East Bay Wall Photographs

R. Swanson has kindly sent some photographs of the East Bay Walls described in SF#38. The photo on the left shows a rather complete section, 5-feet high, on Mission Peak, Fremont, California. N. Fink is shown measuring this wall. On the right, one of the walls leads to a "hill fort" at an elevation of 1,400 feet. Two other walls terminate at this rock pile. This wall has obviously experienced the ravages of time. It is said that these walls were in place when the Spanish arrived.
