lol I feel like an alien with this knowledge. I really think a mentor representative would be perfect to knock on some heavy doors and say "I think it'd be a good idea if you listened, this guys nuts but I think he's got something BIG". First one to bring this out will be getting the interviews!

Wow! What a view. I’d love to be up there! Thank you for sharing all of this wonderful scenery and amazing geology. (And it’s literally wonderful-full 😮😊)

My husband’s family had a home with a fantastic view of Willard Peak for many years and we could see it from their yard. Little did we know how interesting that peak really was. I’m loving these videos. Geology was the only science class besides environmental science that I ever enjoyed in school and college. Now I’m remembering why.

Could you do a video about the strange geology of the Wasatch Front in Provo from Rock Canyon to and then up through Provo Canyon? This part of the Front is uptilted from the mouth of Provo Canyon and rises at a strange angle all of the way to the north side of Rock Canyon. As you drive east from the mouth of Provo Canyon there is serious warping and folding of the sedimentary layers on the right hand side of the canyon which are part of the strange uptilted layers lying north to south seen from there to Rock Canyon. Thanks.

@@monicacall7532 Thanks for watching and I love the suggestion. The rocks along the Wasatch between Provo and Rock canyons are tilted to the east due to the uplift along the Wasatch fault which runs along the base of the range. The folding of the rocks you see in Provo and Rock canyons are due to the Sevier Orogeny, a mountain building event that occurred around 140-100 million years ago. It was caused by plate collisions to the west which compressed the existing rocks into folds and also shoved slabs of rocks over the top of each other to create thrust faults. Both canyons have some really awesome features to showcase. I will see if I can get out there this summer.

Great information I will never look at those the same

That is the trickiest thing to figure out. Because the land can rise from great depths sometimes the deepest oldest material ends up at the top of the mountain. Like being buried standing up but over time you end up above ground and in a reclining position with feet higher than your head. And you may be leaning to one side as well. Nothing on earth stays where its at forever.

I would have paid more attention to geology if my teacher was as interesting, intelligent and engaging as Mr Shawn Willsey. That was fifty years ago, so, what can one expect. Many teachers taught more than one subject.

Beautiful view. Must have been a good walk, a good day for it too. Excellent explanation given of formation and rock types. How is it that the Limestone is almost black ?

It was a pretty big hike (~18 miles) as I was training for a Grand Canyon rim to rim hike later that year. Thanks for your kind words and viewership. I believe the color of the limestone may be related to the carbon (organic) content.

Thank you for the wonderful video! Loved hearing the history of how these mountains formed and their original formation locations. You being on location pointing it out really makes it.

Thanks for pointing out many interesting features of Ogden canyon. I visited my son who was living there several years and we drove through the canyon and on several roads in the area of the Wasatch Mts. It is a beautiful area. We didn't stop to see the Z fold, so what I saw was more of a 7 fold ad we drove by. Thank for the cartoon drawings to show exactly what happened to create the fascinating geology of the area. I live in the hill country of Tx which is all limestone, so not a good place for collecting rocks but great for fossils.

Great video, Shawn

My great, great uncle actually located the silver king in park city, he sold it for a shot of whiskey, I am told. It might have been a whole bottle, when he woke up after getting totally sloshed he was no longer allowed near the mine (it wasn't a mine then but merely a located source), lest he be shot on sight. He couldn't complain because he wasn't in the "in" crowd of that era. A little trivia. Oh also, he was the adopted son/brother in law of Joseph Stacey Murdock.

Please do a video on the Riggins, Idaho area where the X plate has been diving under the Y plate, or whatever. Occasionally I see a geology class looking at something along the Salmon River canyon, and I get out of my car and ask them a question. They never seem sure about the answer. Edit: OK, I see you did a Salmon River float trip video. Watching that one now.

As I have traveled in Utah it seemed to me that the mountains were uplifted. The severe orogeny I have heard of and is on my study list. I found the layers and ages of the rocks interesting. It struck me that the forces to lift layers above younger layers had to be immense. I wondered at first that the sea you talked about might be an inland sea. But at the edge I think it must have been ocean. Which would it be?

Thanks for watching. BCC has some great geology. What are you most interested in? The story of the rocks or how the canyon formed?

Thanks for the video, I have always wondered how the straight rock lines were formed that are very evident in the first few seconds of your video. Do you know? These lines are also very evident on satellite images around Ben Lomond.

@shawnwillsey

2 жыл бұрын

Great question. Are you referring to the nearly horizontal lines you see near the summit of Ben Lomond? If so, these are one of two features. 1) the bedding, or deposition layers of the sedimentary rocks (mostly limestone and quartzite from the Cambrian period, about 530 million years ago). 2) thrust faults that divide the units. These are what I talk about in the video. The rocks get repeated as slices are shoved over the top of younger rock layers due to compression during the Sevier Orogeny (a mountain building event) about 130-80 million years ago. These mountains are now long gone. Hope this helps. If I missed the intent of your question, please let me know.

I think the Wasatch Front is primarily a Laramide feature that has been modified by extension, not the direct result of the Sevier orogeny. It may very well be that the overthrusting you show occurred during the Sevier orogeny, but the modern Wasatch is an extensional Basin and Range feature, with normal faulting, not low-angle thrust faults. I just wanted to make it clear that the Wasatch Front itself is not a Cretaceous Sevier orogeny feature, but a more recent phenomenon.

@shawnwillsey

Жыл бұрын

Most Laramide structures are further east. Sevier Orogeny is the main player in this part of Utah. Modern Wasatch are a result of Basin and Range extension as you point out.

I'm really fascinated by Utah's geology/geography and found this video really informative. Can you recommend any good books that focus on Utah?
