1956 Map of Copper Mtn

About this map

Naval Bombing Range dominates the southern landscape of this central California region, marking a significant military footprint amidst the canyons. This 1956 survey, updated with revisions in 1971, captures a rugged interior used for more than just training; the presence of Adobe Mine near Adobe Canyon and numerous prospects suggest a history of mineral exploration. The terrain is deeply incised by drainages like Del Puerto Creek and Salado Creek, where seasonal water sources such as Fellows Spr and Salt Grass Springs provided vital points for early settlers and ranchers. High points like Copper Mtn overlook a network of unimproved roads and jeep trails that connect isolated outposts like Oak Flats Ranch and Ballard Flat. This map preserves the mid-century character of the Stanislaus backcountry before modern developments altered these traditional ranching and mining landscapes.
