2013 Map of Oro Mountain

About this map

Oro Mtn and the high ridges of the North Fork Range dominate this section of the Boise National Forest in central Idaho. The landscape is defined by its dramatic elevation changes, rising from the Middle Fork Payette River toward prominent landmarks like Railroad Pass and Clear Creek Summit. Transportation through this steep terrain is concentrated along a few key corridors, including Warm Lake Rd and the Nat For Dev Rd 413, which provide access to high-country basins such as Lost Basin and Porcupine Flat. Drainage patterns are intricate, with Johnson Cr, Alpine Cr, and Curtis Cr carving deep valleys through the timbered slopes. The presence of Stony Meadow and Curtis Lake offers a look at the few relatively level pockets within this otherwise vertical environment, where early forest service infrastructure and recreational access began to shape the modern use of the wilderness.
