1955 Map of Emigrant Gap

USGS Topo · Published 1957

About this map

Graniteville and the surrounding Sierra Nevada foothills define this mid-century topographic portrait of a landscape shaped by mining and hydraulic engineering. The map reveals a complex infrastructure of water management, featuring the South Yuba Canal, Boardman Canal, and numerous tunnels like the Clear Creek Tunnel and Rucker Tunnel. These systems served both the power needs of the Rim Powerhouse and the extensive gold mining operations found throughout the region, such as the Gaston Mine and the Zeibright Mine.
