I'm watching your video now sir but I am genuinely wondering how did you get the link you've posted to work?? I ask this because RU-vid doesn't allow links posted to work anymore allegedly due to scammers and hackers so Google says! I honestly don't think it's due to that at all and more due to links take people away from RU-vid and less people here on RU-vid then there's less people watching their ads! Less people watching ads means less money they make! Idk maybe I'm wrong but I seriously don't think so! There are some links that slip through and work like yours does but not very many at all! Even old links have altogether for the most part been disabled as well! If you could please get back to me I'd really appreciate it please and thank you!

Your diagram in this video tells me so much more than just seeing maps of faults. Never knew there are divergent plate boundaries through there…thanks!

@Firebuck 3 месяца назад

The releasing and restraining bends were really interesting. I've heard that plate tectonics is a pretty recent science (1960s), and this discussion made me wonder how the details were worked out. Imagine being the guy that figured out the mountains over yonder were formed by the same fault movement as the volcano over here. Just a right turn vs. a left turn.

Hiking Joshua Tree countless weekends sparked my interest in geology decades ago. Only now, the pieces of the puzzle are revealing themselves. Standing atop San Jacinto Peak, you get a sense of the magnitude of forces at work throughout this area. I always wanted to know the geological story. Thanks for your help. The diagrams are indispensable. Thanks for the time you put into them.👍

This was very informative. I grew up in El Centro, and experienced several large earthquakes on the Imperial fault. It’s always great to learn more about the Valley geology. Thank you

@mindysdad3110 3 месяца назад

I vividly recall the earthquake swarms there in the early '80's. I was living in Imperial at the time and there was quite a bit of damage to the old downtown buildings. Aside from that; Professor Jay Van Werloff of IVC brought attention to the mini volcanoes (mudpots)of Salton Sea years ago; he was passionate about the local geology and anthropology.

@user-zq3iz3zn5m 2 месяца назад

I was supervisor on a drilling rig at the southern end of Salton Sea in the 80s. On our days off, we would explore the out cropping and come back with chuncks of obsidian larger than 1 cu. ft. On the border, we would find very tall outcroppings in the Anza Borrego with some pretty good garnets. Some private jewelers would pay 50 to 100 bucks a piece for the best ones. The desert Want a wonder filled environment.

Very nice discussion on how deflections of the strike slip faults can alternately create areas of extension and resulting basins or compression and resulting mountains. This is one of the areas of the western US that I haven’t had a chance to see first hand and I know little about. After this video, I know a little more. Thank you.

@hestheMaster 3 месяца назад

The geological features of Southern California are rather unique and you took great time in explaning why things are the way they are there Shawn. And I thought this place was a dead zone of activity. It is very much not so. Another YT'er was here exploring and there were huge piles of pure unweathered Obsidian where she was. Was amazing seeing both views of roughly the same kind of geology out in what looks like the middle of nowhere. Thanks again for this cool visit.

@mikeladley5149 3 месяца назад

I lived in San Diego for 36 yrs, been to the Salton Sea as a kid, but never knew of Obsidian Butte. What a cool place! When I was rockhounding in Oregon, I got some nice specimens in Davis Creek in Northeastern California, along with Sunstones near Plush Or, and Opal in the Virgin Valley near Denio Nv. I'm the guy that lives 18 miles from Taal Volcano Philippines. Miss the rockhounding sites of the Western US. Thanks for the video's and their insight into Mother Nature's impact on the Earth. 👍💖

The old timers called that area black rock. When the water was up to the rocks. Was Great fishing area for corvina, croaker, sargo fish. Because the water warmer in the winter & spring from heat bubbling up from underneath.

My son lived in San Diego for 8 years and while on a trip to see him and family, we made a road trip to Obsidian Butte at the Salton Sea. I actually mailed about 50lbs of rock and obsidian samples back to North Carolina by the USPS for $38. Was cheaper than a $50 airplane carry on bag. Keep exploring and learning my Friend.

@alisalavine1052 3 месяца назад

Great content, Shawn. I learned so much. I'm forever confused by the different types of faults. Hybrid faults are even worse. But your "art" really made it easy to understand. I was born and raised in Southern California. At 22, my young family was uprooted to Kansas and decades later, I'm still in Kansas. It wasn't until about 10 years ago that I even heard the name, Salton Sea. Crazy, right? It's really cool to be able to add some geological history to such a weird place. Thanks, for taking the time to teach this 50something year old in an easily digestible format.

@gunningopher 2 месяца назад

I've been playing my whole life and working as a land surveyor off and on in the Imperial Valley for 30+ years. This was such a great description of what is going on in that area and was at a perfect level for a land surveyor to understand why our geodetic control is so challenging there. I'm going to share it with our younger surveyors. I kind of knew most of this stuff but you really put it all together just the right way.

I've read (Economic Geology (1967) 62 (3): 316-330) that one geothermal well there produced 2 to 3 tons/month of siliceous scale that was 20% copper and 6% silver. The ore minerals present included bornite, digenite, chalcopyrite, chalcocite, stromeyerite (AgCuS), and native silver. This could be considered a model for the formation of ore bodies.

Thanks for this video! Another good one. Net time you are down there, consider hiking spectacular Painted Canyon, just about 60 miles north of Salton Buttes, northeast of the north shore of the Salton Sea. Visible offsets on faults in young sediments (Pleistocene, Pliocene) and old metamorphic rocks (Proterozoic), flash flood deposits, slot canyons, seasonal wild flowers, and more. Outcrops there illustrate most of a geology 101 course!

What drew me to it was the biology history of it and in particular the beaches composed of fish bones! Quite a sight to see and when the wind was right, to smell. I guess that the Colorado River deposits account for all of the rich farmland in the Imperial Valley.
