You lost me at Paleozoic
Mining...holy stupid...mining!!! There is no natural explanation!!! Despite we doesnt no who did or when...but be scientific honest for G sake!
I just realized that your students are very lucky to have such a dedicated individual. It doesn't take a rocket scientist or professor to understand that you love what you're doing.🔨
I had the exact same experience in community college!
Thanks. I feel blessed every day to do what I do and try to never take it for granted (or granite 😉)
There's a similar looking isolated white mountain (hill) called "Crystal Mountain" which actually is "crystal" (quartz) near Burgdorf, Idaho. Would love to see you do a field trip to that one, too.
There is a ski area in the Cascades in WA called Crystal Mountain. A bit East of Seattle. Wonder how "crystal" got in it's name? Wikipedia is no help. Nor is the ski area website. Looks like it started as a ski area back in about 1949, but the mountain may have had that name prior to that?
I believe there is a similar patch that is white sand in stark contrast to its surroundings
@@user-ff4jl5ic9n !me too
Crystal Mountain in Quartzsite Arizona 🤠
i second that! cool video!! i think i might be one of those little trees growing from the tuff (?) (😁) because it is almost like looking really good..
Thanks for the info! note: On very clear mornings, typically in late May and mid-July, as the rising sun breaks the horizon, as seen from the East, Crystal Peak glows a bright neon orange-pink.
I considered becoming a geologist back in the '80s, which seemed a perfect fit for me at the time. At least, until our class geology professor told the entire class to forget about making it a career choice because there were 10,000 unemployed geologists in Denver alone. I'm still very interested in geology, but I ended up in electro/mechanical engineering instead.
Haha, me too, except our professor told us the jobs were in oil exploration, and I wasn't too interested in that!
Yep, it was the same advice in 2005. I still miss being out in the field.
What they never tell you is, every field has a lot of unemployed people. Better to be an unemployed geologist than an unemployed truck driver!
All states that depended on the jobs provided by the domestic production of oil took a big hit in the mid 80s.
I started as a young geologist in Golden, CO in 1979. I never had trouble finding work after my first job. After about 6 years I was a consulting hydrogeologist. It was too much travel to stay married so I became a custom timber frame home builder and stayed near home more. No money in it tho. And maybe the relationship should have ended back then! Forty years ago!
I feel ridiculously blessed to have someone like you explain and explore the geology of my area! Utah is a gorgeous state, and full of geological wonders. Would love to see you take a look at the Timpanogos cave!
I've learned that caves are very tricky (for me) to film. I'll keep it in mind though.
caves are biological. I expect it is a blood vessel
LOL
@@stew6302some are literally vaginas (literal titan vaginas) all over the world!! Vagina Cave, Womb Cave, etc
Years ago I worked for a summer as an Interp Ranger at Great Basin NP and on those typical clear summer days, in the late afternoons from the lookout point on the way to the upper Lehman campground that mountain would be particularly conspicuous and I'd always wondered about it with the intention of going to inspect it though I never had the chance so thanks for that great geologic story. It answers a lot of questions as well a bringing back a lot of great memories...PS, the previous hike up to Wheeler Peak was likewise a treat, and it reminds me of all the other great features in that region. Cheers.
What an elegantly told story; I love how you piece things together for us and present it in a way that a lay-person can understand. Thank you!
Glad you enjoyed it!
@@shawnwillsey you said the deposit was a pyroclastic flow but did it have water in it like from a melted glacier when it was deposited? And why weren't those holes and Cavities made by streams that excavated away the softer material that was next to them
@@doomoo5365 No glaciers in this region. No water in the pyroclastic flow. If streams had created the holes, we would expect stream deposits.
Very interesting!!
Yes, old wives tales he certainly has an ability as the rest of academia to push and relay hiperbaly Look at the evidence at mudfossil university:)
I’m an amateur geologist! I passed by this this weekend. Family and I went to nearby Roosevelt Hot Spring. I thought that this mountain stood out a lot! Super fascinating and really interesting to learn about. :)
As soft as the rock is as demonstrated later in the video, I'm surprised that it is harder than the surrounding Paleozoic sandstones during its formation.
Maybe Something wrong with the timetable ;)
@@abrakadabra9406 my thought too. It's an observation conflicting with the very "interesting story" (imaginative fiction) put together by the UGS.
Between you and Nick Zentner, I feel like I'm ready to take my exam for my associates in geology. Really appreciate what you're doing.
Thanks a lot, I really like when you clearly and logically explain the mysteries of just what that is there that we were otherwise mostly ignoring-
My family goes camping out there. We love exploring the west desert. Fossil Mountain is incredible as well. When I first visited I was mesmerized by this mountain and throughly enjoyed exploiting it with my children. Now when we go back I tell them everything I learned from watching by this video. Thank you!
Very interesting! Love the deductive thought process. 👍🏼
Great series of illustrations explaining how Crystal Peak came to be. I'm glad a geologist is here to explain everthing since
there has been a lot going on for 33 million years. Tafoni looks like Swiss cheese type rock. Calcium carbonate and
ancient sand dunes mixed together. Chemical weathering for yes those 30 million plus years gave it that natural sponge
look. A very interesting place to visit professor!
33 million years?
ancient sand dunes? I thought he said ash.
@@davebashford3753 The volcano had ashfall in it from a phreatic explosion but most of the white stuff has small bits of crystals from a sand bed from a long gone
ancient seabed that existed here over 33 million years ago. It is a mix that makes up the calcrete you see and was preserved by the volcano's action .
@@NFS305 Erosion going on that long to get the sponge- like look of the calcrete.
same question. Sand? @@davebashford3753
So weird, and so cool. Never would have guessed that was a pyroclastic flow that is now actually higher than its' surroundings.
I always thought that those holes were caused by the escape of volcanic gasses upon deposition like mud pots or bubbles.
Great content. Very informative and well produced. Keep 'em coming...thanx
I still think they're gas bubbles. I would like to see a fresh break that showed the inside of the rock.
It's very rare for gas bubbles (vesicles) to be this large. Large vesicles tend to only be in very thick, stiff lava (silica rich, rhyolitic). Remember that a pyroclastic flow has moved some distance from the vent and so most gases escape upward into atmosphere as the flow travels.
@@tommajor6239 See comment here.
@@shawnwillseyI too thought it was gas bubbles, but your explanation was perfect. I hadn’t thought of the effects of time/distance on gas release. So it’s safe to assume that this mountain will continue develop and display new holes for years to come as it erodes, allowing water to dissolve the deeper calcium deposits (until eventually nothing remains)?
Not far from Reno, there is a small crystal mound, I would guess roughly 20-30' diameter. You have to take a dirt road several miles to find it. I was in Reno in the year 2000 and someone told me how to find it and I did. It was quite interesting. It was pure white. By now it might be virtually gone by people collecting rocks from there.
Thanks for video. If you haven't already some content on the recently described Indian Peak-Caliente Caldera Complex would interest me. I assume this tuff was part of the associated vulcanism.
Great job of explaining this area. I’m not a geologist; just curious about lots of things, so your explanation was easy for me to follow! Thank you!
I came across that place several years ago while roaming the backroads of the desert. Thank you for your in depth analysis!
Where do you find these amazing places. So so cool. But I must admit that I was occasionally distracted by the miniature green vegetation existing amongst this grandeur. Not your field of expertise I know and not to be included in your posts but they are part of an entire ecosystem taking advantage of the underlying ground. Don’t get me started about insects/bugs. I love insects in their natural habitat. Plus of course the larger fauna.
I really liked your digression recently on the Aspen trees with their “pistol grip” trunks which related to land movement.
Keep it coming young fella. We interested/curious people want your knowledge.
Thank You for sharing an up close view and history of places I wish I had time to visit. In the 80s & 90s I flew hang gliders with an aggressive group of pilots all over the western US. Mostly on X country flights and at very high altitudes. The views were spectacular, to say the least. Wish we would have taken some of the time to do more exploring when we were on the ground.
New word for the day: tafoni! Thanks, great work.
Yes, pronounced "Ta phone knee".
My 2nd word learned today.
(Fiamme is the other one. I've been binge watching his videos.)
Fascinating. I like your giving clues and wondering musings, as I am beginning to think more of other situations you've covered. It gets me trying to analyze what is seen in this video. Your section showing what's known helped. I was thinking that somehow water was involved. I was surprised by the calcite being an erosional factor. I'm very familiar with areas that have calcite deposition. This is giving me a new viewpoint on calcite. What an interesting place. Of course, I wonder where the pyroclastic flows came from. And if it had to do with the series of hot spots across the west. This expands my Utah knowledge. I really mostly know the area traveling from Colorado to Idaho through Utah. Thank you.
That is one neat area! Thanks, Shawn, for showing it to us.
Fascinating as always. Keep these coming!😊
Your video truly makes me wish that I had taken geology years ago when I was in college. It's so interesting
Hi Shawn, another wonderful explanation of my backyard I only live 40 miles from there and have spent the majority of my life in Utah's West desert or Miller counties West desert One thing that I can't believe you didn't talk about her go to was the painted potholes which are only a mile and a half roughly north of your location there they are waterfall erosion holes similar to what you see at Niagara falls anyway they're very interesting if you should get back out into that country go check those out they're very pretty there's about five of them there and they're six seven ft deep three or four feet across anyway thanks again You're doing a wonderful job.
Fascinating geology, thanks!
Very awesome and interesting. Thank you for sharing this. It is always amazing to learn something new!
Very informative. Growing up in the country instilled a love of geology in me. Now as I delve into researching natural ceramic materials for pottery, I get to study geology and petrology even deeper. Love it! Oh, by the way we could almost be cousins! Cheers!
Awesome research on this video. Thanks for the explanation and history of the mountain. I will put this location in my bucket list and check out the xenoliths as they have a story to tell as well. Thanks for a great video !!
I’m a rockhound so I actually study geography of the locations prior to my trips . I never thought I would be so interested in the topic and it’s amazing
Thanks for explaining that amazing landscape!
Nice video! Thank you. It’s really interesting to see a geologist at work, and also see a geologist using the work of other people over many years to try and understand the features of the landscape.
Glad you enjoyed it!
Fascinating and extremely well presented! Excellent content
Absolutely Fascinating!! I LOVE learning this stuff! Thank You, Shawn!!
Way cool! I've often wondered about those Swiss Cheese holes. Always figured it was water lapping at it, getting lower as the inland sea fell. But cool to hear the real dope on it. Thanks!
That was interesting. I learn something with every video.
Wow! There is so much fascinating information here! As you speak about the actions which created this geology, I can picture them occurring. What's more difficult to imagine is the length of time it actually took. Thank you, Professor. Glad I found (and subscribed to ) your channel. 🙂
Many thanks! Enjoy the existing geology videos.
Very interesting and great explanation. Thanks for sharing the info.
Dang it, I've got work to do, and you just had to post this video. Oh, well, guess I'm in...
Thank you Shawn. Learned a lot, including a new word "Tafoni". Will catch you on Nick's live stream.
Seen that tafoni weathering in quite a few places along the SoCal coastline, in sandstone. Great channel, keep it up.
Nice geologic tour. Thanks.
Love the story! Thanks for teaching this awesome geology.
Really unusual scene; beckons to be climbed. Again, the scope of geology is unimaginably huge. You do a great job explaining and showing us. ❤
Check out Upheaval Dome in Canyonlands....it looks like this but it's surrounded by a round cliff, almost like a crater.
Brilliant analysis
Another cool Utah desert geological mystery on my list has been solved. Thank you Shawn!
Epistemology of tafoni (pronounced taf-owe-ni, not taf-on-i). First appeared in a geological publication in Italy in 1882. May derive from the Greek taphos, meaning tomb, or from the Corsican word taffoni (two effs!) meaning window, or from tafonare (one eff!) meaning to perforate. Also, in Sicilian the word tafoni (one eff!) means window.
Thanks!
Very interesting! ... At first I guessed wind blown material, but then you mentioned no round rocks and I was puzzled... well done!! Thanks for posting this video!!
Very clear and detailed explanation for students of geology. 👍✌️
Great location and story! Thx!
So interesting. Thank you for this video.
very interesting.. thanks Shawn
Interesting stuff. Thanks for posting.
Amazing how the plants take root and grow in the tiniest bit of soil
Great geo-ed adventure. Thx Prof. ✌🏻
Thank you for this fascinating video. My father was a geologist who worked for many years at Kennecott (long before the Rio Tinto days). and he was passionate about the stories the earth tells and the mysteries it holds. Much like you, he was a great narrator of those tales. I'm picky about channels I subscribe to, but I'm adding yours today.
Awesome. Welcome aboard and enjoy the existing videos.
Nicely educational, always good to increase one understanding of geology…
I've always loved Science and History. My favorite subjects.
I'm a HUGE RockHound here in Oregon. Love learning about geology and geography which do go hand in hand. ❤❤❤❤❤
There so many cool places in the west desert. Great job!
Cool. Thanks for sharing.
I love science in all it’s forms. Geology is in my top three or four along with chemistry, meteorology, and my very favorite: astronomy. But I find this absolutely fascinating. Especially since I live in Salt Lake City, Utah. I’ve driven past Crystal Peak, but now I’m going to have to make it a definite stop on my list. Keep up the good work!
50 plus years ago I visited Drummond Island, MI, and I remember the rocky shore with smooth, round holes that were fascinating. Probably totally different, but thanks for the memory! And thanks so much for your clear communications about the seismic activity in Iceland.
Very absorbing ! I was intrigued by the calcite rich zenolith "crazy holes"
Very interesting. Thank you.
I thoroughly enjoyed your video. I felt like a member of your team on an expedition. Great job for that! I am happy that I was able to follow along and visualize these processes that formed this topography. I will definitely subscribe and enjoy watching more of this type of content. So glad you spell it the right way, too!!! (Your name 😆)
Happy Thanksgiving!
Welcome aboard! Enjoy the existing videos in the collection.
Wow enjoyed the learning. Nicely done
Thank you! Cheers!
New sub, thanks for the content. I found your video interesting informative and entertaining. I look forward to watching more from your channel.
Awesome. Welcome aboard. Enjoy the existing videos.
Wonderful story, well told.
*amazing*
(I should have gone into geology)
*super* interesting. TY for sharing!
Nice work!
Very interesting - TY 🙌🏼
Fascinating! Great fun.
Very enjoyable, Prof.
fascinating. thank you
Gracias. Me sirve mucho el proceso de razonamiento seguido. Las observaciones iniciales, tipo de roca, el ambiente circundante y las deducciones posteriores . En mi pais he visto tambien Tafonis en Ignimbritas ubicadas a 4000 msnm . Muy interesante. Saludos !
Excelente amigo! Muchas gracias.
Outstanding
Amazing place! THank you!
Thanks man, that was fun 🙂
All geologic stories are cool. Even if it is just years and years of sedimentation.
Fascinating!!!! Thank you!
Very good analysis and well presented ..........👍⛏️
Have you ever looked into a discussion about the Delaware Basin of Western Texas, Eastern New Mexico? Like your videos and your observations of the geology in the area discussed.
and thank you. very cool video!!!
this Tuff looks similar to the tuff/tufa at Cuma and Pompeii in Italy. Though that Cumaean tuff is more yellow. At first I thought the holes could caused by fallen trees or other organic matter that weathered away after being buried by pyroclastic flow in the same manner Pompeii was but now your calcite explanation makes sense. (Back in 2007-2009 I lived in the Campi Flegrei area near Cuma Tuff dome and was fascinated by that geology,. I hiked many of the craters there. I'm still bummed I didn't save the sulfur rock I had from Sulfotara).
Thanks! Awesome!!
Very interesting place. I will have to try to get there one of these days. The Italian word, tafoni, is pronounced tah-phone-ee. I think it means rock honeycomb, or some such. My Italian is not very good.
Great. That’s how I usually pronounce it too. Thanks.
That is cool! Thanks.
Awesome! So glad that I randomly ran across this channel. Utah has to be the most astounding state out of the 10-12 states that I've visited so far. Zion (my favorite National Park. I mean, it has Angels Landing AND The Narrows!!), The Grand Canyon (the most surreal "WTF" inducing place I've ever been), Lake Powell, Arches, Bryce Canyon....and those are only the places that I've been to.
You've then got Moab, Capital Reef, Canyonlands, Great Salt Lake, Bonneville Salt Flats, Grand Staircase, Goblin Valley, Dinosaur National Monument (hello fossils and ancient hieroglyphs!), Coral Pink Sand Dunes, the various slot canyons, etc. And I'm STILL leaving out a lot of other great destinations. It's absolutely insane. Anyone who simply thinks "Mormon desert" when they think Utah is doing themselves a severe disservice by not digging into the state a bit. It's an outdoorsman's paradise, as well as an astrologer's/recreational stargazer's, as it has a whopping 24 Dark Sky Reserves!! I can't wait until I visit again. I'm seeing the Great Sand Dunes of Colorado for the first time this weekend though :)
Keep up the awesome work Shawn! Geology rules!....or something like that
Geology rocks!
Great detective work.
I live in Utah Co., so cool to go see these Pt. of interest you have covered.
Wow! So interesting! Wish I had seen that, while living in Utah.
A great (modern) example of pyroclastic tephra and tuff filling and artificially flattening a valley is "the valley of ten thousand smokes" in Katmai, Alaska, where an eruption in the early 1900s scoured away all top soil and trees, and now the pyroclasts sit directly on top of jurassic age sedimentary rocks :) (which are nicely exposed thanks to a nearby river).
I has spotted this place on google earth when researching some of the trilobite locations nearby. I planned to check it out on the way home from a trip to the Grand Canyon, but a flat tire had me reconsider the miles of dirt roads required. Although you point out that it is quartzitic, I suppose I envisioned more of a solid quartzite, or perhaps actual quartz crystals in the area based on the name. Super interesting and I still hope to make it out there some day.
Not quartz. Tuffs.
Very knowledgeable geologist and interesting.
thanks
Thank you for the geology lesson. Much appreciated. Peace and love from the Olympic Peninsula in Washington State.🙏♥️🇺🇲
