About this map

The Boise National Forest in Elmore County dominates this high-elevation terrain, defined by a complex network of drainages feeding into the Roaring River. This 2020 survey documents a landscape of dramatic verticality, from the peaks of Sheep Mountain in the west to the prominent spine of Trinity Ridge in the east. The southern portion of the quadrangle is punctuated by alpine water bodies, including Little Trinity Lake, Little Roaring River Lake, and the Twin Sisters Lakes, situated at the foot of the Trinity Mountains.

A network of forest service routes, including Deadman Creek and Roaring River roads, provides access to the backcountry, while the William Pogue National Recreation Trail offers a route through the central forest. The map reveals the precise hydrology of the region, tracing the E Fork Roaring River and Whiskey Jack Cr through deep canyons, providing an essential reference for understanding the modern recreational and conservation management of this Idaho wilderness.
