The Diablo Range serves as the backbone for this remote section of the California Coast Ranges, where the borders of Stanislaus, Santa Clara, Alameda, and San Joaquin counties converge. This high-country landscape is defined by its deep drainages and prominent peaks, including Mt Boardman and Mt Mocho. The interior of the range is accessible primarily via winding routes such as Mines Rd and Del Puerto Canyon Rd, which follow the natural contours of the land through steep corridors like Del Puerto Canyon.
