1897 Map of Downieville

About this map

The Middle Fork Feather River and its high Sierra tributaries define this landscape, which in the late 19th century was a center of intensive hard-rock and hydraulic mining. The region is marked by an extensive network of mining operations, including the noted Plumas Eureka and Empire Mine, alongside several camps and settlements that served the industry. Quincy sits at the edge of American Valley, while further south, the Sierra Turnpike winds through the hills toward Howland Flat and La Porte. The survey captures a moment when the rugged terrain was heavily worked for its mineral wealth, shown by the numerous mines like the Phoenix Mine and Keystone Mine dotting the ridges between the forks of the Yuba and Feather rivers. Faint trails and roads connect isolated outposts like the St. John Ranch and Spring Garden Ranch through the high passes of the Grizzly Mountains.
