Don Edwards Preserve
4 bedrock mortars, possible cupules
Elevation 103 ft.

Another one of Jeff’s amazing finds.

Nearly all the bedrock mortars we’ve encountered in the Bay Area occur on sandstone. These are the only ones we’ve seen in metamorphic chert.


A closer look. Note the paired, shallow mortars. Such arrangements are rare. The only others we’ve seen are on Deer Island and out in Volvon territory.
