1956 Map of Donkey Hills

About this map

The Pahsimeroi Valley serves as a wide high-altitude corridor between the high peaks of the Lemhi Range and the Donkey Hills in this mid-century survey of Idaho's interior. Human activity is centered on the floor of the valley and along the Pahsimeroi River, where remote settlements like Goldburg and its namesake Goldburg Sch supported a ranching economy. Family-named holdings such as Lone Pine Ranch, Swauger Ranch, and Summit Ranch indicate the scattered nature of land use in this period. Higher elevations are dominated by the Salmon National Forest and Challis National Forest, rising to prominent points like Big Creek Peak and Flatiron Mtn. A network of water sources, including Goldburg Creek and Summit Res, highlights the critical importance of water management in this arid high-mountain environment.
