1955 Map of Emigrant Gap

USGS Topo · Published 1965

About this map

Southern Pacific rail lines and high-altitude mining operations define this mid-century look at the Sierra Nevada crest. The map documents a landscape transitioning from its 19th-century gold rush roots to a modern hydroelectric and transportation corridor. Former mining hubs like Graniteville and Omega appear alongside former community locations at Summit City and Baltimore Town. The industrial legacy is visible in the dense concentration of workings such as the Yellow Metal Mine, Nixon Mine, and Alpha Mine, as well as the hydraulic infrastructure of the Zion Hill Tunnel and Drum Forebay.
