1956 Map of Priest Valley

About this map

Priest Valley anchors this mid-century survey of the Diablos Range interior, where the high-altitude settlement pattern reflects a reliance on protected valleys and seasonal water sources. The landscape is defined by the convergence of several major drainages, including Peachtree Valley and Indian Valley, which cut through the steep elevations of Mustang Ridge. Social and civic life in this remote cattle-ranching and farming corridor is evidenced by isolated institutional sites such as the San Lorenzo School and Slack Canyon School.
