ALA-60 at Crow Canyon Road and Castro Valley Boulevard


ALA-60
44 bedrock mortars and 182 cupules near the intersection of Crow Canyon Road and Castro Valley Boulevard.

The official trinomial for this site is CA-ALA-60. E. Breck Parkman, Senior State Archaeologist for California State Parks, suggests this may be one of the oldest acorn processing sites in the Bay Area. Cultural material excavated here has been dated back more than 8,000 years. The first inhabitants of this site were probably not Ohlone, let alone Yrgin. People may have lived here when salt water first intruded through the Golden Gate to begin the formation of San Francisco Bay.

This site is (sort of) fenced off, but if that doesn’t stop the homeless from camping here, should it stop you? Use your best judgment.

Jim and Heather check out the site.


Despite–or perhaps because of–ALA-60’s antiquity and significance to Bay Area prehistory, the site is neglected and overgrown with vegetation.
