1956 Map of Copper Mtn.

About this map

Naval Bombing Range occupies a significant portion of this landscape, marking a period of mid-century military utility in the hills of Stanislaus County. The terrain is defined by a complex network of drainages including Del Puerto Creek and Adobe Creek, which carve through deep canyons like Hospital Canyon and Garden Canyon. This area shows a transition from resource extraction to recreation, with evidence of mining history at the Adobe Mine and various prospects set against the establishment of Frank Raines Park. High points like Copper Mtn and Gram look down upon isolated agricultural sites such as Oak Flats Ranch and high flats like Ballard Flat. The map also details numerous water sources essential for cattle and backcountry operations, from Fellows Spr to the Salt Grass Springs, connected by a web of primitive roads and 4WD tracks.
