Shanti Ashrama and several historic ranching outposts define this high-altitude landscape in the Diablo Range. The map illustrates a network of seasonal watercourses and steep topography, centered on the San Antonio Valley and Upper San Antonio Valley. These high valleys have long supported isolated ranching operations, visible here through sites like Gerber Ranch, Capell Ranch, and Wiesendanger Ranch.
