Upper San Leandro Reservoir


Upper San Leandro Reservoir
8 bedrock mortars, 3-5 cupules. Site may be underwater.

This is a beautiful spot now because of the Upper San Leandro Reservoir, but it was probably nice in Jalquin times too. Back then these mortars were on a little hillside terrace above Kaiser Creek, a perennial watercourse. How many mortars here and how many sites altogether lie drowned in this reservoir and nearby Lake Chabot?

This site is in a restricted area. Secure permission before visiting it.

Bob clears mud from a mortar on a sandstone outcrop. Note the volcanolike mortar behind him.
