About this map

Boca Reservoir and its massive Boca Dam dominate this mid-century landscape on the California-Nevada border. This area, managed by both the Tahoe National Forest and Toiyabe National Forest, shows a sophisticated water management and power generation infrastructure, including the Boca Powerhouse and a Gaging Station downstream. The Southern Pacific railroad follows the winding course of the Truckee River, connecting small industrial and transit points like Floriston, Hinton, and Iceland.

High-elevation landmarks such as Granite Peak, Ladybug Peak, and Verdi Peak—the latter featuring a Verdi Peak Airway Beacon—overlook the river canyons. Local geography is marked by historic naming conventions like Worn Mill Canyon and Stampede Valley. This survey captures the region's mid-century identity as a corridor for transport and energy production, set against the backdrop of the high Sierra and the Great Basin transition.
