About this map

Gold mining operations and high-elevation settlements define this section of the Sierra Nevada, situated at the boundary of Plumas National Forest and Tahoe National Forest. The map documents a landscape heavily influenced by the hydraulic and hard-rock mining era, featuring notable sites such as Poker Flat and the Potosi (Site). Steep drainages like Canyon Creek and Slate Creek separate prominent peaks, including Mt Fillmore and Saddleback Mtn, while a network of mines like the California Mine and Bunker Hill Mine are scattered across the slopes.

The inclusion of remote camps like Skyhigh and the rugged Craycroft Ridge provides a look at the mid-20th-century state of this backcountry, where industrial traces like the Wideawake Mine and Nestler Mine persist along the creek beds. This survey, based on 1946 aerial photography and 1951 field checks, offers a precise record of the road and trail network connecting the Plumas and Sierra county lines before later wilderness designations.
