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.
