Virtual field trip: Geology of San Francisco

Streetcar 2 Subduction is a collection of virtual geology field trips that take users to some of the world-class geological sites of the San Francisco Bay Area. Watch this and other videos in the collection for tours of Angel Island, Corona Heights, Glen Canyon Park, and more.
In this video, Callan Bentley gives an overview of the geology of San Francisco and the different types of rock found around the Bay area while getting a great view of the city from Corona Heights Park.

I have been slowly grasping the geology of the bay area, but it's extremely complicated.
Sometimes I think of it as the massive wreckage of a subduction zone that then got sliced and diced by transform faults lol ...

Dude, you are, forgive me for this, rocking my world right now. Not only did you do a segment on the Hayward fault in Fremont where I grew up that opened my eyes to the local geology I grew up with, but now you're in The City where I lived in The Haight in the 90's. I had no idea SF had swaths of serpentinite in its terrain. My exposure to this rock comes by way of Baja-BC, but SF is on the continental side, so I guess not all serpentinite originates in Mexico??? I guess the magnetic signature tells it all.
