About this map

Explorer Peak and Brown Duck Mountain dominate this high-elevation wilderness within the Wasatch National Forest and Ashley National Forest. The landscape is defined by its glacial hydrology, featuring dozens of named alpine lakes and basins connected by a web of Pack Trails. Notable clusters include the Jack and Jill Lakes, the Rock Lakes at the headwaters of Rock Creek, and the chain of Upper Ottoson Lake and Lower Ottoson Lake within Ottoson Basin.

A distinct historic line, the Indian Treaty Boundary (Indefinite), cuts across the northern terrain, marking an era of shifting land use and tribal jurisdiction. From Dead Horse Pass to the sweeping Squaw Basin, the topography highlights the complex drainage patterns of the High Uintas, where numerous small creeks like Fall Creek descend from high passes into deep glacial valleys. This 1967 survey provides a precise record of these remote watersheds before modern environmental changes altered high-country snow and water levels.
