- The area areound the Alta Ski Resort in the upper part of Little Cottonwood Canyon of the Wasatch Range of northern Utah displays awesome glacial landforms as well as some great mining history. Check out one of several mine sites and the unique rocks in the area with Shawn Willsey, geology professor.
I appreciate a short engaging video with a small number of takeaways to balance my geo fix against the longer technical presentations. I like how they expose me to different areas. Keep 'em coming.
I sure enjoy your traveling geologist series. Your passion for the profession is inspiring.
Thank you. These are fun to do and I love to share what I know and love.
I used to live and work at a restaurant just behind the ridge in your foreground in 1982-1983. Just at the base of the Supreme and Sugarloaf chairlifts. It was called the Alpenglow back then, but it appears to have been rebuilt and renamed since then. Something like $300/month plus room and board plus a season pass. The best part was all the avalanche mornings closing the road from SLC causing business to be so slow, that the boss would let us take off and and ski all the virgin snow that would otherwise go to waste.
I believe the ridge you pointed out is Mt. Superior. The dark reddish rock is likely Cryogenian Mineral Fork Tillite. There are nice exposures of the tillite with dropstones in Albion Basin.
Yes. You know your geology well. The same unit is also exposed out on Antelope Island where it lies beneath a dolostone (cap carbonate) unit and is part of the Snowball Earth story.
Re watching this now from Albion basin. Great video as always
Awesome! Thank you! I need to make more Wasatch videos.
Beautiful! Thanks!
Shawn, great video bro. Would you by any chance have the GPS coordinates to the spot you were standing in? Lol. I lead all of the Field trips for the Wasatch Gem and mineral society. I would truly appreciate if you had coordinates to this site so we could head up there as a group and do some rock hounding! ❤🎉😅
Thanks for watching and learning with me. Check out my other existing videos and subscribe if you like the content. I think these coordinates are pretty close: 40.59621, -111.62115 Let me know if your group goes up there.
Awesome ,Thank you Brother 👍🏼❤️
Loved this, Shawn. The two Cottonwood canyons are so close but so different. It is hard to pick a favorite. The lower portion of Big Cottonwood is interesting around Storm Mountain and the S-curve section. Above Solitude and Brighton, there are some massive outcroppings. Would love to see you explore BCC the next time you're in the area. I'm impressed with the climb up to Lake Blanch as it seems that you literally climb through geologic time.
Yes. We have family in the area so more wasatch videos are planned.
Could you do a video on the mineralogy of The Oquirrh Mountains and the mountains down around Eureka, UT. I understand these were ancient volcanoes formed the mineral deposits?
Lived at the top of Big Cottonwood on other side of the ridge. What a treat! The glacier u shape doesn’t open up until miles up the road. It is very narrow and steep sided at the bottom.
What a great location. Lucky!
If you do come into the valley to do more Wasatch front coverage, let us know, we will sponsor your meals while you're here!
I think the Wasatch and Uinta should be the true Rocky Mountain National Park. Best gem in the nation imo.
I would not disagree. There is definitely enough amazing geology and scenery to justify it.
Uintahs are pretty incredible. Hiked short stretches of the Hi line trail several times.
Question: was there any surface volcanic activity associated with the little cottonwood granites?
To the east, around Park City there was surface volcanoes and volcanic rocks (Keetley volcanics).
Not sure if you're a skier, but that looks like Pyramid or Chad's gap.
