About this map

Plumas National Forest dominates this landscape where the Middle Fork Feather River and South Fork Feather River carve through high country. Mapping from 1948, later updated in the 1970s, captures a transitional period of resource management and local settlement. The terrain is marked by prominent family-named outposts such as Boehme Ranch and McIntosh Ranch, reflecting the enduring footprint of early homesteading in the Sierra Nevada.

Evidence of historical industry is scattered across the ridges, from the Browns Hill Mine near Camel Pk to the Sanborn Mine. The development of water infrastructure is visible at Grass Valley Res, while old transport corridors are represented by the route toward La Porte. This area's geography is defined by its deep canyons and high points like Lexington Hill, serving as a record of the shifting balance between natural preservation and mountain enterprise.
