About this map

Mount Diablo and the surrounding peaks of the northern Diablo Range dominate this mid-century survey of Contra Costa County. The map captures a significant period of suburban transition, where purple-tinted urban extensions from 1968 overlie the original 1953 topography. This development is most evident around Clayton, Galindo, and Cowell, as new campuses like Clayton Valley High School and Highlands School appear alongside older agricultural markers.

South of the residential growth, the landscape remains defined by its natural hydrology and early industrial history. Significant drainage systems such as Mt Diablo Creek and Mitchell Creek carve through the foothills, while the rugged southeastern corner preserves the memory of early mining efforts at the Nortonville site and the Mt Diablo Mine. From the high elevations of North Peak down to the Cowell Cemetery, the map provides a precise record of how the valley floor was reshaped as the Naval Reservation and Camp Stoneman lands met the expanding postwar suburban frontier.
