1956 Map of Copper Mtn

About this map

Naval Bombing Range operations define a significant portion of this Stanislaus County landscape, as mapped during the mid-1950s and updated in the early 1970s. The terrain is a complex network of canyons and gulches, where narrow seasonal waterways like Salado Creek and Adobe Creek drain the slopes of Copper Mtn. Resource extraction is evident at the Adobe Mine, while cattle ranching and recreational use appear at Oak Flats Ranch and Frank Raines Park. The nomenclature of the area reflects a rugged frontier history, with names such as Murderers Gulch, Blind Mans Gulch, and Salt Grass Canyon identifying the deep folds of the Diablo Range. Water management is critical in this environment, shown through numerous scattered Reservoir sites and natural sources like Salt Grass Springs and Fellows Spr. A limited network of jeep trails and unimproved roads provides the only access through this topography, illustrating the area's isolation prior to modern development.
