I've just watched Parts 1 & 2. It boggles my mind that you can go stand on rocks that have been around for over a billion years! Somewhat more boggling is that I'm starting to recognize and remember rock types and names thanks to your videos...😊
Wow, I took the afternoon off yesterday and was hiking there. Gotta take the opportunity before it gets hot (and the biting gnats take over the island).
This has blown me away. Rocks 1.8bn years old?... Wow! This reminds me of how I got into Geology 45+ years ago. We had an ex student visit my high school, who was studying the oldest rocks in Greenland, if not on Earth, as part of his PhD. He brought with him a piece of ancient sedimentary rock from the 'Isua Sequence' in South West Greenland 3.8bn years old. It was so gobsmacking to me that it inspired me into a life long interest in Geology. Just incredible that something so old exists, almost beyond comprehension. Keep up the great work Shawn and keep on inspiring future generations of rock bashers.
We're heading back to Utah for a visit in a few weeks, have been to Antelope a couple times, but your wonderful geology videos will bring a new appreciation of what we see there, as well as other Utah/Southwest spots we plan to visit. Keep up the great work, Shawn, your videos are a treasure. ❤ Sure will be interesting to see how much GSL has risen with all the snow.
Amazing! I finally know how to identify at least some rocks. Where I live (southern Québec), the rocks are a mix of glacial deposit just about everywhere thanks to the Laurentide ice sheet. It is really cool to 'hike' with you in such a rich rock environment like Utah. Thanks professor, those details of the crystals and texture that you give wonderfully help differentiate the rocks.
I really love your channel and videos. Really interesting stuff. I love rocks and love listening to someone who knows about rocks. Keep up the great content ❤
I find so much pegmatite, nearly everywhere I go around Vegas has it. My understanding is that lithium is found in pegmatite, hence the new lithium mine coming to the state.
Excellent follow-up of the identification series. I got gniess right. When I started the identification, that was just a word. Today, before you said it, I thought first gniess. As you talked about it, I thought yes has to be gniess. Then the next rock I thought it's granitic. (My favorite is granite.) But then I thought no, it's similar but not granite and doesn't seem right for granitodolimite either. OK, it's my first pegmatite. I'm trying now to try to identify before you tell us. Then, with the mica (I love the shinny), I was saying you have learned what has mica, but I couldn't remember. Schist is another rock I had heard of but had no clue when I started the id series. This is very good practice for me! Thanks for giving us time to think through identification before you tell the rock. I'm going not rush through these 4 videos. I drove through the Wasatch about 3 times. I thought them really beautiful and rugged. Spring is here enough for me to gather my collected rocks from the garden. I'll bring them in to try to identify.
Will you get over to the SW side of the island? It’s my favorite place on the island benches very visible and pronounced rock outcropping elephant rock a good northern start to the fun south of it
Yeah, Elephant Head is a great area and has similar rocks. I used to map and sample in that area as an undergraduate. The area in the video was a bit more accessible so I chose it.
@Shawn Willsey A number of years ago, a Mary Sweitser, an archiologist was interviewed on 60 Minutes for having discovered plyable tissue, blood cells, veins, etc. from a petrified Tyrannosaurus Rex and that of Triceratops. It turned out that she was disolving minerals from a sample, but returned far later than she anticipated to find what remained was the tissue I just mentioned. She said that those creatures were not from the Cretaceous, but from a lot more recent, the Early Drias, I think she said. dissolved in a light acid solution.. Did she get the Nobel Prize? No! She was shown the door, instead. It is my theory that these creatures may have been caught up in a massive tidal wave that disintegrated their bodies, but at the same time, forced the mineral- saturated water into the tissues, impregnating them into rock. Here are two sites where the following two researchers acquired samples claimed they had them x-rayed and even acquired DNA. Michael Tellinger is from South Africa and show irrefutably 'mud fossils' of reptilian creatures as well as human body parts littered about the land. The devastation must have been phenomenal.

The garnets in the pegmatite are quite large, and euhedral, too. Do you have any idea about their chemical composition? Oftentimes garnets in igneous rocks are stabilized by their manganese content. I’ve done analyses of garnets from quartz diorite in B.C. but they were almandine.
You're not supposed to because it's a state park. I've got a bunch of these rocks with garnets embedded from the Silver Island Mountains about 5 miles northeast of Wendover. It's BLM land, you can collect out there.
I've found two sources on the web that state that the oldest rocks on Antelope Island are 550-570 M years old, whereas rocks aged 1.8 B years are found across the lake in the Wasatch Mtns. Why such a large discrepancy?
Not sure. Most of the rocks on the island are Farmington Canyon Complex, the 1.8 billion year old basement rocks. Pretty easy to verify on the published geologic map.

Covering 1.3 billion years and the Cambrian rocks are the youngest. Love that!
Fabulous Landscape and Geology,.

Noticed Shawn that you got your MSc at NAU, probably my favorite source for bright young geology graduates...Congrats
Thanks. I really loved my time and experience there.
Thanks. I really loved it there.
PS thanks for giving the GPS location where you started.
This is great! Thank you!

I heard its risen 3 feet so far and there is still a lot of snow left in Wasatch.
Exciting part 1 finding nice examples of our classroom subjects. Great place !
Thanks!
Love the way you laid this series out!Thank you!
Nice! 4 parts. Now I have a plan this evening
😃
Good Stuff! I was last their before the mammoth had arrived
Thx Prof for another interesting geo adventure. 4 part series? Sweet!✌
Holy schyst, gneiss video, thank you!
Great video. Thanks

Opps I think I ment granito-dierite.

Takes a while to hike /bike compared to the east side but the views are great
Yeah, Elephant Head is a great area and has similar rocks. I used to map and sample in that area as an undergraduate. The area in the video was a bit more accessible so I chose it.
Professor, what are your thought regarding mud fossils?
I am not sure what you mean. Mud is silt and clay, a size of sediment. Fossils are evidence of life forms. “Mud fossil”?

Any of those garnets worth chipping out Shawn?😃

@@Skank_and_Gutterboy I was just joking as I figured if they were worth being chipped out, they'd all be dust now.
Yeah ditto on the state park statement. The garnets are so well fused to the other minerals in the pegmatite, they would be very difficult to extract.
@@MountainFisher
Yep, I kinda figured. I considered it, too, but there's just no way.
What lake? 🥺
*Let the Sunshine In...*
I'd better get out before the midges emerge. I will pack my net just in case.

Hmmm! nice gneisses.

"That's some really gneiss schist, man!"
Brilliant presentation, most other you tubers are telling me that the earth is only 6, 000years old and antelope island is a petrified giant 😁😁😁😁😁😁
The uphill fight against this is real.
