1969 Map of Mariposa Peak

About this map

Mariposa Peak stands at the center of this high-relief terrain in late 1960s California, where the borders of Santa Clara, Merced, and San Benito counties converge. The landscape is defined by its mining history and rugged cattle country, evidenced by the presence of the Ambrose Mine, Mariposa Mine, and Stayton Mine alongside established holdings like French Ranch and Pfeiffer Ranch. The map reveals a complex network of canyons and ridges, including Peckham Ridge and Twin Peaks, which transition into the drainage basins of Los Banos Creek North Fork and the Arroyo de las Viboras. In the northeast corner, the San Luis Reservoir State Recreation Area marks a significant water management and recreational feature, while several springs and gulches like Spicer Gulch highlight the hydrology of this semi-arid upland environment.
