1951 Map of Helena

USGS Topo · Published 1953

About this map

Helena and the Trinity River corridor anchor this mid-century look at one of California's most active gold mining districts. The 1951 field check reveals a landscape deeply marked by extraction, from the clustered claims along the river at Idaho Bar and Coopers Bar to hard-rock operations in the high country. Significant lode mining sites like the Enterprise Mine, Yellowstone Mine, and McClaron Mine are located throughout the Trinity National Forest, illustrating the remote nature of these industrial outposts.
