1955 Map of Blue Canyon

USGS Topo · Published 1957

About this map

Southern Pacific tracks wind through the high Sierra Nevada terrain, tracing a vital transportation corridor through Emigrant Gap and Blue Canyon. This mid-century survey illustrates the complex water management and mining infrastructure of the Tahoe National Forest, featuring an intricate system of the South Yuba Canal, various flumes, and the Drum powerhouse system. The landscape is marked by the legacy of the gold rush, with several sites noted as inactive, such as the Gold Bug Mine and Eagle Bird Mine.
