About this map

The Selway River carves a deep path through this portion of the northern Rockies, dividing a landscape dominated by high ridges and localized mountain flats. This 2017 survey documents the intersection of the Bitterroot National Forest and the Salmon National Forest, showing a wilderness character defined by steep elevation changes. Notable clearings and relatively level ground are found at Thompson Flat and Storm Creek Flat, which provide rare points of lower-relief terrain amidst the surrounding crests of Goat Ridge and Storm Ridge.

Drainage systems are intricate, with numerous tributaries such as Three Lakes Cr, Wilkerson Cr, and Surprise Cr feeding the central river valley. The map also delineates the high point at Wood Hump and follows the high-altitude route of Square Top-West Horse near the boundary between Idaho and Lemhi counties. This record is particularly valuable for its detail on water sources and terrain features in a region with very limited modern infrastructure.
