1955 Map of Blue Canyon

About this map

Tahoe National Forest terrain dominates this mid-century survey, where the heavy infrastructure of the Sierra Nevada is clearly mapped. The Southern Pacific railroad and early highways trace the ridge through Emigrant Gap, passing the Emigrant Gap Historical Marker and specialized installations like the Blue Canyon Weather Station and Airway Beacon. The map documents a complex water management system essential to the region's industry and power, featuring Spaulding Lake, Fuller Lake, and the Drum Forebay. Evidence of the area's rich mining history is everywhere, from the Eagle Bird Mine and Arctic Mine in the north to the Zelbright Mine near Bear Valley. Small settlements and work camps, including Omega, Carpenter, and Blue Canyon, are clustered near the transportation and water corridors that define this landscape.
