The Lochsa River carves a deep path through this mid-1960s landscape, serving as the central artery for a region defined by its protected wilderness status. This survey shows the boundary between the Clearwater National Forest and the Selway-Bitterroot Wilderness, highlighting a period when management and access infrastructure were actively developing. The Lochsa Work Center and a nearby Gaging Station indicate the administrative and scientific oversight of the river corridor.
