About this map

Copperopolis sits at the heart of this Sierra Nevada foothills survey, surrounded by a dense network of shafts and tunnels that defined the regional economy since the mid-19th century. The landscape is dominated by mining operations following the geological seams of Gopher Ridge, including the Empire Mine, Keystone Mine, and North Keystone Mine. This 1962 field check reveals a terrain etched by extraction, where family-named landmarks like McCarty Creek and Boucher Mtn neighbor specialized workings like the Skyrocket Mine and Wilbur Womble Mine.

Further south, the small settlement of Telegraph City and a nearby Cem provide important markers for local history and genealogy. The topography transitions from the industrial activity near town toward the southern reaches of the Rancho Del Rio Estanislao and the county boundary at Calaveras Co Stanislaus Co. This map captures the intersection of early California ranching and the intensive copper mining that once made this area a vital industrial hub.
