About this map

The Mohawk Valley and its surrounding Sierra Nevada heights are documented here in the early 1980s, centered on the settlement of Clio. This area is a significant meeting point of geography and industry, where the Western Pacific RR follows the Middle Fork Feather River through a landscape heavily defined by early mining operations and timber lands. The transition from the Plumas National Forest to the Tahoe National Forest is marked by high-altitude features like Haskell Peak and Chapman Saddle.

Prospecting history is visible throughout the slopes, with several named operations including the Woodchuck Mine, Hayden Mine, and Locke Mine. Residential pockets like Haskell Creek Homesites and Carvin Creek Homesites appear alongside the older Mohawk Valley Ranch, illustrating the shift toward seasonal and recreational use of the land. The map also traces an intricate drainage network of creeks and meadows, such as Boulder Creek Meadow and Church Meadows, which long supported the local ranching and corral infrastructure.
