About this map

Boise National Forest dominates this mountain landscape in central Valley County, characterized by a complex network of high ridges and alpine drainages. The North Fork Range forms a spine through the territory, punctuated by landmarks like Oro Mtn and the strategically placed Railroad Pass. The hydrography is defined by the Middle Fork Payette River and its numerous tributaries, including Tyndall Creek and Clear Creek, which carve deep valleys between the summits.

Transportation through this high-elevation terrain relies on a system of forest roads and trails, such as the Little Creek Cutoff and the Eureka Point Trail. High meadows and flats, including Stony Meadow, Gold Fork Meadow, and Porcupine Flat, provide rare level openings in the otherwise steep topography. These features, along with names like Lost Basin and Robb Springs, suggest a history tied to seasonal grazing and remote mountain exploration.
