About this map

The Little Truckee River and Truckee River define this high-altitude landscape on the California-Nevada border. This mid-century survey captures the region as water management infrastructure began to reshape the terrain, with the Boca Reservoir already established and the future shoreline of the Stampede Reservoir indicated by 1969 revisions. The Southern Pacific River railroad follows the winding river canyon, connecting small settlements and rail-side points like Floriston, Mystic, and Iceland.

Industrial and utility markers include a Powerhouse and Valvehouse near Boca, while the surrounding geography is dominated by the Tahoe National Forest and Toiyabe National Forest. The map also details several high-country flats and peaks, including Cox-Delaney Flat and Granite Peak, providing a clear look at the transit and water corridors of the Sierra Nevada before modern interstate expansion fully altered the valley floors.
