About this map

Mining and rail infrastructure define this portion of the Plumas National Forest in the late 20th century. The settlement of Crescent Mills sits at the edge of Indian Valley, serving as a central point between high mountain ridges and the deep canyons of the East Fork Feather River. The industrial history of the region is evident in the numerous legacy sites, including the Arcadia Mine, Standart Mine, and the Monitor Mine. Evidence of earlier habitation remains at Round Valley, now overshadowed by the Round Valley Reservoir.

The complex engineering required for transport through this terrain is most visible in the Western Pacific Railroad alignment. South of Indian Falls, the tracks navigate a series of tunnels, from Tunnel No 26 through Tunnel No 33, as they follow the winding course of Spanish Creek toward the rail junction at Keddie. This network provided essential access to the timber and mineral resources of the Mount Hough Ridge area.
