Speakers of Bay Miwok dialects occupied most of the area of Contra Costa County not bordering San Francisco or San Pablo bays. The territory of one Bay Miwok tribe, the Jalquin, may have extended into Alameda county and touched San Francisco bay at the mouth of San Leandro Creek.

Volvon Village on Mallory Creek

Volvon Village on Mallory Creek 715 bedrock mortars and countless housepits spread over a half mile. Cupule rock.

It does not appear […]

The notch cut by Sycamore Creek through the Black Hills provides one of the few easy routes into Volvon territory, so this camp may have had […]
