The rugged boundary between Merced, Santa Clara, and San Benito counties is defined by the sharp elevations of the Diablo Range in this 1960s-era topographic study. Mariposa Peak and Cathedral Peak tower over a landscape marked by legacy mining operations, including the Mariposa Mine, Ambrose Mine, and Stayton Mine. These sites reflect the region's mineral history, while the sprawling Quien Sabe Valley and the Santa Ana y Quien Sabe land grant area emphasize the long-standing ranching traditions of the California interior.
