About this map

Sawtooth National Forest dominates this high-altitude landscape in Oneida County, where the Sublett Range creates a complex system of drainage and relief known as the Sublett Troughs. The area is defined by its water sources, which serve as vital landmarks for navigation and land use in this arid environment. Significant features include Eyrie Peak and the critical Summit Springs Pass, which provides passage between deep incisions like Eyrie Canyon and Heydlauff Canyon.

Hydrological patterns are clearly marked by the convergence of the North Fork Sublett Creek and South Fork Sublett Creek, leading toward the Pine Cr Reservoir. The map reveals a network of historical transit corridors and trails, such as the Lake Fork Loop Trl and Hartley Canyon Rd, which trace the natural contours of the canyons. Smaller, named water features like Kossman Seep and Yellow Jacket Spring highlight the specific local knowledge required to navigate this portion of the Idaho backcountry.
