The high alpine country of the Pioneer Mountains dominates this landscape within the Beaverhead National Forest. Anchored by the towering peaks of Tweedy Mountain and Torrey Mountain, the region is a complex network of glacial basins and high-altitude water bodies, including Glacier Lake, Torrey Lake, and Gorge Lakes. The topographic detail reveals a landscape shaped by water and rock, where steep drainages like Birch Creek and Thief Creek carve through the mountain range.
