2011 Map of Oro Mountain

About this map

Oro Mountain and the surrounding high country of Valley County define this landscape, where the headwaters of the Middle Fork Payette River gather before moving south. The 2011 survey documents a complex network of forest access routes, including Nat For Dev Rd 409 and Warm Lake Rd, which navigate the steep divide between major watersheds. High-altitude crossings like Railroad Pass and Big Creek Summit indicate the traditional passage points used to traverse the ridges between drainage basins. Deep basins and meadows, such as Lost Basin, Stony Meadow, and Porcupine Flat, break up the timbered slopes, while Curtis Lake provides a notable landmark in the central interior. This map is a record of the modern hydrological and transportation framework in a region characterized by numerous named tributaries, including Horsethief Creek, Johnson Creek, and Clear Creek.
