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 TH-cam 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 TH-cam and less people here on TH-cam 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!
it used to be the best place to go fishing... Corvina fish. ...they make great ceviche...
You often joke about your drawings, but they are VERY helpful. Thank you.
I love the cartoon diagrams too! I pause and study them for a few minutes. They're really helpful.
@@MyMemphisable Geologic mapping itself is an exercise in cartoon-drawing.
I agree! 💯
I don't care about geology,
I'm just here for the drawings :)
@@jeebusk set up some merch😉
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!
Outstanding Shawn. I learned a lot. I appreciate your organization and the cartoons. “Tell them what you are going to tell them, tell them, then tell them what you told them."
My feelings exactly. Just not able to express it so well😎
@@sonjo2419 Supercalifragilisticexpialidocious! Eh?
Found many pieces of knapped obsidian and arrowheads in the Poway Valley area of San Diego County... Was told by 'experts' that the obsidian came from the desert tribes who traded with coastal tribes. Now I know where they got it! Thanks!
Eggzactimatly!
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.
Anywhere I have moved to in my 71 years, I had a burning desire to learn of my local geology and how it came to be!
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.👍
The map you made is very helpful..and then to actually see the physical look of the rocks and terrain really helps geology be understandable.
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
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.
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.
Lived in the Imperial Valley for several years and we had earthquakes when the weather changed from cool to hot and back again. Pretty amazing area, geologically.
@@susancuenin2137
Yes miss. And hot is hot. Below sea level. Takes really different and hearty folks not only to live in the desert but to love it as well.
😉@@mindysdad3110
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.
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.
Oh filling great gaps in my knowledge and understanding . Thank you so much.
Great video. I can now say I have walked over some of the same geological area as you have. 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.
Did you knap it?
No, I don't do any knapping. I use rocks in a geology/rock presentation I do for Elementary age school kids on a routine basis. I'm just a RockHound that shares the things that God created.
@jayculp7530 That is wonderful! By far, a more important use of the rocks.
I actually did a Presentation yesterday for 15 adult Special Needs students at a local Community College.
@jayculp7530 As a retired sp Ed teacher I am delighted by this.
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.
Cheers Shawn, Nice video and Great information, JH 🙏🏻✌🏻
I love the Salton Sea! Lots of history with a storied past! Please do another video on it!
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.
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.
Thanks so much.
So interesting! You are a great teacher. Especially your explanations about the faults. When I last went to that area it was to bird watch. (Tilapia bones, fish were dying all around the shore) Thank you so much!
Thank you for that nice video.
I haven’t been to that particular spot so I watched with interest.
Since you are a geologist, you understood the geology there quickly.
As I am not a geologist, it has taken me years to understand this wonderful area.
Every time I get to drive through or visit that area I learn a little bit more about it.
the developing "divergent plate boundary" discussion with its volcanism was eye-opening to me... never heard that before. thanks.
I'm loving these road trips! You are fascinating!
Thanks!
Thank you for supporting geology education.
Professor, thank you so much! I am getting more interested in earth sciences, with quakes, volcanoes, tectonics and your channel has helped me much.
Love your maps and explanations of this fascinating area. Thanks for the education and keep up the great work Shawn!
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!
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.
Finally I understand how normal and reverse faults develop from transform faults! Thank you!
Cracking open and seeing that bright shiney obsidian was just lovely.
Wow! This video is loaded good information! A great combination of field trip exposure and classroom lecture is showcased. Thanks for the effort!
Another fun episode. Gotta get there sometime soon. I'm one of those who are enthralled with obsidian. Fun stuff!
Very well explained and demonstrated. You have wonderful teaching skills.
As a new resident of the area, thank you for the great info!
This video is beautiful with the light patterns on the rock
Wish I had seen this before my recent road trip through this area. Very informative.
Grew up in the San Bernardino mountains, & have had quite a few questions answered in this video that I have had swirling in my head for years! Grew up in Lytle Creek to be exact. ❤
I wish I knew more of where that name came from!
Thank you Shawn, I wish I had more geology background on the visits that I have made to the Salton Sea in the past. 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.
I had a geology class at Long Beach City College back in the day. Field trips around SoCal to view the myriad geological wonders were fascinating as well as educational.
Great video. Such a complex and interesting tectonic setting. Nice diagram and explanation. Love that Pumice and Obsidian mix.
So beautiful the volcanic dynamics .
Thank you for another fascinating video. Your teaching style makes it easy to understand.
A great video in an amazing location! Your diagrams, artfully held in place by cool rocks, 😊 made the complexities much more understandable. Never apologize for your hand-drawing ever again! There’s so much to learn about the Salton Sea area, and I hope you’ll make that extra video about it. Living in Minnesota, I hadn’t heard much about that area. Now I want to know a lot more. Thank you SO MUCH!!!
that's so cool. i had no idea we had volcanoes in that area. i'm fascinated by our little ecological nightmare and appreciate you sharing your expertise
BRAVO ZULU! Excellent commentary and such useful information. Cheers from JT.
I've wondered about this area for years. Thank you very much!!!
Really enjoy these educational videos. You project well and are easy to understand and follow. Very appreciated. Thank you.
I shared this video with my son. I used to live at Salton Sea so I perked up when I saw the title. He thought it was so interesting he took his 11-year-old daughter out on a weekend trip from San Diego to see area. Thanks so much for the great info!
Thank you so much for the diagrams (cartoons). They help me so much more than any map of the area!! I'd love for a more detailed description of the Salton Sea. Great video!!
Born and raised in the valley. Never knew we had volcanos 🤯
Damn video games
I've lived in Southern California all my life ( I'm now a senior) and have always been fascinated with it's topography. Thank you for connecting a
lot of dots for me I never knew about. The California desert is one of the few places in the world where you can climb to the top of a hill or mountain, look out, and actually still see how the ancient land was formed. The vastness of it and the powerful forces that created it is quite overwhelming.
I'm 59 yrs old , and realizing I should have been a geologist. I'm fascinated with this stuff!
Great job explaining the Plate Boundaries and their implications! Thx!
as third gen Ca our family Gave our Salton Sea property to the County, I noted How Clean this area IS! no Trash! I frequent an area just Noth near the summit Loaded WITH TRASH! very sad to see after growing up in our local deserts.
Totally awesome, Shawn...
One of your better ones Shawn, LOVE IT!!
Love your very clear explanation
Thanks Shawn. Definitely on my "must visit' list.
Thanks Shawn.. Seeing and learning makes me want to go visit all the geology. Hopefully I can remember. 😎
Excellent show…Thank you Shawn!
Great video and an incredible place. Thanks for the view through a geologists eye! Fascinating!
I live right next to the Transverse range. Thank you for your explanation of why they are there.
Thankyou shawn, what a fantastic vid really enjoyed it 👍
Thank you! Wonderful video.
I'm in Washington, but the way you explain strike slips, and how volcanoes occur at the bend in the fault just blew my mind as I saw the north Cascades and Juan De Fuca/ NA zone in my head.
In thinking Washington is at a lot more "fault" than most geologists realize.
This geology is awesomely constructed. Total vertical extrusions, layering, and banding ...
I love these videos! Thanks for sharing! 😊
Excellent description and diagrams, really easy to understand thank you so much, I too am learning so much. Watching you climb over the rocks brings it all alive.😊
Thank you so much! Love seeing it and hearing about the area!
thank you, great video from the field
Excellent video. Thanks for posting.
Fantastic episode Shawn. Just a short drive from my place. Definitely on my "must visit" bucket list. Thank you!
Wow! That was a great explanation of the area. You put it into a whole new perspective for me.
Great explanations of the geologic processes that have happened and continue to happen in this region. I live near this area and I really appreciate the detail you went into. Thank you for making your way down to Southern California and doing some exploring around here!
Thanks. So much Shawn for your excellent explanation of what’s going on geologically around Yuma, Arizona.
Keep them coming
Fascinating and enlightening. Thank you.
Really excellent episode
Great video, I really enjoyed.
Great summary. Love those rhyolites. Thanks for highlighting the spherulites in the obsidian. Keep up the great work. Rock on!
Great explanation, thanks so much!
very cool. thanks. great explanations!
Good work Sir. Learned a lot from you.
Thx.
Thank you for this vlog. Amazing! I know there is much more to learn about the Salton Sea.
Thank you for a great explanation!
Great video with wonderful hand-drawn graphics!
This is Remarkable Shawn . Thank you . Liked and Shared :) QC
Great explanation, thanks! I was out there last summer and collected some really nice samples of obsidian.
Enjoyed the very informative video & helpful diagrams!
Watching in February 2024. Now livin in Redlands CA, in San Bernardino County. Thanks for the info. Great work.
Wow. So cool. Thanks professor. I really enjoy your classes. I really learn a lot.
Always interesting. Love obsidian. Thanks Shawn.
Enjoyed your video about the geology of the Salton Sea. You inspired me to make a trip out there.
I just "stumbled" upon this video and loved it! Im hooked!!! Wanna see more!
I love ❤geology and you too professor👨🏫 🤜
Neat, thanks for doing this.
Another well explained educational video. I love them.
Thank you for this video I learned a lot from you. You definitely clarified things I didn't know I was missing until now hope you make more...
There is a massive amount of geologic history surrounding the Coachella Valley. Excellent video and enjoyable to learn from.
Thanks Shawn, great video. I was wondering if you were planning on making a video about Walker Lane?
Another great explanation Shawn, Thank You, You can't live in California without appreciating the varying Geology that surrounds you!
