About this map

The Middle Fork Feather River and the Western Pacific railroad corridor anchor this high-altitude landscape where Plumas and Sierra counties meet. Settlement patterns here reflect a mix of traditional ranching and burgeoning mid-century residential pockets, evidenced by the Mohawk Valley Ranch and newer developments like Haskell Creek Homesites and Carvin Creek Homesites. The rugged geography of the Mohawk Valley is defined by steep drainages like Sulphur Creek and Boulder Creek, which feed into the river system.

Resource extraction and surveillance are central themes, with several namesake workings including the Hayden Mine, Hayes Mine, and Woodchuck Mine scattered across the slopes. High-ground observation is represented by the Mills Pk Lookout, while the southern reaches of the map transition into the Tahoe National Forest, centering on the prominent Haskell Peak. This record captures a moment when timber, rail, and early mountain recreation infrastructure coexisted in the Northern Sierra.
