About this map

The industrial and ranching legacy of the Sierra Nevada foothills is clearly visible in this survey, where the Stanislaus River carves a deep canyon between Gopher Ridge and Table Mountain. Centered on the copper mining hub of Copperopolis, the map illustrates a landscape transitioning from the frantic mineral extraction of the 19th century to early 20th-century infrastructure developments. Evidence of the region's mining heritage is found at the Wilbur-Womble Mine and Napoleon Mine, while the growing need for water management and transit is marked by Goodwin Dam and the winding Sierra Ry of California.

To the south, the historic crossing at Knights Ferry serves as a focal point for local transport, connected to outlying agricultural outposts like the Curtin Ranch and Rushing Ranch. The inclusion of the Rancheria Del Rio Estanislao land grant boundary and isolated educational sites like Orange Blossom School provides essential context for genealogists tracing family settlements across the Calaveras and Stanislaus county lines.
