1954 Map of Copperopolis

USGS Topo · Published 1956

About this map

Copperopolis serves as a focal point for this mid-century survey of the foothills where Calaveras, Tuolumne, and Stanislaus Counties converge. The landscape is defined by the winding Stanislaus River and the industrial infrastructure of the Hetch Hetchy Aqueduct and Sierra Railroad. Historic mining activity is documented at the Napoleon Mine and Green Spring Mine, while the shifting local economy is visible in the presence of the Tulloch Reservoir and Goodwin Dam.
