About this map

Mt Boardman and Mt Mocho anchor this high-elevation landscape within the Diablo Range, where the borders of Santa Clara, Stanislaus, Alameda, and San Joaquin counties converge. The terrain is defined by a dense network of steep drainages, including Hospital Canyon and Del Puerto Canyon, which have historically shaped travel through these remote highlands. Road access is limited to rugged corridors such as Mines Rd and San Antonio Valley Rd, reflecting the area's isolation and its primary use for ranching and resource extraction.

Water sources like Passionate Spring and Sulphur Springs Cr provide rare points of relief in a landscape dominated by named peaks and dry valleys. Significant landmarks such as Red Mtn and Blackbird Valley suggest a history of localized naming by early settlers and ranchers. This 2018 survey detail provides a clear view of the complex topography and sparse infrastructure that continues to define this section of the inner Coast Ranges.
