1955 Map of Mt. Sizer

About this map

Henry Willard Coe State Park occupies much of this central California landscape, characterized by complex ridgelines and creek drainages in the Diablo Range. The map details the transition from the high ridges of Pine Ridge and Middle Ridge down toward the Coyote Lake reservoir. Historic ranching activity is evident through named sites like Los Huecos Ranch, Oak Flat Ranch, and Coe Ranch, while the presence of Madrone Soda Sprs and several distinct springs indicates the hydrological character of the canyon floors. The southwestern corner shows a shift toward more organized transport, where the pipeline and roads like Hill Road and San Pedro Ave emerge from the foothills. Numerous jeep trails and horse trails wind through Soda Springs Canyon and over Schoolhouse Ridge, illustrating the area's legacy as a site for both hard-scrabble ranching and wilderness recreation.
