That *is* interesting. Might be worth asking at some historical society.

Also interesting that the topography is so clear. It would be obvious to somebody looking at it today that those hills have faults involved - but maybe not at the time, before the 1933 quake, other than maybe for some oil drillers who worked in the area.

The area is, of course, all built-up now, though there is a significant flood control channel in the general area of the slough. Flood risk maps are not available online - must go to a city office to look at them - but I wouldn't be surprised at the slough area still having some flood risk during a 1% (100-year) storm.
