Southern California Geology | Gabbro & Pegmatitic Dikes

Plant and lichen notes: 4:17 Encelia farinosa (brittlebush) white plant in background, also lots at 14:16. 6:15 Acarospora socialis - green lichen on rock, also lots at 8:06. 8:45 Xanthoparmelia cumberlandia - white lichen on rocks, and lots at 15:04. 10:24 Salvia mellifera (black sage) at left. 13:03 Eriogonum fasciculatum (CA buckwheat) - at center.

I spend all day polishing rocks and here I am staying up late watching videos about rocks and wishing I had some of those too. I have a 🪨 problem. 😂

Very cool!! You’re in the hillsides and the “neck of the woods” where I grew up!! I climbed and hiked the area surrounding Hemet and surrounding areas! Now I’m one of the few people living in Inyo County! I see you’ve done a couple videos up here and on to Mono County. A person with your interests could explore every day up here and never run out of amazing findings!!

Excellent lesson, Sir

That site brought back some memories. Paraglider pilots use that hill just up from where you parked your Jeep as a launch site we call Winchester Bowl. There is somewhat of a weed clearing about halfway up the hill where we would launch and fly for hours, then land down by your Jeep. I do remember finding shorl on that hill, and there were also largish books of mica. That last outcrop you dug around in looked familiar! There is also shorl over in the San Gorgonio Pass near Cabazon, but it is now hard to find specimens. I found a couple of pieces last year, but unless heavy rains wash away the surface, it hides from sight!

As a botanist, people are always humored when I casually use the word "botanize". But it's a common and long-used word. Didn't know the geologists did the same grammatically!

Had to come watch again, to share copy with a young friend interested in rocks. You are such a fun teacher, Todd. After living in Coachella Valley for 23 years, it is fascinating to finally learn about the terranes I traveled through so often. Many thanks for your videos.

The king has returned! Great vid, we've been missing you. Your excitement for geology is contagious

I like to think of SoCal as an area of crustal thinning, with magma oozing up through cracks in the crust. If you look at Panamint valley which is a long thin crack, you can see black mounds of basalt all along the length.

Wow! Great presentation. Only about 15 miles from my house. I'm going to go check that out very soon. Thank you.

What a fantastic episode! I wish I was bit younger so that I could explore more easily. This complex is just a short drive from where I live and I'm looking forward to learning more about the geology of S. California. I've always wanted to learn more about identifying Gabbro. Thank you for taking time from your very busy schedule to bring us along with you on your explorations.

I’ve just stumbled across your channel today. I’ve been spending a lot of time up at Mill Creek /Forest Falls and the rock there is fascinating. Here’s a hint that a video on that area would be much appreciated! 🪨

I love your enthusiasm for the geology of Southern California. Thanks for doing this.

I've lived in the IE and have often wondered about the Mountain/Hill ranges around, and their faultlines. The Hills along the 60 freeway (The Jurupa Hills), and the rock lines in them, I've always found interesting.

That gabro looks a heck of a lot like a granite.

Thanks for the geology lesson(finally lol)in an area of SoCal I have been driving through or around for 60 years.

I grew up hiking these hills and still live in the area. You gave the best explanation I have heard on the composition of minerals.

Excellent work

Cool! I truly appreciate your enthusiasm and Jeff Corwinesque presentation style. We travel a lot, and I buy Roadside Geology books to read and narrate the geology we drive through. Found your channel and diggin’ it big time! Thanks again!

I’m still requesting you to do Teneja Falls. The falls have a great diverse rock formations.
