About this map

Harrison Mine and Royal Mine anchor the northern reaches of this Napa County landscape, marking the historic mining activity that shaped this part of the California Inner Coast Range. The settlement of Knoxville sits at the junction of the Berryessa Knoxville Road, surrounded by the rugged contours of Adams Ridge and the Blue Ridge. This 1958 survey, updated with late 20th-century details in purple, documents significant industrial transformations, most notably the sprawling footprint of the McLaughlin Mine and the creation of the Davis Creek Reservoir.

The terrain is defined by dramatic ridgelines and secluded valleys like Cedar Valley and the evocatively named Mysterious Valley. The map records an infrastructure of remote utility, featuring a Landing Strip, Pumping Sta, and various water tanks. From the descent of Eticuera Creek to the secluded Lone Pine Thicket, the map captures a pocket of California where mercury and gold mining legacies meet modern water management and large-scale extraction operations.
