The Lewis and Clark National Historic Trail threads across the northern ridges of this Idaho landscape, following the high ground of the Powell Ranger District. This 1990s survey shows a wilderness managed for both preservation and utility, where the Lochsa Recreational River carves a deep valley through the Clearwater National Forest. Transportation infrastructure is concentrated along the river corridor, including the Eagle Mtn Pack Bridge and the Idaho State Maintenance Yard.
