About this map

Mount Diablo State Park anchors this landscape, with its northern slopes reaching toward Mount Diablo and the State Game Refuge. The 1950s terrain transitions from the steep ridges of Black Hawk Ridge and Fossil Ridge down into the developing residential and agricultural pockets of the San Ramon Valley. Along the western edge, the Southern Pacific railroad corridor serves as the primary artery for the communities of Danville, San Ramon, and Diablo.

Insights into mid-century expansion are visible through 1968 updates, showing the growth of schools like Monte Vista High Sch and Athenian Sch. Historic land use is evident in the sprawling Black Hawk Ranch and named campgrounds such as Live Oak Camp and Rock City. From the Sherburne Hills to the winding Sycamore Road, the map documents the shift from ranching and rural life to suburban development at the foot of the peaks.
