1958 Map of Morgan Valley
USGS Topo · Published 1966About this map
Knoxville and its surrounding mineral wealth define this 1958 survey of the California Coast Ranges, where the mining industry left a permanent mark on the landscape. The map details a concentrated cluster of mercury and cinnabar operations, including the Manhattan Mine, Red Elephant Mine, Royal Mine, and Harrison Mine. These workings are situated near the intersection of Lake, Napa, and Yolo counties, a region where the Cache Creek canyon cuts through the Blue Ridge and Swanson Range.
