About this map

The Boca Reservoir and the Truckee River corridor dominate this mid-century topographic survey of the California-Nevada border. This area showcases the critical water and transport infrastructure supporting the Sierra Nevada region, anchored by the Boca Dam and the Southern Pacific railroad line. The settlement of Floriston sits along the river at the base of the Toiyabe National Forest, while the namesake settlement of Boca is positioned near the junction of the main river and the Little Truckee River.

High-altitude landmarks such as Verdi Peak, which includes a Lookout and an Airway Beacon, reflect the era's reliance on terrestrial navigation and fire spotting. The complex terrain is carved by numerous drainages like Mystic Canyon and Worn Mill Canyon, providing a detailed look at the landscape before modern development further altered the valley floors. Industrial footprints are visible through features like a Powerhouse, a Gaging Sta, and a long flume tracing the river's edge south of Acid Flat.
