Time to share my geologic map of Oakland, adapted from USGS Miscellaneous Field Studies Map MF-2342. That map covers a much larger area, but I’ve cropped it to Oakland and faded out the neighboring cities. You’ll note the slash of the Hayward fault. Also note how much of the bay shore is fill. Click the photo to access the 2400×2400 version.
I know you’ll enjoy staring at this. Feel free to copy the file to your own machine and view it at your leisure.
Happy holidays! By the way, I have a challenging Christmas geo-quiz up on About.com today; answers tomorrow in a separate post, so as not to spoil the experience for latecomers.

There are landslides all over the hills, most of which are not mapped. The best thing I can think of for you is to do a Google search, both web and images, on “oakland maps landslides.” There are several promising links.

love your site! I was looking for information on the landslides from the 60’s and 70’s in Oakland, and havent found much. I am interested in an area just below the Mormon Temple, the road below it is Jordan. At the very end, there was a huge landslide, Ive wandered around it and am interested in learning about it. please contact me if you can fill me in.

thanks for posting this – its hard to find high resolution geologic maps.
