About this map

Tahoe National Forest encompasses the deep canyons and high ridges of this Placer County landscape, defined by the drainage of the North Fork American River. The terrain is marked by a legacy of subsurface exploration, with numerous portals such as the Golden Fleece Tunnel, Union Tunnel, and Macedon Tunnel cut into the steep slopes. High points like Duncan Peak and Sugar Pine Point are capped with lookouts, serving as critical vantage points for forest management.

Evidence of historical water management and industrial activity is visible at the American Hill Mine Reservoir and various mining sites including the Beauty Mine and Savage Workings. The network of trails and primitive roads, such as the Mumford Bar Trail and Mears 4WD Road, follows the natural contours, connecting isolated locations like Secret House and the high-elevation basin at Robinsons Flat.
