1951 Map of Cordelia

USGS Topo · Published 1956

About this map

Sulphur Springs Mountain and the surrounding canyons define the landscape of the Napa and Solano county border in the early 1950s. The region is marked by a mix of specialized industrial operations and emerging residential developments. Mining history is preserved at the St John Mine and several other unlabeled shafts, while the southern reach shows the footprint of the Permanente Foundation Hospital Area and the County Fairgrounds.
