Upper Suisun Valley
Bedrock Mortar Sites
(Solano County)

Upper Suisun Valley was once the site of the Southern Patwin Village of Sonetro, which was on the east side of Suisun Creek, and just a little over 4 miles north of the Village of the Suisun (also called the village of YulYul - see the Rockville Hills sites). Sonetro was probably closely associated with YulYul, which was also probably much larger. Close to Sonetro are two bedrock mortar sites, which were probably food gathering camps for the main village. Both sites are on private property with no public access.
