2021 Map of Santa Rita Peak

About this map

Santa Rita Peak and the high ridges of the Diablo Range define this high-altitude landscape along the border of Fresno and San Benito counties. The terrain is characterized by complex drainage systems and isolated water sources, including Spanish Lake and numerous named springs such as Agua Buena Spring and Twentyfive Spring. The map documents a network of primitive roads and trails that traverse the steep topography, including Mexican Lake Rd and Derrick Rd, reflecting a region primarily used for ranching, resource management, or backcountry access. Significant geological formations like Joaquin Ridge, Wright Mtn, and the Three Sisters peaks stand alongside deep incisions like Diaz Canyon and Lewis Canyon. The presence of Adobe Flat suggests a rare break in the vertical relief, providing a glimpse into the physical geography of this segment of California's interior coast range.
