About this map

The Tahoe National Forest dominates this landscape in Placer County, where the topography is defined by the deep incisions of the North Fork American River and its various tributaries. This 2015 survey reveals the complex water-management infrastructure characteristic of California's gold country, including the China Wall Iowa Hill Ditch and the Breeze and Wheeler Ditch. These historical water systems once fueled hydraulic mining and irrigation throughout the region.

Settlement is sparse, concentrated at Westville, Forebay, and Rawhide, while the subsurface history is marked by features like the Osborne Tunnel and Clara Tunnel. The map documents the high-elevation terrain of the Forest Hill Divide and Sawtooth Ridge, providing a clear record of the access roads like Foresthill Rd and Elliot Ranch Rd that traverse these ridges. From the Drum Forebay in the northwest to the East Branch El Dorado Canyon, the map illustrates a landscape shaped by both natural drainage and industrial persistence.
