About this map

The Yuba River carves through a landscape of heavy hydraulic and dredge mining in this late 1940s survey. The river corridor is flanked by massive deposits and complex water systems, including the Cordua Canal and Stahl Ditch. The town of Hammonton sits at the center of this industrial geography, while Marigold appears nearby along the dredged banks. To the north, the foothills hold the Dannebroge Mine and Pennsylvania Mine, remnants of the region's gold mining heritage.

Southern portions of the map are dominated by the Camp Beale Military Reservation, showing the transition from agricultural land to defense infrastructure during the mid-century. Educational and social hubs are represented by the Browns Valley Sch and Brophy Sch, while local family legacies are preserved in names like the Sid Smith Ranch. The map also captures several irrigation and transport features like Daguerre Point, which managed the river's flow and sediment.
