About this map

The mining landscape of Copperopolis is the central focus of this survey, illustrating a region defined by its mid-century extraction history and rugged topography. Numerous shafts and mining operations are scattered across the terrain, including the Keystone Mine near the Copperopolis Reservoir and the Empire Mine further south. These operations, alongside sites like the Skyrocket Mine and Napoleon Mine, highlight the extensive prospecting that shaped the local economy and settlement patterns within the Copperopolis Ridge.

Beyond the central townsite, the landscape transitions into a series of prominent peaks and drainages, such as Boucher Mtn and Shirley Mountain. The southern portion of the map identifies the Calaveras Co Stanislaus Co line, crossing through areas like Rancheria and Del Rio Estanislao. Waterways like Littlejohns Creek and McCarty Creek carve through the ridges, while Base Line Road provides a primary transit link across the foothills.
