I've become sloppy in thinking about these faults, but used to do a lot of seismics on them. I still have nightmares about the thrusts, "horse faults" and other strange stuff that we used to map with primitive 2d stuff and very old style computers from oil company lines. Did anybody ever figure out that double reflection from the sea floor? The faults are a mess (good technical term, eh?)showing all kinds of movement and deformation styles. I'm too lazy right now to go get my maps or the good old "Geology of California"

I was in SB area from '67 until '06. Oddly quiet area in some ways except for activity that I mentioned in earlier post, and the gases bubbling offshore. Yes...I do think that it was Ed Keller. He was the pro on local faults when I was there, and often had his classes go out to the Rincon area to map. The "beast" is a big antiformal structure south of Goleta, much loved for active gas production. I think that one oil company actually tented it. They used it as a selling point to keep tar off of the beach and help prevent oil slicks. (I never quite agreed with that!)

Take care.
