Mount Diablo and its surrounding peaks dominate the landscape of this Contra Costa County survey, which documents the rapid expansion of suburban infrastructure into the foothills during the late 1960s. Purple tinting highlights the growth of residential areas and schools like Clayton Valley High Sch and El Dorado Intermediate Sch near the traditional center of Clayton. This development contrasts with the industrial and mining heritage of the region, evidenced by several Quarries and the identified Nortonville (Site) to the east.
