As part of the 1993 field school from San Francisco State University, I directed excavations at a newly identified site in the Sunol Valley, Alameda County. A goal of the project included investigating whether the site was a historic rancheria associated with the Sunol adobe complex, which was once situated nearby. The site was mapped, and a surface survey was conducted. Mechanical testing was carried out, and five 1 x 2 meters units were excavated. A phosphate study was completed, and a ground penetrating radar analysis was carried out. The project will be descirbed and preliminary results outlined.
