1967 Map of Borah Peak

About this map

Borah Peak dominates this high-altitude landscape within the Challis National Forest, reaching an elevation of 12,662 feet. The 1967 survey documents the dramatic topography of the Pahsimeroi Mountains, where high mountain passes like Doublespring Pass and Horseheaven Pass provided critical transit points across the range. Water sources are meticulously noted in this arid environment, ranging from Mule Spring and Freighter Spring to a small Dam and Aqueduct located near Birch Springs and Cedar Creek. The drainage patterns are clearly defined by Willow Creek and Mahogany Creek, illustrating the complex watershed of the Lost River Range. This map serves as an essential record of the area's physical geography before the expansion of modern recreational infrastructure, preserving the names of remote canyons like Cayuse Canyon and local water management features used during the mid-20th century.
