About this map

The Selway-Bitterroot Wilderness straddles the high ridgeline between Idaho and Montana, forming a high-altitude landscape of drainage basins and glacial lakes. This mid-1960s survey documents the complex boundary where the Nezperce National Forest and Bitterroot National Forest meet. The terrain is characterized by steep peaks such as Vance Mountain and deep water features like Tin Cup Lake and the Triple Lakes.

Surface water flows through a network of creeks including White Cap Creek, Capitan Creek, and Canyon Creek, many of which follow the deep valleys carved between the ridges. The presence of several Pack Trails indicates the primary method of traversal through this protected wilderness area, which was formally designated just as this topography was being field-checked in 1964. The map provides a precise record of the divide between Idaho County and Ravalli County.
