About this map

Mustang Peak stands as the central landmark for this section of the Diablo Range during the mid-1950s, marking the rugged boundary between Stanislaus and Santa Clara Counties. The landscape is defined by a dense network of drainages and prominent ridges, where water management is crucial for the few established properties like the Gill Ranch. Numerous small catchments and reservoirs, including Bullhead Reservoir and Oak Springs Reservoir, are scattered throughout the canyons to support ranching operations in this arid terrain.

Transportation through the hills is limited to primitive routes, often following the winding paths of Orestimba Creek or Quinto Creek. Notable landmarks such as the Rooster Comb and The Narrows indicate the difficult passage through the northern canyons. To the south, Mustang Flat and Paradise Flat provide rare stretches of level ground amidst the steep slopes of Pine Springs Hill and Hammer Hill.
