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.

Genealogists and local historians can find traces of earlier settlement patterns through labels for the Central Ferry (Site), the O'Byrnes School (Site), and the Rancheria Del Rio Estanislao Boundary Line. The terrain is characterized by the prominent Gopher Ridge and Table Mountain, which dictate the paths of ranch roads like Milton Road and Angels Road connecting scattered family holdings such as the Wagner Ranch and Rushing Ranch.
