A few viewers have commented that there are larger landslides that are under the ocean. That is absolutely true and I should have mentioned it. However, I think we should not compare them to each other as they are so different. Massive under water slides occur MUCH easier due to pore pressures. The Heart Mountain slide is truly the most astonishing and amazing in my opinion.
I was about to ask about Nuuanu. But sea landslides are alot easier to trigger and builds in a fashion that makes it build relatively fast. But to have a massive landslide like that on land is really wild. I wonder what kind of dustcloud that lifted up during that. I like how you said one of the options of the cause of this landslide was a large piece of land "gently" slid off of a low angle detachment. That's kinda scary. I would hate to see what a violent landslide detachment would entail. I'm curious how mixed up all the different layers really get. I bet it looked very confusing to early geologists.
It’s the lateral nature that blows my mind. Would you even realize it was a landslide if you were around at the time? You’d just think something is REALLY f***’d up! 😂
@@williambock1821 right if you were on top youde be surfing a huge chunk of earth. But I bet alot of liquefaction happens and everything gets mixed up.
You should do a video on the slumgullion slide earthflow. I find that totally fascinating too. To go there over 30 years ago then go back and find where we camped last time has moved a bit.
I'm a 13-year-old girl from Chicago, and I absolutely love your videos! I don't understand why most people in my generation have such little interest in the natural sciences. I love all of them, geology in particular. It makes me feel like something as every day as a rock has its own unique story behind it, and that story can be brought out through careful investigation and curiosity. You show such genuine passion in your videos, it's easy to impart some of that passion to the viewers of your channel, myself included! Rock on!
You sound like a very special girl, your right about geology!! Take as many Earth sciences classes as you can in school and then visit a few good geology schools. It may be something you want to do as a career? There are many many options open to you!
Keep up the good work, it turns out self-motivation is a crossover skill. In other words, whichever science or career path you focus on, your self-starting will bode you well. Do not think little (other than a humble demeanor is received well by many) of your gift. You will stay a step ahead, people asking for your time or view. Stay sharp, the world is your oyster. I'm 57 and find this man easy to agree with and fun to learn from. Geography ended up my love. Find yours
Myron, I want you to know some things. This quality of educational content is something I haven't run into before. Something that makes your work extra special is how genuinely excited you seem to share this with the world. Having grown up around foresters and geologists, I know that excitement exists, but it doesn't always come out publicly. Thank you for it, truly :). I was fortunate to work at the Illinois State Geological Survey while in undergrad, and spent a summer with a Devonian paleontologist who opened my eyes to the world of geology. It'd always been a side-hobby of mine, but never a focus. There are some days where I almost regret getting a GIS degree instead of one in Structural Geology, haha. Now I get to work as a cartographer and find your videos extremely inspirational. I'm lucky to live in a house with two other geographers who equally appreciate your channel. Just the other day we sat down and watched through this entire video in one sitting - a FRIDAY night spent digitally in the beautiful Bighorn basin. With my post-undergrad career starting up, I'm trying my best to start incorporating geology in my mapping work. I'll always be visiting your work to find inspiration and new locales to explore. All that being said - thank you for these videos and inspiring so many. Now living around the Denver metro area, a trip up north is perpetually enticing for me.
I have been a longtime viewer of www.youtube.com/@GeologyHub and just saw this channel mentioned on it's latest clip (also on the Heart Mountain slide) by a viewer. GeologyHub is mainly volcanoes, but has included a lot of other topics lately. He started off with gemstones 5 years ago and his vids are usually short, but informative. I'll definitely watch Myrons clip here when I have the time though, more in depth is good too :)
@@LostCylon Amazing proof of hydro-sorting, almost everywhere that you turned the camera, that would take extremely rapidly flowing and muddy water, going over the mountain tops !
My God!!! You're so strong, sir. I'm a geology student and I have a test tomorrow but I'm here watching your video. I am AMAZED by you. The way you teach is so so smooth and understandable, I could listen to you teach geology all day. Wish you good health, sir. 👍🏻🍀
Yes! I agree that your teaching skills are super!! You have made the video's I've watched SO extremely easy to understand. Thank you for taking all the time it takes to make these video's so EVERYONE can learn!
He's a born teacher. It's difficult to find the right balance between making it understandable to laymen and dumbing it down too far, so that it is still useful to knowledgeable people, but not over the head of those who merely are interested in it. And so that the latter become more the former with every video. He nails that balance perfectly.
I'm a retired plastic surgeon in Sydney, Australia. I started watching geology presented by Nick Zentner and now I'm watching you, Myron. You do a fantastic job. Thanks so much.
My Geology professor, Ed Chatelain at Valdosta State University, talked about Heart Mountain in his Structural Geology course, posing it as a question. How could this mountain have ended up so far from its base? Students: no clue. Lab Assistant (me): It slid‽! I’m so glad to hear the bigger story. Thanks Myron! And always, thanks, Ed.
When a good teacher or expert in their field is passionate about the subject being taught, they make it so interesting to those listening that they want to want to learn even more. You sir are a very good teacher. This is fascinating and that massive landslide was something I knew nothing about previous to watching your video. What a day that would have been. Thank you for making it.
i have been awed repeatedly throughout this video. what a colossal task you gave yourself! no wonder it took you multiple days . i love your enthusiasm for the geology and the past geologists. since i am older now and cannot walk, you have given me an opportunity to see the kind of nature i always loved to see. furthermore , my many years of interest in geology always got me to detour and travel when i was out west. THANK YOU
Myron, how wonderful it is to wander around Wyoming with you and NO ONE ELSE! Hikes like yours are almost impossible in our crowded islands - so called Great Britain but not that big at all - though with some interesting geological features because of plate tectonics and pure chance. As an adult I've sat on mountain tops that were laid down as sediment in long lost seas and while munching on a sandwich - ruminated on the fossil shellfish in the rocks and imagining the tape of history being replayed in my mind's eye. Many years ago ( I think I could probably give you a few!) I was thrashed for talking in class and not paying attention to teacher - I was further ridiculed because I thought the Americas were once joined to Africa. So incensed was I, that I cut up a school atlas and stuck all the pieces on a suitably sized ball. I left that ball on teacher's chair and treasure her face that stays with me today! I would love to dig her up and tell her about 20/30 mile blocks of rock that can move at 100mph. I also wrote to our Geology Museum - and they did write back - saying not to be so silly. The world needs more teachers like you.
For a fascinating view of Washington state and to a lesser extent, Oregon and California, look up Nick Zentner on TH-cam. Professor of Geology at Central Washington University. There are also live streams with about 800-1000 online at the same time.
Myron, I found your channel about a month ago and I'm hooked! I'm having a fun time working my way through your videos. Thank you so much for your time, effort and generosity of knowledge! Your enthusiasm for the geology really comes through. I am definitely putting some of these areas into my list of places to see and adventure in when I retire in a couple of years. Love the drone footage too, this is just really well done! Geology stories like this are so mind blowing, and humbling.
I would just like to have you with me every time I hike, to explain the geology. I love to see and speculate and read about how the geology came to be for an area. This video, and your others, open up whole new ways of thinking about it. Thank you so much for enriching an already rich source of learning and awe.
As an instructor of 30+ years, first of all...nice job! I moved to Wyoming 6 weeks ago. I'm still in the jaw-dropping awe, of mother nature phase. I clearly see the forces at work as I explore the areas and try to imagine just how it could have happened. last week I drove down to the Flaming Gorge area, some geological loop in the Sheep Creek section. You have given me a great amount of knowledge and insight. Most of all, look at the detail....but step back and look for the scale of the area.
I found your channel this morning and am now binge watching everything you have! You are truly an amazing source of knowledge; thank you for explaining everything so well. “Let me get my whiteboard” on the slope(and everywhere!) I love it! Much of my family lives in Fremont county and I visit at least twice a year, every time I am amazed by the geology of Wyoming. Thank you for expanding on my understanding of what I am seeing.
I’m a geologist and I learn so much watching your videos. I did my field camp in Wyoming and remember seeing and discussing Heart mountain. I spent the following summer after field camp at Grand Teton working as a park ranger and have been back out to Wyoming about a half dozen times since, backpacking in the Tetons, Wind River and Bighorn mountains. I’d really like to do some hiking to those places in this video. Also, I like how your videos are off the beaten path and talking about places that are not well known.
Wow this was one of the coolest science stories and videos I've ever seen. Really amazing Mr. Myron. I can only imagine the hard work that went into making the props, the filming, and the editing. Bushwhacking up a creek to a cliff face is the fun part though right? You are covering some absolutely fascinating stuff on this channel. Really looking forward to more. Thanks!
Your videos are incredible. I'm so happy I found this channel. Theres all sorts of space documentary series like this, but not many geology videos and I'm just as fascinated with earth science as I am with space stuff. This series rivals anything on TV. Thank You. If you ever need a young enthusiastic and athletic man to help you with your travels and filming I'll drop everything I'm doing and help you.
I was a student of Ed Beutner's at F&M many years ago. I'm sure your review of past literature turned up some of his later research on a non-catastrophic/episodic emplacement of the Heart Mtn. allocthon. Interestingly, when I went to field camp in 1979 at the YBRA camp in Red Lodge, we were introduced to Heart Mtn. as a catastrophic event, aided by slide planes pressurized by Absaroka volcanic gasses. That area is very special to me. Thx for the trip down memory lane.
WOW! This is by far the MOST astonishing YT channel over the geology and geography I've ever encounter yet! So interesting!!! It was always too hard for me even to watch 10 minutes videos! But here is you watch 40-80 minutes ones like in a finger snap! WOW! Very very very great job, Sir!!!
MANY THANKS for this video, Myron. Have always had a fascination for Geology but with little knowledge of the subject. Your videos are fantastic, and I find the stories of how geologists found out about how the geological processes happened as fascinating as the geology itself. This video probably the best one so far, and I didn't know anything about this whatsoever before watching.
I agree with you on this. Here in southern Idaho we have Shawn Willsey and in northern Idaho we have Nick Zentner. I spent a lot of my youth exploring Wyoming. I’m glad to have Myron clear up some of my questions of the Bighorn basin.
Thank you so much! You took an event of a magnitude that is difficult to comprehend and guided us through it with excellent narration, visual aids, and video. I had an uncle who was a college professor, who left me with a lifelong interest in geology. Your enthusiasm reminds me of him.
You make learning awesome! I love understanding many, many things and this was interesting enough that I rewound the video a few times to make sure I didn't miss anything!! I'm not formally educated but I still am fascinated by the natural processes that can be found everywhere. Thank you for a great video and all the hard work that went into it!!
You are so blessed to have this scenery and geology around you. Thank you very much for this video, I really like your way of explaining in fairly simple terms, but with out being condescending, I like how you took us on a journey with you explaning the processes from the resting point of Heart mountain and to it's origin.
Myron! What a fantastic and informative lesson. This is the second one I've watched in a row, the first one of yours only being about 29 minutes. I enjoyed the first one, and then I decided to watch this one too. Totally fascinating. As a National Park Ranger, natural history is fascinating to me, and while my specialty in the National Park Service is Structural Fire Prevention, I still love geology, geography, and history. Your videos are by far some of the most interesting and well composed on TH-cam! Thank you for taking the time to create these wonderful lessons! ~Blake Scott NPS.
I’m floored (no pun intended) You have hooked me Myron, beautifully described etched in visible evidence. I loved the artistry reference your kind passion was in keen focus! I’ve grown up the PNW area and felt Mt Saint Helens pop like someone chucking a basketball with great force against the side of my home over 300 miles away it was also noted for a landslide but nothing like the one you just described to me. Thank you for your time and your effort sharing your love of geology with us, it enriches my soul.
Absolutely love the content. You are the Bob Ross of geology. I felt alittle confused at first. But with you diagrams it all made perfect sense towards the end. I found especially fascinating the part about the heat being generated during the slide, essentially lubricating the plane.
I love the journey and the piecing together the puzzle to figure out what happened and how it happened. Kind of how they figured out that the west flank of the big island collapsed causing a tsunami thousands of feet high when they found corals on the top of another island. That was definitely on my mind in Hawaii.
Myron, I've now watched all of your videos. I hope you'll make more. It's so great to learn about the geology of the Big Horn Basin, a place I thought I knew until I watched these vids! The scene you describe 50mya is pretty intense... I think you're right that we're fortunate to NOT be living back then! Cheers
I just came across this video, I have watched two more of your videos and found them very interesting. I really like the way you explain geological features. You make it very easy to follow. I was wondering if the Absaroca volcanics were part of the Challis Magmatic Episode? Thank you for your time in bringing us these great videos!
I haven't enjoyed a virtual trek into the outlands so much! That the underpinnings of those mountains acted like teflon or water is mind blowing. Undersea slides have got nothing in common with what had to take place in Wyoming. And I missed it all when visiting the area fifty years ago - rats. This old disabled former rock hunter has found a new favorite buddy in Myron Cook. Thank you for sharing your time, energy, intellect, and ability to make occasionally tough ideas digestible for us amateurs and non-geologists. I'm gonna be a patron. Keep making videos as long as your knees hold out. God bless.
Thank you for making science interesting and easier to understand. Im planning a visit to Yellowstone next year so Im trying to take in lots of info about the area and its unique features. I cant wait to see some of surrounding features.
Sir, you are beyond a good teacher. You make learning fun. I have always loved geology but now I actually understand it (well,for a rock nerd anyway) Many blessings to you. For us too old to wander you provide a wonderful visual view along with the teaching.
Thank you for this Myron! One thing's for certain, I will never again drive Chief Joseph, Yellowstone to Cody, or the Beartooth, looking at them the same way as before. As you were setting up the detachment scenario I was thinking that there had to be something to lubricate that low angle surface, and then you explained it. It's like sliding on wet ice with almost zero slope. It's amazing to think that huge blocks from the Thunder Mountain area in Yellowstone ended up east of Cody. Fascinated as I am with geology from my youth, I was always left scratching my head a bit about this area as I drove through on my way up to the Pryors for wild horse photography. Your presentation helped a lot.
I absolutely love your videos. I'm a local pilot and always give some kind of geological lesson to my medical crew in the back as we fly around this beautiful state. I've always been curious about the Pumpkin Buttes, roughly 60 miles east of the Bighorns and just southwest of Savageton, WY. From what I understand these buttes originated from the peaks of the Sourthern Bighorns and are now 60 miles away. I'd be very interested in any video you might do on that area and the formation of the extensive coal bed in the area. Great videos, thanks!
I like very much your style, you are very good hiking and explaining at the same time! I don't know Wyoming but it looks like gorgeous. Twenty years ago I went through California, Nevada and Oregon up to Idaho and it was a wonderful geological and aesthetic experience: the history of the Earth is before you as a huge open book. Your enthusiasm is contagious.
Bravo, Sir! As a lifelong resident of Wyoming, this is something I was never aware of until stumbling upon your amazing video. I'm going to share this with my son and his family. I'm sure they'll be amazed, educated, and entertained as I was. Very well planned, filmed, and put together. That's not an easy task! Thank you!
I worked on two oil well drilling sites in 1982 and 1983. I lived near Helena , Montana at the time and referred to Wyoming as the "deep south". Saw Heart Mtn everyday. Wyoming landscape is stunning to me since I love the open spaces of our western states.
Thanks for sharing this amazing story! It boggles the mind to think of what it might have been like when the 20x30 mile area slid away at 200 mph or so! This earth we live on is a dynamic place!
I am so happy ,I came upon you, thank you for sharing your expertise in geology/ geography. I am a big map lover and love all of Earth's terrains all over the world. Excited to learn more about the beauty we have on earth and what I see. You give us the history and beginnings of that beautiful mountain .
23:06 Wow, I was just looking on a satellite map of that exact precipice as it had caught my eye as a place for a future visit to check out some geology. I had been scanning those red layers up the map from southern Utah when I had come across it. Probably on if the best folds in NA. Well what caught my eye was the vertical bedding planes at the north side of the Clark there, then the folds caught my eye subsequently. I did this all from the comfort of my west coast home. Thanks Myron for taking me there and letting me see it from ground level. How spectacular! Also, the rest of the video, so great, especially the whiteboard and the drone shots.
I saw huge blocks with slanted layers just like the ones in your video, when traveling west of Thermopolis (where our family lived), to the Yellowstone region. I often wondered how they were formed. Thanks to your video, I now understand. Also thanks for the addendum to your video, which was very helpful.
Kudos to you!!! Your wonderful style of presentation gives us the Real Hands/Feets-ON process of discovery!! Very well done--incredible geologic story & amazing how much of it is STILL VISIBLE to those of us Rock-Nerds persistent enough to get out there & find it!! Thank you so much for sharing with us, in such a successful way!!!
My wife and I have traveled through these areas several times on motorcycle trips. I have long marveled at the sedimentary stratification and thrust uplift of the mountains along Chief Joseph Hwy. You have answered so many questions, but also provided more than I could ever imagine. Thank you Sir. You have a new follower.
Thank you for your video of Wyoming history. Seeing all the different colors of dirt/rocks you can tell there was a lot of upheaval of the ground. Having traveled the route from Gillette to Casper many times (Dr. Appts.) you can see many interesting land formations along the way there also. Beautiful state Wyoming, so diverse.
Another cracking geological voyage with Captain Myron at the helm, absolutely fascinating stuff! Was just wondering, the scenery looks amazing as you're out and about in the field, I noticed you were carrying bear spray or something, are there wild animals you have to be wary of especially as you seem to go solo...would be interested to hear a short breakdown of what you have to take on a field trip and how you plan the route etc. Its obviously a very rugged isolated landscape with an element of danger involved...thanks for all your hard work with these videos, I can't stop looking at rock formations/layers when I'm in the hills!
Your videos are always so easy to understand and very interesting. The visuals are great and I always learn so much information from you. Awesome video Myron, hopefully your doing well and enjoying the beautiful landscape of Wyoming.
Just brilliant. Thank you. As someone who was born and lived the first twelve years of my life in PowellI I have been completely ignorant of any explanation for all the places near there that amazed my eyes and childish imagination. This is like coming full circle. Looking forward to more of your work!!
Love the video! I’m glad I know now, I always thought of heart mountain as the top of a volcano flying through the air and landing in its current spot. This information makes much more sense.
Setting aside all the amazing visuals of the geologic features discussed, as someone who has put together a few videos myself (nowhere near this level of quality), I'd like to take a moment to appreciate all the extra work it takes to set up and retrieve the camera to record yourself traversing. I've done it a few times, and it can easily add an hour to your trek. Excellent work, sir, that adds a layer of watchability to a video that you could have easily taken less time to complete. I also can't believe you haul that whiteboard up these mountains! Great job making this incredible phenomenon come to life!
Well, Myron. That was awesome. Thank you for all your work and time to share your knowledge. I am from Lander.(the Bear Guy) and i really love Geology. Thanks again!!!
Great video sir. I like geology very much but unfortunately ended up as an accountant. But your videos gives me back what I lost in my life. Thanks a lot Sir.👷♀️🙏🙏
I can't believe I've only just discovered your channel! Not only do you come across as a wonderful human being, you explain things in such a way that can easily grasped by someone with only a rudimentary grasp of geology. Thank you!
Outstanding video, stunning visuals, this is the first time I’m hearing of a mega slide in Wyoming, I had saw videos of 3 mega slides in Utah of similar size, and slid under the same conditions, they actually deposited a multi inch think layer of obsidian at the contact layer due to the melting of the volcanic material , I love these long form in depth explanations of geology
@@myroncook Amazing proof of hydro-sorting, almost everywhere that you turned the camera, that would take extremely turbulent and muddy water, going over the mountain tops !
Is there any chance that there could have been an inland ocean or large lake in the Bighorn basin at the time of this massive slide? I love your videos I grew up in Montana and remember the fascinating drive from Cook City to Cody via sunlight basin. Now having watched this video I hope to return and see it through the eyes of a geologist. Thank you Myron ✌🏾💪🏽🙏🏾
I love all your videos, I wish I had more of them to consume. I love how you engage the viewer with questions, your drawings that help explain it deeper to your calm yet happy and excited way of speaking. You are doing a amazing job explaining, and the fact that you are personally visiting the areas you are talking about, taking days, walking, filming is absolutely astounding. And the drone views are jawdropping. Truly a beautiful technology. I wish more people stumble upon your content. You deserve every view you get.
This is amazing. A wealth of information. I absolutely love everything about this video! Thank you for all the effort you put into this presentation. Best part, you don't take a whole 5 minutes talking about your sponsor or your Patreon supporters, or "hit like, subscribe and that bell". That kind of thing is a cancer on the Internet, so seeing a knowledge rich video like this with none of that BS is such a breath of fresh air.
Thank you again Mr Cook for all your hard work. Its obvious you've spent many many days, miles and muscles (the summit hike) to present all this extraordinary information. Keep up the good work!!
Having recently moved to South Africa where there is such interesting geology, I would love to have someone with your clarity to make it come to life. Your videos are excellent as you patiently build the picture and hold our interest.
The same hot spot under Yellowstone was under SW Washington, NE Oregon, and Western Idaho. Millions of years ago, fissures appeared and released Flood Basalt that traveled all the way to Columbia River. It buried parts of Washington, Oregon, and Idaho. I live in Central Washington. Numerous layers of Flood Basalt are over 1 mile thick. In some places it is over 2 miles thick. The Yakima River Canyon is great place to see many layers in plain view.
The deepest part of the Columbia river basalt formation is at Prosser. Its 3 miles thick at that geographic point. Shell, EXXON-MOBIL, and BP, performed exploratory drilling in several spots throughout eastern Washington. There is a sizable crude oil deposit under eastern Washington. I certainly hope that you have viewed Nick Zentners documentary on the Columbia river basalt formation. Thank you for mentioning this.
@@TheErik249 Thanks, I live in Yakima and they drilled here too. Not sure how thick, but based on gaps carved by Yakima River in the ridges, see lots of Basalt. We only see the top several thousand feet.
Besides the Heart Mountain landslide, I recommend reading up on the recently-discovered Markagunt and Sevier gravity slides in Utah…they about the same size as Heart Mountain (~2000 sq mi displaced terrain). The Markagunt and Sevier gravity slides are thought to be related to inflation of calderas in the region during the Mid-Tertiary ignimbrite flare-up. Really interesting structural geology and fascinating pseudotachylites. This is a great video-your work is really appreciated! Question: does the detachment actually make a sharp angle (as drawn in the video) between it and the heardscarp of the slide, or is it actually more of a listric, curved scarp?
Thank you for your feedback! I have read a paper and saw a youtube video on those giant Utah slides...impressive. The breakaway fault for the Heart Mtn slide does have the sharp angle. I'm not aware of anyone describing it as listric.
@@myroncook Thank you for confirming that detail on the geometry of the breakaway fault. Regarding the Utah gravity slides-IMO, one lesson to be learned there is just how long the geology was passed over as just “weird rocks” or “volcanics”. Given the sheer size of these kinds of events, field identification can be difficult. Now that there is more consciousness of these kinds of enormous gravity slides in the literature, I expect we might find that such events are more common in regions with a history of silicic caldera volcanism/ignimbrite flare-ups, than previously appreciated. For example: I expect such gravity slides might also come to be found in the Bolivian Altiplano, associated with its Pliocene ignimbrite flare-up, in the Sierra Madre Occidental of Mexico, and perhaps even in older ignimbrite complexes/silicic large igneous provinces such as Chon Aike in Patagonia. It seems that the combination of rapid accumulation of thick volcanic sequences with the kind of regional uplift and oversteepening and destabilization associated with caldera resurgence could be a recipe for this sort of disaster.
This was fabulous. I appreciate your making this video as clear as possible about things we can only imagine as we look at the evidence left behind. Blows my mind. Thank you.
Thank you for a very interesting presentation.Just ‘discovered’ your channel today and was very interested to learn about the geology in Wyoming. And see some of the places I have visited.
Mr. Cook, Thank you so much for sharing your knowledge and enthusiasm with me. It is a wonderful presentation. I'm glad to know there is a teachers like you, and proud to say I attended your class today... Thanks, again
Thank you so much for showing all of this Beautiful landscape. I absolutely love following you on all your hikes as it's something I've never been able to do. As always you've given so much information Just made my day.
What a delightful presentation. A few years ago, I stumbled upon the original paper presenting the CO2 pillow concept and was amazed at the speed, distance, and 2° angle. You have a gift in the way you present the delight of the discovery and the beauty of the earth. Thank you for using your time to give to others.
What an incredible time we live in that we can watch something so informative and interesting for free on the internet. Thank you so much for teaching us this!
I saw few videos from you, I absolutely love it, listen to your interesting education.I am 72 year grandma from Austria, living now in the USA, love this beautiful nature and the geological history about it, thank you!
A few viewers have commented that there are larger landslides that are under the ocean. That is absolutely true and I should have mentioned it. However, I think we should not compare them to each other as they are so different. Massive under water slides occur MUCH easier due to pore pressures. The Heart Mountain slide is truly the most astonishing and amazing in my opinion.
I agree Myron. My mind is still blown. Can't imagine watching mountains travel >150 mph🤯
I was about to ask about Nuuanu. But sea landslides are alot easier to trigger and builds in a fashion that makes it build relatively fast. But to have a massive landslide like that on land is really wild. I wonder what kind of dustcloud that lifted up during that. I like how you said one of the options of the cause of this landslide was a large piece of land "gently" slid off of a low angle detachment. That's kinda scary. I would hate to see what a violent landslide detachment would entail. I'm curious how mixed up all the different layers really get. I bet it looked very confusing to early geologists.
It’s the lateral nature that blows my mind. Would you even realize it was a landslide if you were around at the time? You’d just think something is REALLY f***’d up! 😂
@@williambock1821 right if you were on top youde be surfing a huge chunk of earth. But I bet alot of liquefaction happens and everything gets mixed up.
You should do a video on the slumgullion slide earthflow. I find that totally fascinating too. To go there over 30 years ago then go back and find where we camped last time has moved a bit.
The production value of this video is OFF THE CHARTS. Incredible filmmaking.
Thanks!
I'm a 13-year-old girl from Chicago, and I absolutely love your videos! I don't understand why most people in my generation have such little interest in the natural sciences. I love all of them, geology in particular. It makes me feel like something as every day as a rock has its own unique story behind it, and that story can be brought out through careful investigation and curiosity. You show such genuine passion in your videos, it's easy to impart some of that passion to the viewers of your channel, myself included! Rock on!
You made my day! March on with your curious mind.
Well done @verysquarebear . Learning is a gift that will keep giving as you grow older.
You sound like a very special girl, your right about geology!! Take as many Earth sciences classes as you can in school and then visit a few good geology schools. It may be something you want to do as a career? There are many many options open to you!
Keep up the good work, it turns out self-motivation is a crossover skill. In other words, whichever science or career path you focus on, your self-starting will bode you well. Do not think little (other than a humble demeanor is received well by many) of your gift. You will stay a step ahead, people asking for your time or view. Stay sharp, the world is your oyster. I'm 57 and find this man easy to agree with and fun to learn from. Geography ended up my love. Find yours
@@liamgross7217ty so much, I tried to say as much with only 7 or 8 paragraphs lol
Myron, I want you to know some things.
This quality of educational content is something I haven't run into before. Something that makes your work extra special is how genuinely excited you seem to share this with the world. Having grown up around foresters and geologists, I know that excitement exists, but it doesn't always come out publicly. Thank you for it, truly :).
I was fortunate to work at the Illinois State Geological Survey while in undergrad, and spent a summer with a Devonian paleontologist who opened my eyes to the world of geology. It'd always been a side-hobby of mine, but never a focus. There are some days where I almost regret getting a GIS degree instead of one in Structural Geology, haha. Now I get to work as a cartographer and find your videos extremely inspirational.
I'm lucky to live in a house with two other geographers who equally appreciate your channel. Just the other day we sat down and watched through this entire video in one sitting - a FRIDAY night spent digitally in the beautiful Bighorn basin. With my post-undergrad career starting up, I'm trying my best to start incorporating geology in my mapping work. I'll always be visiting your work to find inspiration and new locales to explore.
All that being said - thank you for these videos and inspiring so many. Now living around the Denver metro area, a trip up north is perpetually enticing for me.
You made my day, Jakob!!! Keep being inspired and life will continue to amaze.
Good luck in your post grad endeavors! I see you are a trailblazer. Cartography is freaking awesome too, especially historically! Good men🙌
I have been a longtime viewer of www.youtube.com/@GeologyHub and just saw this channel mentioned on it's latest clip (also on the Heart Mountain slide) by a viewer. GeologyHub is mainly volcanoes, but has included a lot of other topics lately. He started off with gemstones 5 years ago and his vids are usually short, but informative. I'll definitely watch Myrons clip here when I have the time though, more in depth is good too :)
@@LostCylon Amazing proof of hydro-sorting, almost everywhere that you turned the camera, that would take extremely rapidly flowing and muddy water, going over the mountain tops !
What does your work as a cartographer or geographer entail? Sounds like a great job that I would love
My God!!! You're so strong, sir. I'm a geology student and I have a test tomorrow but I'm here watching your video. I am AMAZED by you. The way you teach is so so smooth and understandable, I could listen to you teach geology all day. Wish you good health, sir. 👍🏻🍀
Yes! I agree that your teaching skills are super!! You have made the video's I've watched SO extremely easy to understand. Thank you for taking all the time it takes to make these video's so EVERYONE can learn!
He is a modest professional of the very highest standards!
He's a born teacher. It's difficult to find the right balance between making it understandable to laymen and dumbing it down too far, so that it is still useful to knowledgeable people, but not over the head of those who merely are interested in it. And so that the latter become more the former with every video.
He nails that balance perfectly.
I'm a retired plastic surgeon in Sydney, Australia. I started watching geology presented by Nick Zentner and now I'm watching you, Myron. You do a fantastic job. Thanks so much.
thanks!
My Geology professor, Ed Chatelain at Valdosta State University, talked about Heart Mountain in his Structural Geology course, posing it as a question. How could this mountain have ended up so far from its base? Students: no clue. Lab Assistant (me): It slid‽!
I’m so glad to hear the bigger story. Thanks Myron! And always, thanks, Ed.
When a good teacher or expert in their field is passionate about the subject being taught, they make it so interesting to those listening that they want to want to learn even more.
You sir are a very good teacher.
This is fascinating and that massive landslide was something I knew nothing about previous to watching your video. What a day that would have been.
Thank you for making it.
Thank you!
Fascinating talk!
i have been awed repeatedly throughout this video. what a colossal task you gave yourself! no wonder it took you multiple days . i love your enthusiasm for the geology and the past geologists. since i am older now and cannot walk, you have given me an opportunity to see the kind of nature i always loved to see. furthermore , my many years of interest in geology always got me to detour and travel when i was out west. THANK YOU
Thank you so much, Kathleen. You made my day with this feedback!
Myron, how wonderful it is to wander around Wyoming with you and NO ONE ELSE! Hikes like yours are almost impossible in our crowded islands - so called Great Britain but not that big at all - though with some interesting geological features because of plate tectonics and pure chance.
As an adult I've sat on mountain tops that were laid down as sediment in long lost seas and while munching on a sandwich - ruminated on the fossil shellfish in the rocks and imagining the tape of history being replayed in my mind's eye.
Many years ago ( I think I could probably give you a few!) I was thrashed for talking in class and not paying attention to teacher - I was further ridiculed because I thought the Americas were once joined to Africa. So incensed was I, that I cut up a school atlas and stuck all the pieces on a suitably sized ball. I left that ball on teacher's chair and treasure her face that stays with me today! I would love to dig her up and tell her about 20/30 mile blocks of rock that can move at 100mph.
I also wrote to our Geology Museum - and they did write back - saying not to be so silly.
The world needs more teachers like you.
Great story!
I love how geologists read a landscape, and through careful work can map how it happened. Good stuff
I wish every state had a guy like you! I bet it'd make a lot of people take road trips and find a new appreciation for their home.
For a fascinating view of Washington state and to a lesser extent, Oregon and California, look up Nick Zentner on TH-cam. Professor of Geology at Central Washington University. There are also live streams with about 800-1000 online at the same time.

Myron, I found your channel about a month ago and I'm hooked! I'm having a fun time working my way through your videos. Thank you so much for your time, effort and generosity of knowledge! Your enthusiasm for the geology really comes through. I am definitely putting some of these areas into my list of places to see and adventure in when I retire in a couple of years. Love the drone footage too, this is just really well done! Geology stories like this are so mind blowing, and humbling.
Thank you for your feedback, Mike. Makes my day!
I would just like to have you with me every time I hike, to explain the geology. I love to see and speculate and read about how the geology came to be for an area. This video, and your others, open up whole new ways of thinking about it. Thank you so much for enriching an already rich source of learning and awe.
As an instructor of 30+ years, first of all...nice job! I moved to Wyoming 6 weeks ago. I'm still in the jaw-dropping awe, of mother nature phase. I clearly see the forces at work as I explore the areas and try to imagine just how it could have happened. last week I drove down to the Flaming Gorge area, some geological loop in the Sheep Creek section. You have given me a great amount of knowledge and insight. Most of all, look at the detail....but step back and look for the scale of the area.
Thank you for the feedback. Especially from an instructor!
I found your channel this morning and am now binge watching everything you have!
You are truly an amazing source of knowledge; thank you for explaining everything so well.
“Let me get my whiteboard” on the slope(and everywhere!) I love it!
Much of my family lives in Fremont county and I visit at least twice a year, every time I am amazed by the geology of Wyoming. Thank you for expanding on my understanding of what I am seeing.
Thanks and welcome
I’m a geologist and I learn so much watching your videos. I did my field camp in Wyoming and remember seeing and discussing Heart mountain. I spent the following summer after field camp at Grand Teton working as a park ranger and have been back out to Wyoming about a half dozen times since, backpacking in the Tetons, Wind River and Bighorn mountains.
I’d really like to do some hiking to those places in this video. Also, I like how your videos are off the beaten path and talking about places that are not well known.
Thank you for the feedback! Careful hiking in the Absarokas...bears are thick.
Wow this was one of the coolest science stories and videos I've ever seen. Really amazing Mr. Myron. I can only imagine the hard work that went into making the props, the filming, and the editing. Bushwhacking up a creek to a cliff face is the fun part though right? You are covering some absolutely fascinating stuff on this channel. Really looking forward to more. Thanks!
Thank you, Shane! This feedback made my day...I'm a bit humbled by the outpouring of interest.
Nicely Done! Your video reminded me of Crater Lake. It would be interesting to see a comparison to these events. Thanks for sharing your knowledge.
Your videos are incredible. I'm so happy I found this channel. Theres all sorts of space documentary series like this, but not many geology videos and I'm just as fascinated with earth science as I am with space stuff. This series rivals anything on TV. Thank You. If you ever need a young enthusiastic and athletic man to help you with your travels and filming I'll drop everything I'm doing and help you.
Thank you, Nicholas! I may take you up on that sometime!
I was a student of Ed Beutner's at F&M many years ago. I'm sure your review of past literature turned up some of his later research on a non-catastrophic/episodic emplacement of the Heart Mtn. allocthon. Interestingly, when I went to field camp in 1979 at the YBRA camp in Red Lodge, we were introduced to Heart Mtn. as a catastrophic event, aided by slide planes pressurized by Absaroka volcanic gasses. That area is very special to me. Thx for the trip down memory lane.
Beutner slide block, lemhi range. Part of my education.
WOW! This is by far the MOST astonishing YT channel over the geology and geography I've ever encounter yet! So interesting!!! It was always too hard for me even to watch 10 minutes videos! But here is you watch 40-80 minutes ones like in a finger snap! WOW! Very very very great job, Sir!!!
Wow, thank you!
I get a better education on YT than i ever did in college. Thanks, Mr. Cook!
MANY THANKS for this video, Myron. Have always had a fascination for Geology but with little knowledge of the subject. Your videos are fantastic, and I find the stories of how geologists found out about how the geological processes happened as fascinating as the geology itself. This video probably the best one so far, and I didn't know anything about this whatsoever before watching.
Glad you enjoyed it
This was amazing, thank you Mr. Cook for all your work on this. It was pretty obvious that this was a labor of love for geology for you.
Glad you enjoyed it!
I agree with you on this. Here in southern Idaho we have Shawn Willsey and in northern Idaho we have Nick Zentner. I spent a lot of my youth exploring Wyoming. I’m glad to have Myron clear up some of my questions of the Bighorn basin.
Really appreciate the time and effort you have put in to this. Really enjoyed it!
Glad you enjoyed it!
Thank you so much! You took an event of a magnitude that is difficult to comprehend and guided us through it with excellent narration, visual aids, and video. I had an uncle who was a college professor, who left me with a lifelong interest in geology. Your enthusiasm reminds me of him.
Thank you... what a compliment
You make learning awesome! I love understanding many, many things and this was interesting enough that I rewound the video a few times to make sure I didn't miss anything!! I'm not formally educated but I still am fascinated by the natural processes that can be found everywhere. Thank you for a great video and all the hard work that went into it!!
Awesome, thank you!
You are so blessed to have this scenery and geology around you.
Thank you very much for this video, I really like your way of explaining in fairly simple terms, but with out being condescending, I like how you took us on a journey with you explaning the processes from the resting point of Heart mountain and to it's origin.
I feel extremely fortunate to have grown up around this amazing geology. Thank you for the feedback!
Myron! What a fantastic and informative lesson. This is the second one I've watched in a row, the first one of yours only being about 29 minutes. I enjoyed the first one, and then I decided to watch this one too. Totally fascinating. As a National Park Ranger, natural history is fascinating to me, and while my specialty in the National Park Service is Structural Fire Prevention, I still love geology, geography, and history. Your videos are by far some of the most interesting and well composed on TH-cam! Thank you for taking the time to create these wonderful lessons! ~Blake Scott NPS.
Thank you for your feedback, Blake. Comments like this keep me motivated to continue. All the best
😍😍😍😍😍what STUNNING land!!!! Ty for taking us along! The landscape is telling us a historical storyline that we normally do not pay attention to!
I’m floored (no pun intended)
You have hooked me Myron, beautifully described etched in visible evidence.
I loved the artistry reference your kind passion was in keen focus!
I’ve grown up the PNW area and felt Mt Saint Helens pop like someone chucking a basketball with great force against the side of my home over 300 miles away it was also noted for a landslide but nothing like the one you just described to me.
Thank you for your time and your effort sharing your love of geology with us, it enriches my soul.
Thank you for appreciating the artistic side. It is very important to me.
Absolutely love the content. You are the Bob Ross of geology. I felt alittle confused at first. But with you diagrams it all made perfect sense towards the end. I found especially fascinating the part about the heat being generated during the slide, essentially lubricating the plane.
Awesome, thank you!
I love the journey and the piecing together the puzzle to figure out what happened and how it happened. Kind of how they figured out that the west flank of the big island collapsed causing a tsunami thousands of feet high when they found corals on the top of another island. That was definitely on my mind in Hawaii.
An amazing story, scarcely believable to us living in peaceful geological times, but told clearly amidst grand scenery - fascinating.
Myron, I've now watched all of your videos. I hope you'll make more. It's so great to learn about the geology of the Big Horn Basin, a place I thought I knew until I watched these vids! The scene you describe 50mya is pretty intense... I think you're right that we're fortunate to NOT be living back then! Cheers
Fascinating story. Your diagrams and drone footage really illustrate how it all came about. Thank you.
I just came across this video, I have watched two more of your videos and found them very interesting. I really like the way you explain geological features. You make it very easy to follow. I was wondering if the Absaroca volcanics were part of the Challis Magmatic Episode? Thank you for your time in bringing us these great videos!
I'm glad you enjoyed it! I'm not sure about the Challis system, but it wouldn't surprise me if they are related.
Great presentation. What a beautiful place! Thank you for sharing.
I haven't enjoyed a virtual trek into the outlands so much! That the underpinnings of those mountains acted like teflon or water is mind blowing. Undersea slides have got nothing in common with what had to take place in Wyoming. And I missed it all when visiting the area fifty years ago - rats. This old disabled former rock hunter has found a new favorite buddy in Myron Cook. Thank you for sharing your time, energy, intellect, and ability to make occasionally tough ideas digestible for us amateurs and non-geologists. I'm gonna be a patron. Keep making videos as long as your knees hold out. God bless.
Thank you, Crazi!
Thank you for making science interesting and easier to understand. Im planning a visit to Yellowstone next year so Im trying to take in lots of info about the area and its unique features. I cant wait to see some of surrounding features.
Have fun!
Sir, you are beyond a good teacher. You make learning fun. I have always loved geology but now I actually understand it (well,for a rock nerd anyway) Many blessings to you. For us too old to wander you provide a wonderful visual view along with the teaching.
What an amazing gift you have given the world by taking time to share your expertise and knowledge of these fascinating geographic areas.
Thank you for this Myron! One thing's for certain, I will never again drive Chief Joseph, Yellowstone to Cody, or the Beartooth, looking at them the same way as before. As you were setting up the detachment scenario I was thinking that there had to be something to lubricate that low angle surface, and then you explained it. It's like sliding on wet ice with almost zero slope.
It's amazing to think that huge blocks from the Thunder Mountain area in Yellowstone ended up east of Cody. Fascinated as I am with geology from my youth, I was always left scratching my head a bit about this area as I drove through on my way up to the Pryors for wild horse photography. Your presentation helped a lot.
I'm glad you enjoyed it, Steve.
I absolutely love your videos. I'm a local pilot and always give some kind of geological lesson to my medical crew in the back as we fly around this beautiful state. I've always been curious about the Pumpkin Buttes, roughly 60 miles east of the Bighorns and just southwest of Savageton, WY. From what I understand these buttes originated from the peaks of the Sourthern Bighorns and are now 60 miles away. I'd be very interested in any video you might do on that area and the formation of the extensive coal bed in the area. Great videos, thanks!
Pumpkin buttes are interesting; I will be using them in a future video. They are a remnant of a high peneplain.
I like very much your style, you are very good hiking and explaining at the same time! I don't know Wyoming but it looks like gorgeous. Twenty years ago I went through California, Nevada and Oregon up to Idaho and it was a wonderful geological and aesthetic experience: the history of the Earth is before you as a huge open book. Your enthusiasm is contagious.
Thank you very much!
Bravo, Sir!
As a lifelong resident of Wyoming, this is something I was never aware of until stumbling upon your amazing video.
I'm going to share this with my son and his family. I'm sure they'll be amazed, educated, and entertained as I was.
Very well planned, filmed, and put together. That's not an easy task!
Thank you!
Thank you very much!
I worked on two oil well drilling sites in 1982 and 1983. I lived near Helena , Montana at the time and referred to Wyoming as the "deep south". Saw Heart Mtn everyday. Wyoming landscape is stunning to me since I love the open spaces of our western states.
The sizes heights and distances just blow my mind. Thank you for a survey of a most fascinating and astonishing geological marvel.
Thanks for sharing this amazing story! It boggles the mind to think of what it might have been like when the 20x30 mile area slid away at 200 mph or so! This earth we live on is a dynamic place!
My thoughts exactly
Yes,Earth.is.a.dynamic.place.and.is.in.a.state.of.constant.change!!!Too.bad.so.many.people.panic.when.they.discover.the.climate.part.of.Earth.also.changes...They.can't.seem.to.understand.our.dynamic.climate.has.been.changing.every.day.since.Earth.developed.an.atmosphere.BILLIONS.of.years.ago.
Amazing and beautiful education / Thank you Myron
You are very welcome
Keep going Sir...., this is what type of geological video that I want and always looking for
Thank you for the feedback.
I'm a 58 old from SW Louisiana & enjoy your videos. Actually, as the young lady prior my post said, "absolutely".
Thank you for teaching me you are a good teacher.
Thank you
You are a great geological storyteller, that brings us back to hear you time and again!
I am so happy ,I came upon you, thank you for sharing your expertise in geology/ geography. I am a big map lover and love all of Earth's terrains all over the world. Excited to learn more about the beauty we have on earth and what I see. You give us the history and beginnings of that beautiful mountain .
Thanks and welcome

Wow, I was just looking on a satellite map of that exact precipice as it had caught my eye as a place for a future visit to check out some geology. I had been scanning those red layers up the map from southern Utah when I had come across it. Probably on if the best folds in NA. Well what caught my eye was the vertical bedding planes at the north side of the Clark there, then the folds caught my eye subsequently. I did this all from the comfort of my west coast home. Thanks Myron for taking me there and letting me see it from ground level. How spectacular!
Also, the rest of the video, so great, especially the whiteboard and the drone shots.
I saw huge blocks with slanted layers just like the ones in your video, when traveling west of Thermopolis (where our family lived), to the Yellowstone region. I often wondered how they were formed. Thanks to your video, I now understand. Also thanks for the addendum to your video, which was very helpful.
Thank-you very much for sharing such amazing knowledge, great presentation of a fantastic event !
Kudos to you!!! Your wonderful style of presentation gives us the Real Hands/Feets-ON process of discovery!! Very well done--incredible geologic story & amazing how much of it is STILL VISIBLE to those of us Rock-Nerds persistent enough to get out there & find it!! Thank you so much for sharing with us, in such a successful way!!!
Thank you very much!
My wife and I have traveled through these areas several times on motorcycle trips. I have long marveled at the sedimentary stratification and thrust uplift of the mountains along Chief Joseph Hwy.
You have answered so many questions, but also provided more than I could ever imagine.
Thank you Sir. You have a new follower.
That is awesome!
Thank you for your video of Wyoming history. Seeing all the different colors of dirt/rocks you can tell there was a lot of upheaval of the ground. Having traveled the route from Gillette to Casper many times (Dr. Appts.) you can see many interesting land formations along the way there also. Beautiful state Wyoming, so diverse.
Glad you enjoyed it!
Just found your channel, and I love it. Beautiful scenery and well studied knowledge.
Really nice video! You gotta love technology, a lot easier to see and explain.
Couldn't agree more!
Another cracking geological voyage with Captain Myron at the helm, absolutely fascinating stuff! Was just wondering, the scenery looks amazing as you're out and about in the field, I noticed you were carrying bear spray or something, are there wild animals you have to be wary of especially as you seem to go solo...would be interested to hear a short breakdown of what you have to take on a field trip and how you plan the route etc. Its obviously a very rugged isolated landscape with an element of danger involved...thanks for all your hard work with these videos, I can't stop looking at rock formations/layers when I'm in the hills!
Amazing and fantastic video! Thanks for very well explained and easily understandable contents.
Glad you enjoyed it!
Your videos are always so easy to understand and very interesting. The visuals are great and I always learn so much information from you. Awesome video Myron, hopefully your doing well and enjoying the beautiful landscape of Wyoming.
Just brilliant. Thank you. As someone who was born and lived the first twelve years of my life in PowellI I have been completely ignorant of any explanation for all the places near there that amazed my eyes and childish imagination. This is like coming full circle. Looking forward to more of your work!!
Thank you for the feedback!
Hi, I just watched a vid of yours then came here.. I like what you do... Thanks for sharing, this topic has always interested me.
Love the video! I’m glad I know now, I always thought of heart mountain as the top of a volcano flying through the air and landing in its current spot. This information makes much more sense.
It is an amazing story.
Setting aside all the amazing visuals of the geologic features discussed, as someone who has put together a few videos myself (nowhere near this level of quality), I'd like to take a moment to appreciate all the extra work it takes to set up and retrieve the camera to record yourself traversing. I've done it a few times, and it can easily add an hour to your trek. Excellent work, sir, that adds a layer of watchability to a video that you could have easily taken less time to complete. I also can't believe you haul that whiteboard up these mountains! Great job making this incredible phenomenon come to life!
thanks!
Well, Myron. That was awesome. Thank you for all your work and time to share your knowledge. I am from Lander.(the Bear Guy) and i really love Geology. Thanks again!!!
I am glad you enjoyed it!
One of the best videos on all of TH-cam, and I mean that!
thank you!
I really enjoyed this presentation and learned a whole lot! You are a good teacher.
Glad you enjoyed it!
Great video sir. I like geology very much but unfortunately ended up as an accountant. But your videos gives me back what I lost in my life. Thanks a lot Sir.👷♀️🙏🙏
Thank you so much for your feedback
I can't believe I've only just discovered your channel! Not only do you come across as a wonderful human being, you explain things in such a way that can easily grasped by someone with only a rudimentary grasp of geology. Thank you!
Outstanding video, stunning visuals, this is the first time I’m hearing of a mega slide in Wyoming, I had saw videos of 3 mega slides in Utah of similar size, and slid under the same conditions, they actually deposited a multi inch think layer of obsidian at the contact layer due to the melting of the volcanic material , I love these long form in depth explanations of geology
I'm glad you liked the video. Tune in...I'll be releasing more.
Bobby it always startles me seeing a name like yours. I had a brother killed in Vietnam in 69. His name was also Bobby Adkins.
@@georgeadkins7587 adkins is a very common name where I’m from, many of them are vets too.
@@myroncook Amazing proof of hydro-sorting, almost everywhere that you turned the camera, that would take extremely turbulent and muddy water, going over the mountain tops !
Great teacher sir. Thank you for your videos, very educational. I go threw west Yellowstone often, how beautiful.
Is there any chance that there could have been an inland ocean or large lake in the Bighorn basin at the time of this massive slide? I love your videos I grew up in Montana and remember the fascinating drive from Cook City to Cody via sunlight basin. Now having watched this video I hope to return and see it through the eyes of a geologist. Thank you Myron ✌🏾💪🏽🙏🏾
I love all your videos, I wish I had more of them to consume. I love how you engage the viewer with questions, your drawings that help explain it deeper to your calm yet happy and excited way of speaking. You are doing a amazing job explaining, and the fact that you are personally visiting the areas you are talking about, taking days, walking, filming is absolutely astounding. And the drone views are jawdropping. Truly a beautiful technology. I wish more people stumble upon your content. You deserve every view you get.
This is amazing. A wealth of information. I absolutely love everything about this video! Thank you for all the effort you put into this presentation. Best part, you don't take a whole 5 minutes talking about your sponsor or your Patreon supporters, or "hit like, subscribe and that bell". That kind of thing is a cancer on the Internet, so seeing a knowledge rich video like this with none of that BS is such a breath of fresh air.
I'm glad you enjoyed it!
Thank you again Mr Cook for all your hard work. Its obvious you've spent many many days, miles and muscles (the summit hike) to present all this extraordinary information. Keep up the good work!!
Many thanks!
Thank you
You're welcome
Having recently moved to South Africa where there is such interesting geology, I would love to have someone with your clarity to make it come to life. Your videos are excellent as you patiently build the picture and hold our interest.
The same hot spot under Yellowstone was under SW Washington, NE Oregon, and Western Idaho. Millions of years ago, fissures appeared and released Flood Basalt that traveled all the way to Columbia River. It buried parts of Washington, Oregon, and Idaho. I live in Central Washington. Numerous layers of Flood Basalt are over 1 mile thick. In some places it is over 2 miles thick. The Yakima River Canyon is great place to see many layers in plain view.
The deepest part of the Columbia river basalt formation is at Prosser.
Its 3 miles thick at that geographic point.
Shell, EXXON-MOBIL, and BP, performed exploratory drilling in several spots throughout eastern Washington.
There is a sizable crude oil deposit under eastern Washington.
I certainly hope that you have viewed Nick Zentners documentary on the Columbia river basalt formation.
Thank you for mentioning this.
@@TheErik249 Thanks, I live in Yakima and they drilled here too. Not sure how thick, but based on gaps carved by Yakima River in the ridges, see lots of Basalt. We only see the top several thousand feet.
@@TheErik249 I'm a big fan of Nick, he always amazes.
What did the flow fill to get 3 miles thick?3miles?
you have a gift Myron, thank you for sharing it.
Besides the Heart Mountain landslide, I recommend reading up on the recently-discovered Markagunt and Sevier gravity slides in Utah…they about the same size as Heart Mountain (~2000 sq mi displaced terrain). The Markagunt and Sevier gravity slides are thought to be related to inflation of calderas in the region during the Mid-Tertiary ignimbrite flare-up. Really interesting structural geology and fascinating pseudotachylites.
This is a great video-your work is really appreciated!
Question: does the detachment actually make a sharp angle (as drawn in the video) between it and the heardscarp of the slide, or is it actually more of a listric, curved scarp?
Thank you for your feedback! I have read a paper and saw a youtube video on those giant Utah slides...impressive. The breakaway fault for the Heart Mtn slide does have the sharp angle. I'm not aware of anyone describing it as listric.
@@myroncook Thank you for confirming that detail on the geometry of the breakaway fault. Regarding the Utah gravity slides-IMO, one lesson to be learned there is just how long the geology was passed over as just “weird rocks” or “volcanics”. Given the sheer size of these kinds of events, field identification can be difficult. Now that there is more consciousness of these kinds of enormous gravity slides in the literature, I expect we might find that such events are more common in regions with a history of silicic caldera volcanism/ignimbrite flare-ups, than previously appreciated. For example: I expect such gravity slides might also come to be found in the Bolivian Altiplano, associated with its Pliocene ignimbrite flare-up, in the Sierra Madre Occidental of Mexico, and perhaps even in older ignimbrite complexes/silicic large igneous provinces such as Chon Aike in Patagonia. It seems that the combination of rapid accumulation of thick volcanic sequences with the kind of regional uplift and oversteepening and destabilization associated with caldera resurgence could be a recipe for this sort of disaster.
I'll bet you are right. It sounds like you are into these systems...very interesting!
This was fabulous. I appreciate your making this video as clear as possible about things we can only imagine as we look at the evidence left behind. Blows my mind. Thank you.
Glad it was helpful!
Wow. Just found your channel. I eagerly await more videos.
Thank you for a very interesting presentation.Just ‘discovered’ your channel today and was very interested to learn about the geology in Wyoming. And see some of the places I have visited.
"the beans are above the frank"
Mr. Cook, Thank you so much for sharing your knowledge and enthusiasm with me. It is a wonderful presentation. I'm glad to know there is a teachers like you, and proud to say I attended your class today...
Thanks, again
So nice of you
Thank you so much for showing all of this Beautiful landscape. I absolutely love following you on all your hikes as it's something I've never been able to do. As always you've given so much information Just made my day.
What a delightful presentation. A few years ago, I stumbled upon the original paper presenting the CO2 pillow concept and was amazed at the speed, distance, and 2° angle. You have a gift in the way you present the delight of the discovery and the beauty of the earth. Thank you for using your time to give to others.
Glad it was helpful!
All I can say is Wow! What an informative and interesting presentation. Thank you so much for sharing your passion and knowledge!
Glad you enjoyed it!
Absolutely fascinating! I luv how you help make geology both easier to understand, and a fun, wonderfully interesting subject!
What an incredible time we live in that we can watch something so informative and interesting for free on the internet. Thank you so much for teaching us this!
Fascinating video, thanks for your efforts to bring geology alive. The time frame of these events is mind-boggling.
I agree!
I saw few videos from you, I absolutely love it, listen to your interesting education.I am 72 year grandma from Austria, living now in the USA, love this beautiful nature and the geological history about it, thank you!
Your videos have helped get me out of my depressive slump. Thank you for your effort
You are so welcome
You crack me up Myron - we are an artsy bunch. Seeing the detachment examples is so very excellent.
