Mustang Peak and the surrounding ridgelines of the Diablo Range define this high-elevation landscape along the border of Stanislaus and Santa Clara Counties. This terrain is characterized by a dense network of canyons and seasonal watercourses, including Garzas Cr, Quinto Cr, and the S Fork Orestimba Cr. The map reveals a land managed for water resources and trail access, marked by the Bullhead Reservoir and Oak Springs Reservoir. A complex system of footpaths and pack trails, such as the Rooster Comb Trl, Mustang Pond Trl, and Dutcher Trl, provides the primary means of navigating the steep topography between Mustang Flat and the high points of Hamner Hill and Black Hill. This 2018 survey provides an essential view of the watershed and recreational geography of the inner Coast Ranges.
