A couple of places that I found interesting - Earthquake trail near Point Reyes and Sibley Volcanic Regional Preserve near Oakland.

The Los Trancos Open Space Preserve in the hills above Palo Alto has a San Andreas Fault Trail along a segment of the San Andreas which broke in 1906. Across the road in the Monte Bello preserve, there is a great example of a sag pond along the Canyon Trail (a fire road) about 1/2 mile down. You might also check out The Pinnacles National Monument, it's a ways south of the Bay but a spectacular example of a formation that moved with the fault (the other half is Devils Punchbowl on the back side of the San Gabriel Mtns).

Great channel. Glad I discovered it. NGL lived in CA my entire life and never knew Sutter Buttes were a volcano. Just wow!

There are lots of good suggestions here. I suggest looking into the excavation of the most recent bore at the Caldicott Tunnel (Hwy 24 Berkeley to Orinda). The excavation uncovered lots of cool fossils, and I think it would make a great short.

The cal memorial stadium is built directly on the Hayward fault so that could be a cool thing to look at in the video for a small segment.

I second Castle Rock State Park and will also mention that Wilder Ranch State Park was home to an early Bitumen/asphalt quarry in the late 1890's, which was used to pave roads in San Francisco, Seattle, and even Salt Lake City, but the quarry site isn't accessible to the public so I'm not sure it'd be visit worthy for that alone (though it is beautiful!)

Classic Monterey Formation outcrops eastbound on Claremont Ave (east of the Claremont Resort) before intersection with Fish Ranch Rd. Get after it!

In the East Bay, Sunol Regional Wilderness has a spot called "Little Yosemite" where these really neat blue rocks (dunno what kind they are) with quartz inclusions all through 'em. There's also a green variety of I think the same type of rock, but IIRC the blue ones are only from the Sunol area. The Altamont pass hills are probably pretty interesting geologically. They're very "rolly" lol. Brushy Peak in that area might be something worth looking into. Not far away from there is a neat place called Morgan Territory--up there are mines, and bluffs, and cool formations to check out.. 👍

Gilroy Hot Springs is a little known spot with some human history. Also there are places where fault displacement is visible at the surface like a fence at Point Reyes National Seashore and also some sidewalks in the town of Hollister.

I guess if you wanted to you could visit either Mussel Rock or Pt Reyes/Bodega Bay, inasmuch as they are also along the trace of the San Andreas Fault. Interesting part about Pt Reyes is that on the west side of the fault, all the rock and flora there got their start in the southern Sierra Nevada, and now finds itself 300 miles north of where it started after all the movement along the San Andreas Fault. That has always intrigued me. Mussell Rock is just where the San Andreas heads off under the Pacific from the SF Peninsula.

Corona Heights Park in San Francisco has a fascinating slick-walled mini fault in its lower reaches on the northeast side. Also, the Ice Age hydrology of the Bay is surprising and worth discussing—the path of the Sacramento-San Joaquin River between Angel Island and Tiburon, its passage through the Golden Gate, now submerged and hence tide-scoured to a depth of 300+ feet, and the large fan-shaped delta that spread out to the Farallones. Plus: Franciscan chert! Graywacke! Serpentinite! Pillow lava! All the legacy of an extinct subduction zone.

Alum Rock Park in San Jose. Hot Springs, Sulfur Springs not to mention a neighborhood of homes removed but their plants still there. Strange 😲. follow the fault

Love your stuff. Why are the Santa Cruz Mtns there? My East bay friend liked your Mt. Diablo video... He's lived there his whole life. - Ed in reno

Very much self-serving because it's in my backyard, but: the volcanic zone around the Mayacamas. Fore-arc volcanism is interesting, right?!

Hi, all! Thank you so much for tuning into my channel and watching my videos, I appreciate it so much :)
I'm currently working on a new video- "Geology of San Francisco & The Bay Area", similar to my episodes on Los Angeles and Las Vegas/Southern Nevada (part of the Geology of US Cities miniseries).
As such, I was hoping for some recommendations! Do any San Francisco Bay Area locals or Bay Area experts have any suggestions on cool geology spots around the Bay Area that you would like me to visit to discuss for my upcoming video?
For now, I'm definitely going to make my way to the Hayward Fault, San Andreas Lake/Fault, Salinian Block, and Marin Headlands, but I'm open to and in need of some more places to visit for this project!
Thanks, y'all!
