The Triple Junction of Southwest Utah
Вставка
- Опубліковано 26 вер 2024
- In Southwest Utah near St. George, there is a unique “triple junction” of 3 of physiographic and geologic provinces. Those 3 provinces are the Colorado Plateau, the Mojave Desert, and the Great Basin. Join us on this tour around Southwestern Utah and you will learn how to "read the landscape" and see where certain features can be found, learn about what makes each province different, where to find some of those features, and why this triple junction is so special.
Would you like to go on a road trip to find places where this "triple junction" formed spectacular landscapes? Watch our two part virtual road trip that shows the way:

I am glad that it was mentioned that the Grand Canyon was not entirely formed from just the erosion the the Colorado River, but also from the uplift of the land.
Really? The uplifting caused to erosion
Or was it all ELECTRICAL SCARIFICATION?
@@timkasten7708 In a sense, yes. Without the uplift erosion would not have made the GC.
I'm a huge fan of Matt's Off Road Recovery out of Hurricane. I see all of these features in his videos and crave knowledge of how they were created. This video shed a TON of light on those curiosities! Thank you.
You're welcome and thanks for commenting. Yea, we see signs of Matt around town occasionally.
It's actually MORR that got me interested in this region - and therefore I'm watching this video
Nice video
The Great Basin is my favorite province (because I’m from there) but I can see the beauty in all the three provinces and seeing them mush together is really cool.
This is exactly the broad overview of the geology of the SW and Colorado plateau I was looking for. Very well done!!
Thank you! Glad you found it worthwhile watching!
St. George/ Zion National Park…..the entire area is just stunning and so picturesque. I just love it out there!
I lived in St George from 2013 until 2018. It was nice to see this fascinating topography once again. 360 degrees of "WOW"!
Thank you! Been living in Hurricane since 2016 and how I've learned about all this stuff.
@@BackRoadsWest1 Obvious you knew the area well; you had the correct local pronunciation of Hurricane city.
This is the best comprehensive tour of SW geology, I’ve seen.
🙏
Excellent, thanks for commenting!
I've lived in this area for 7 years now and have been fascinated that I can stand in front of my home and see all three of these provinces at the same time.
Funny, same here! Except, it's our backyard. It's part of our inspiration for creating the video. Thanks for commenting!
@@BackRoadsWest1 Wife and I will be moving to Washington Utah within the year... can't wait.
I've lived in various parts of the Mojave desert for 20 years and am always amazed while driving anywhere. Hurricane and the Virgin River are beautiful, Colorado Plateau is almost spiritual. I haven't been through the Great Basin much, nobody has been, but it is almost other worldly.
My favorite area to explore+travel driving the backroads+remote camping.
What everyone else has said plus;
I came through the junction at night having traveled from Washington a couple of years ago. My desert adventure. I traveled this area at night en-route to winter warmth in Yuma. I missed most of the natural beauty as a result.
Thanks to your video I'm going back. I now realize that this is the hub and culmination of what I've been looking for in a place to set new roots. No more PNW rain❗
Lots to see here! Thanks for commenting.
@@BackRoadsWest1 Yep. My previous comment was too limited, I left out that I'd stayed about a month near Cedar City out in the desert at Three Peaks Wilderness area. (I believe that's the name.) I'd never seen such a remarkable terrain and geology before. Even two years in lava fields of Hawaii got trumped. I became interested enough to make several visits to the local BLM geology office, a rockhound was born.
This channel popped into my UA-cam stream yesterday. This is going to be fun. I love Geology, topography & volcanology.
This is amazing. The geological explanation is second in excellence only to Nick Zentner (which is extremely high praise), but the visuals you created to help explain the narrative were second to none. Everyone involved in the creation of this video is a Boss. This is a veritable masterpiece compared to most youtube fare. Well done.
Thank you so much for the kind comments. I looked up Nick Zenter and remember watching a few of his episodes. Thanks for rating my explanation near Nicks. Comments like yours makes my labor of love well worth it!
As a fellow "Zentnerd"... I share your compliment. I'm only watching now because its a Wednesday, and no class today... Darn the luck.

South west Utah is truly breathtaking. I've been to Sand Hollow state park and the scenery was unlike anything I have ever seen. Thank you for making this video!
My pleasure! Thanks for commeting
just drove back to Denver from Las Vegas using i15 and i70, this video answered so many questions I had while driving and seeing all those formations.
This video drew me in with its stunning photography and pleasant narration about complex geological topics. Really well done and I can’t honestly believe that I watched a 40 minute video about rocks. That’s a huge compliment! 😂
LOL! Yes, that's a hard ask for people to watch a long video essentially about rocks. If you'd like to see where to go see some of the places in the video, see ua-cam.com/video/ITO3KsBTrjg/v-deo.html - but I'm sure you've already visited them.
Ausgezeichnetes Lehr - Video. Ich wünschte, wir hätten viel mehr davon. 🙂
Danke schön! Da Sie aus Deutschland kommen, wird Ihnen dieses Video über die Mosel sicher gefallen: ua-cam.com/video/jN2b60G5pPU/v-deo.html
Cool photography and production, thanks for the insight
Thanks for this very enlightening documentary. In Fall of 2009 I dog-sat for a friend in New Harmony for 6 weeks. Wish I had known all of this back then. However, not knowing anything … one cannot escape the immense stunning beauty and great drama of this area! Despite it being a nasty icy wind tunnel, it felt very sacred to me. I used to take the dog for a jog thru the sage brush hills … while the West side of Zion park framed the landscape … what an amazing 6 weeks!
Glad you enjoyed it! Thanks for commenting.
This is wonderful! Well laid out and explains much. Well done.
Love this channel! Thanks for making this content 👍👍
Brilliant explanation, astonishing pictures and illustrations, just great upload! Thank you!
Glad you enjoyed it. Thanks for commenting!
I am headed to Hurricane for a vacation at the end of this month. This video only made we want to see more! Thank you for the details!!!
Thanks for the comments. Stay tuned for more video tours of the SW Utah area.
I live in st George right where he’s talking about. This video came up randomly too!
It is the best area I’ve ever lived in
Well, that's where I live! Yup, lots of interesting geological stuff going on here.
I watched this before and after my trip to this area and it was very informative. Thanks!
Fascinating, excellent video with really great animations and visuals accompanying your explanations. Well done and keep them coming please!
Thanks much!
Wonderful presentation, thank you!
You're welcome and thank you for commenting!
I love this video! I lived in Boulder, UT for a few years and it was lovely catching up on some spots you outlined, such as Strike Valley Overlook and Powell Point - however, I'm confused!
I don't believe Powell Point can be the highest point on the CP. Check out nearby Boulder Mountain at approx. 11,300ft. It's part of the Aquarius Plateau that sits atop the Colorado Plateau. Powell Point kind'a gets overshadowed by it since it sits 'behind' the Straight Cliffs of Escalante.
Thanks for commenting and finding this inconsistency in the video. Both you and the video are correct. Funny, I was just refueled in Boulder on my way to Torey last weekend to pickup a one-way tour group. So, you're right, Boulder Mtn is higher (elevation wise), but it consists of material from a volcano that occurred after the material of the Colorado Plateau formed. Same is true with Brianhead Peak, which is also higher than Powell Pt. I could have been more clear on the video at the cost of making it longer (it's already way too long - but people are watching it) is that Powell Pt is the highest formation (Clarion formation i.e. Bryce, Cedar Breaks) of the Colorado Plateau. Case in point is at Cedar Breaks where you see the white and pink Clarion and then right on top of it is the volcanic material of Brianhead & the Markagaunt Plateau. Hope that helps!
Great video as always! You make such fantastic videos, very easy to get an overview of the area something that otherwise is hard to do from just a maps or description and no other videos comes close to this. So much detail and yet so easy to follow. Thank you for your hard work on these videos. I follows your El Cajon pass and San Andreas video for my last drive to LA from Seattle down the 395 and made a few detours in area through Wrightwood.
Thanks for the kudos. I wish I had more time to travel and create more videos!
I wish I had stumbled on this vid a few weeks ago! My husband and I will be visiting the Grand Canyon area next month and would have included the Triple Juncture in our plans. Plans are now etched in stone. Maybe next year we can visit the Triple Juncture. So many photo ops and not enough time! And I too am a Nick Zentner fan, and you are right up there with him!
There's a lot to see here. Glad our video pointed out some things. You can easily spend a week in this area and see all the beautiful landscape.
Great video and I can't believe I hadn't seen it before now. I live in Washington, up in Green Springs near Red Cliffs NCA and absolutely LOVE looking out at all of this beautiful landscape on a daily basis. Really cool to learn some more about why things look the way they do. Thanks for the video!
Glad you enjoyed it! LOL, I was hiking near Grapevine Spring off Washington Pkwy a week ago. Be sure to watch the tour: ua-cam.com/video/ITO3KsBTrjg/v-deo.html
Super clear and easy to understand video. Bravo!!
Thank you and thanks for commenting!
Thanks! Very keen on geology! Love it!
Excellent production and fascinating geography. I enjoyed every minute. I have visited all three deserts more than once, but I still learned a lot from this video.
Thank you!
I live in the St. George area and a friend and I travel three or four times a month just to explore the area. Zions National Park will knock your socks off--and so might the entrance fee of $35. Fortunately, I have a lifetime senior pass for the national parks. But if a person has never seen it, it's worth the money. This is a great video and one I'll go back to constantly to plan future trips! Thanks, BackRoadsWest1. Oh! My friend and I always take the back roads. For example, rather than I-15 we travel on old 95.
I love this video. You do such a great job explaining geology with the imagery, graphics, and annotations, and placing us the viewers in the settings as if we were there. Geology comes alive with this video.
Thanks a bunch for the kudos. We're glad you like it - that's what we're aiming for! Thanks for commenting.
Have watched this before but it is so informative and interesting that it probably won't be the last time either! Thanks; you have such a great voice and I learn so much from your vlogs.
Thanks for commenting. Yes, there's lot of information to digest. I even have to watch it over occasionally!!
Have family in Leeds and I am always exploring when there. The video gives me so much more to look for and ponder when out and about. Thank You for this!
Our pleasure! Hopefully you'll look at everything differently now on your next visit.
simply EXCELLENT !! Thank you for your time and effort to create this masterpiece.
Thank you! My pleasure!!
I have learned so much by watching your most excellent Video presentations. I am much appreciated, Thank You......
Been thru there a couple times, interesting drive for sure...
What perfect timing for UA-cam to recommend this video to me. My wife and I will be travelling to St George for the last week of September. This will help tremendously with our explorations of the area. We live in NC and have nothing to compare with the desert southwest.
Enjoy the trip. Hope you learned something. Thanks for commenting.
@@BackRoadsWest1 Thanks! I'm also checking out some of your other videos of places we might wish to go while we are there. I rode a bicycle on route 50 on my coast to coast bicycle tour five years ago and definitely wanted to show my wife some of it as well as explore some areas that I did not get to see while passing through. So a week in St George followed by a week in Sedona.
@@jerrymiller276 well, there is lots to see in Utah. But you're starting in a place where there's lots to see. Have fun!
Welcome! I've lived here all my life, and I wouldn't want to live anywhere else. Zion National Park is a must see. And Bryce, if you want to make the 2 and a half hr drive.
Your video is amazing!! I am so happy that I found your channel. We will go to this area this summer. I am so excited to check this area more. I will share this video to my husband, and I will watch this before and after the trip! Thank you very much!
One of my fav areas to look at on Google maps or Google earth! One of the coolest aerial views in the US of natural landscapes just east of Hurricane UT, the (4-corners region) it forms a silver tip red fox bed down! ❤️
While I am planning my Utah trip, your video popped. Since I would like to stay in St. George for two days, I clicked in. It is so informational! First time to know those geological terminologies. Would like to watch it again to make sure I can most things you mentioned in your video.
Thank you! Enjoy your trip here. Hopefully you discovered our other videos on places near St. George. Check out our blog with other travel ideas that may be within your travel distance: www.backroadswest.com/blog/category/utah/
Outstanding visuals, and just the right amount of geology. Actually many geologists don't even understand or agree with what's going on. Lots left to figure out about this beautiful region.
Thanks for commenting. You're right, I'm told that many geologists don't agree with different theories. We certainly will never know what really happened. It's all an educated guess. But at least the geology gives us a lot of pieces to the puzzle and it's just darn fun to think about.
That area is stunning. I've watched some other UA-cam videos around there and wish I had the nerve to move. This was very informative.
Thank you. We had the nerve, we moved up here from So Cal.
So nice video, so clear narration. Thank you for your video. I'd like one day to go and see those magnificent places... Btw I am watching you from Russia
Thank you! Glad you enjoyed the tour and presentation. I'd also like to see the landscapes in Russia some day, especially the Kamchatka Peninsula.
After viewing this outstanding video lesson, I wish that I had had time in college to take a course in geology. I am now self-teaching and your videos are very helpful. Thank you.
If it helps, we're "closet geologists"; self-taught after reading a bunch and taking several classes. It's fun to know what you're looking at out there.
I went from Las Vegas to Zion NP in 2015. You have to go through St George on the way. I saw St George's geology and wondered what on earth formed this bizarro set of cliffs. Now I know! It is an amazing area for sure.
Yes it is. Thanks for commenting. Our video tour supporting this video and showing where to see all these places will be released shortly.
Amazing and wonderful video. So fascinating.
Glad you enjoyed it!
Southern Utah is probably the coolest place in the us
But in summer it is among the hottest places.
Amazing Video ....love this whole area ...all 4 deserts of the southwest and the Colorado plateau are breathtaking ...have you made any videos that look at the Mogollon Rim area
Very nice production. Thank you. I live on the southern edge of the Mojave Desert on the San Andreas Fault which is the ecotone between the desert floristic provence and the california floristic provence. Talk about genetic diversity. The geological activity in my region is spectacular. I want to move out of California but this desert doesn't want me to go. It is constantly finding new ways to show me how beautiful it is.
Thanks for commenting! Yes, we used to live in the Victor Valley near the SF Fault, now we live on the other side of the Mojave Desert next to the Hurricane Fault. Same desert, but much nicer. So many nicer things to see here instead of the increasingly crowded L.A. area.
@@BackRoadsWest1 sure thing. Thank you for the video you did a great job. I am thinking Of fleeing in October to that area I like western cedar city/ rural iron county a lot. Excited to visit again in April for recon round #3
That was incredible!! Keep making videos!!
Thank you, I will, and thanks for commenting!
Great work!!! Thank you.
You're welcome. Thanks for commenting!
I totally appreciate the correct pronunciation of Hurricane. Easiest way to spot a newbie to the area is the way they pronounce our city name. I work out in this area. By Zion National Park. I learned some from your video. Thank you.
Funny you noticed that. Living in Hurricane myself, when I released the first version of the video, several people said I should add what you saw. I initially didn't want to include it because then it revealed to the public "our secret" of spotting out-of-towners.
BackRoadsWest1 are you still a southern Utah resident?
I was gonna say the same thing about the pronunciation of Joshua tree. The u isn’t silent
I thought it was Josh-you-a Tree.
@@StonemanRocks no. The world is not wrong. Nor are we. It’s the local pronunciation. Lots of words are pronounced differently in different locales.
Well Done! and Thank you. Very clear!
Glad you enjoyed it! Thanks for commenting.
This is great work! I note that the Great Basin, from a hydrological perspective, includes part of southwestern Wyoming. The Bear River, which originates in Utah, flows from Utah to Wyoming to Utah to Wyoming to Idaho to Utah and thence into Great Salt Lake. The latter, of course, is in the larger endorheic Great Basin. The headwaters of Smith’s Fork of Bear River extend to the vicinity of Triple Basin Divide (in Wyoming) which is that point from which waters flow into (i) LaBarge Creek > Green River > Colorado River > Gulf of California OR (ii) an unnamed tributary of Smith’s Fork > Smith’s Fork > Bear River > Great Salt Lake (Great Basin) OR (iii) Greys River > Snake River > Columbia River > Pacific Ocean. A different subspecies of cutthroat trout are found in each of these three watersheds within miles of each other.
Thank you and thanks for taking the time to comment.
I just yelled out "THANK GOD FOR DRONES!!" these shots are amazingly well visualized and explained clearly! I love this way too much!
Thanks for the comment. Yes, drones have certainly opened up a new dimension for photography/videography.
Wow great video.. think I better check out some more of your channel!
Thank you. Enjoy the tours!
Thank you for this explanation!
Stunning.
Thank you
Great video and very informative. Tis video has helped me understand ore about the are where I live, Hurricane, UT.
Excellent! Funny, I live in Hurricane too and was definitely the inspiration behind creating the video.
@@BackRoadsWest1 I have been to the top of Hurricane Cliffs, Black Ridge, the very edge and it is a very impressive overlook but a very scary place to turn your Jeep around. No need to do it again.
@@ectosports Black Ridge - I assume by the antennas? If so, yea, that is a rough road. It's getting worse now with all the ATVs going to T-ville Falls. Nonetheless, yes, there are some great views up there.
I'm such a geology nerd that this vid brought a tear to my eye. Well done! Bravo! Shared!
Glad you liked it! Thanks for sharing and commenting.
Glad the gods of UA-cam recommended this. Geology? OF UTAH??!!!
OH HELL YES!
And how appropriate: heading to St. George next week!!!
Can't wait to get me a good dose of Navajo Sandstone soon...
Oh, hell yes!! Hope you enjoy your trip. There's a lot more to enjoy than Navajo Sandstone, maybe a more dosages of the corrugated Moenkopi...
@@BackRoadsWest1 for sure! Yes, we will indeed. Thanks for the encouragement.
Great work! Thanks!
You're welcome. Thanks for commenting!
I live in Hurricane and love to see these formation every day!
So do we! Except we have a look at all those great formations over the rooftops of La Verkin.
Now I have to look up the root of “hurricane”. (I live in Florida).
Well done, thank you.
Thank you for commenting
A Magnificent Presentation. So much to absorb and understand. I Love Geology. Thank you for this.
I live in Hurricane. Can't believe I get to Mt. Bike and explore all over in this rugged creation every morning. From Hurricane Cliffs, to Confluence Park, to Gooseberry Mesa and beyond it's an every day experience for me. Don't even mind all the rattle snakes.
Too funny, I live in Hurricane too and ride the Hurricane Cliffs trails when I have little time, or Wire Mesa when I have more time. The scenery has definitely been part of the inspiration for making this video!
@@BackRoadsWest1 Cool. Perhaps we've seen one another and never knew it. I ran into around two-hundred high school kids on Saturday and rarely ride without seeing at least a half-dozen riders. Thanks for the great video. Very educational. Now I'm watching all kinds of geological videos. Benjamin Burger, a USU geologist has produced a lot of them. I thought yours was more informative, however. Good work.
@@greenlightreading6975 Perhaps we have. Lately with the heat, I haven't been hitting those trails, but limit myself to around 8am on a quick 1 hour ride thru Cinder Knoll (if you know where that is off 600 North) just to get exercise. Thanks for the kind words on the video(s). My wife and I (mainly me) enjoy doing it and it's a great outlet for our photography. I'll have to lookup the USU geologist on UA-cam - thanks.
@@BackRoadsWest1 I pass by the Cinder Knoll going and coming. Between 6:30 and 8:30. I'll hike there when the temps are cooler. I'll be watching your other videos soon.
Is there really a lot of rattlesnakes in this area??
Excellent 😉
Thank you!
We're (hopefully) headed to Snow Canyon State Park near St. George and then to Whitney Pocket and Little Finland next month. Your videos have been invaluable in our quest to find out-of-the-way places to visit. Thank you 👍
You're welcome! Glad you enjoy them.
I live in Hurricane. Thank you for this highly-informative video!
You're welcome. Glad you enjoyed it. Too funny, I live in Hurricane too! Part of our inspiration for making this video.
Thanks for this great video
You're welcome and thank you for commenting.
I live in the Kayenta community of Ivins near Snow Canyon state park. Though the community beneath the red cliffs is called Kayenta, I’m inclined to think that the nearby mountains are rather from the Navajo formation after viewing your video? Are any other formations represented in Snow Canyon besides the Navajo? Just curious.
We actually live in Hurricane and one of us works occasionally at Coyote Gulch. Snow Canyon is pretty much all Navajo, with your community's namesake, Kayenta, towards the very bottom. Roughly the bottom half of the hills behind Kayena is really Kayenta formation. Unlike Entrada, Kayenta really has rock named after it. If you'd like to know more about Entrada and how far it is from St. George, see ua-cam.com/video/6jt-yRosxE0/v-deo.html
I love this kind of stuff. Geology has always fascinated me. One question…
Why “Josh-a tree” rather than “Josh-ua tree?” Have 98% of us been pronouncing it wrong all this time?
Thanks for watching. No, you're pronouncing it right. It's like tomato or tomata; data or daata. My pronunciation is a shortcuted version. You're saying it phonetically correct.
I wish Pah Tem;e mineral hot springs spa was still open. I used to travel there every weekend fo hang out and enjoy the rural climate of southern Utah. it was the best mix of Starbuckian suburbs and rural southwest i've seen anywhere.
We've recently went on a tour there and it makes a lot of sense why it's now closed.
BTW, I also watched your Gold Butte video, Will add Little Finland to my list. :)
Fun fact! At 38:50, those homes started falling off the side of the hill a few years later.
Very well done and interesting especially since I live in St George.
Thank you. Well, the video was inspired and produced by people in Washington County.
This is a great explanation of the geology in the area, much better that other presentations on UA-cam by academians. Thanks for sharing.
Glad you enjoyed it! Thanks for commenting.
Nice video -- great overview of the area. I won't nitpick/debate some of the pronunciations as others have, but.. Capitol Reef is with an "o" not an "a". It's named for the Navajo Sandstone there which resembles capitol (building) domes one might find in a capital (city). 👍
Thanks Jamal. Good catch! I think someone pointed that out to me a while back but it was too late to republish the video. I wish UA-cam would allow one to update a video rather than upload a new one and lose all the comment history. And Jamal, what an honor for you to be commenting on our video! We really enjoy watching your videos about hiking thru places in Utah we will probably never get to. Your use of cameras is superb! My wife and I being photographers wonder how you capture that stuff all by yourself during your extreme hikes. Whenever you are passing thru the St. George area, please drop us a line as we'd love to buy you lunch or dinner and chat about mutual travels. We live in Hurricane.
@@BackRoadsWest1 Haha -- thanks! I didn't see it mentioned yet, so I thought I would make the note. Glad you guys have enjoyed my videos and yeah... I too very much wish UA-cam had a way to make small edits w/o re-publishing. I have many mistakes in my videos (typos, wrong place names, mispronunciations, etc.) that I HATE being forever embedded. Even a pop-up "notes" track would be really useful (other than the caption system.) Would be great to meet up for a meal at some point -- thanks for the offer! I'm actually headed to southern Utah later in April for another big hike, but prob won't be stopping in that area as my plan is to start over by Bryce and this time and hike east. Cheers!
@@Acrossutah Too funny, we also have a video on Cathedral Valley and I saw that I spelled it both ways (ua-cam.com/video/jeZU2WHjUDI/v-deo.html). Thanks to you, I just made the correction. But I don't want to watch the video again to see if I spelled it wrong there. I will at some point! It would be fun to chat with you on various levels (Utah and video production). If you're driving up I-15, we'd be happy to meet you at one of the off-ramps with an eatery. Let us know - email is best for me cliff@backroadswest.com
Great video
Very well done video
Thank you
I love Hurricane Utah. My big sis lives in between quail lake and sand hollow. Lots of cool places to explore. Dixie rock is awesome at night in st George and mesquite isn’t that far for gambling and fun.
This was very interesting. Thanks so much! It coincides with me reviewing old geography texts and reading new ones in preparation for a month-long (spring 24) motorcycle camping trip across S Utah
You're welcome! Thanks for commenting. We'll be releasing a tour video of this area real soon. Stay tuned!
Very well explained. I agree with evil cam...your geological explanation is second only to Nick Zentner. Keep up the great work!
Thank you very much! And thanks for taking the time to leave a comment.
The scene at 18:47 is known as "Wedge Overlook" in the San Rafael Swell south of Price, Utah and seems a bit unrelated to the text. Great video and discussion of geology.
Thank you. Good eye! Most people wouldn't have recognized that. I used this scene, simply because it was another vast deposit of Navajo Sandstone I'm able to confirm while not using yet another shot from Zion. I also didn't want to use a shot from Valley of Fire with jumbled Navajo/Aztec.
If Southern Utah is a geologic triple point, then is that area considered seismically active? In many other parts of the world where you have geological triple junctions like this you have active volcanoes and frequent strong earthquakes. Most people don’t associate Southern Utah with earthquake danger. However, I would surmise that a violent earthquake is at least a remote possibility in Southern Utah with these types of geological forces at work.
Hey Hurricane0721, do you live in Hurricane? Because then you too would be familiar with the Hurricane fault. The Southern Utah area does experience earthquakes. St. George had a magnitude 6 about 20 years ago. However, faults, such as the Hurricane, show little movement over the past several thousand years unlike faults related to the San Andreas. So it's not as geologically active as California.
Good question. The presenter using the term as a geographic delineation and not the classic tectonic New Madrid fault and mid-east function.
Great
nicely done!
Thanks!
Wow ! What a wonderfully made video. Thank you!
You're welcome and thank you for commenting.
thanks it was very interesting
Glad you enjoyed it
Of I drilled a core sample below the sandstone layers described here in the Colorado Plateau, what kinds of rocks are below them?
All kinds! I'd recommend taking a geology class...
I live in the area so it answered a lot of questions. Is there a big fault on the Southern Nevada California border? In other words should I be buying earthquake insurance?
Thanks for commenting. Basically, wherever there is a mountain, there's a fault. Even the most insignificant faults in So Cal caused some of the biggest earthquakes.....and none of them in modern history were on the San Andreas, or the Hurricane Fault for that matter. You just never know...
Excellent! My only suggestion is in the early descriptions of the formations you could have mentioned the lithologies of each and why that results in the formation of cliffs or slopes.
St George is surrounded my some incredible landscapes.I thought it didnt make sense that this was a city and not a national park.Its been 17 yrs since i was last there and the housing tracts were booming.I can only imagine how bad the place looks now .
Well, I'm sure if it were up to some people, all of Utah would be a National Park.
You just can't beat Nick and his chalkboard and bowtie. Having said that this is one of the best geology presentation I have seen on UA-cam . The one thing I have a problem with is you and all of the other geology videos including Nick Zentner is relating geology of our world to Pangia. Its is impossible for me to get a mental picture of the monumental forces that make up our planet. I think anything past 50 to 70 million years is the end of the breakup of Pangia. Hope to see more.
Thanks for the kudos! LOL - you know every geology presentation we've been to starts with the "super-continent" Pangea. You're right. I don't think we discuss Pangea in our video; it really doesn't fit (no pun intended).
