About this map

Copperopolis stands as the primary hub of this 1940s-era landscape, where the hardrock mining legacy of the Mother Lode is evident through numerous named workings. Industrial activity is concentrated at sites like the Wilbur Womble Mine, Napoleon Mine, and the Alto Mine, while the physical geography is dominated by the massive Table Mountain and the canyon of the Stanislaus River. The southern portion of the map reveals a sophisticated water management system, featuring the Tulloch Ditch, South Ditch, and the South Distributing Main to support the local agriculture and infrastructure.
