1966 Map of Lost Trail Pass

USGS Topo · Published 1970

About this map

Lost Trail Pass and Chief Joseph Pass serve as the primary gateways across the Continental Divide, where the high-altitude borders of the Bitterroot National Forest, Beaverhead National Forest, and Salmon National Forest converge. This 1966 survey documents a mid-century landscape of recreation and forest management, featuring a Ski Tow and Sports Area near the pass, alongside the Roadside Park and the remote Hogans Guard Sta. The network of Pack Trails and Jeep Trails provides access to prominent heights like Saddle Mtn, which is topped by a Lookout Tower. Headwaters of the North Fork Salmon River and Joseph Creek illustrate the hydrographic importance of this mountain crest, while a single Prospect and Gravel Pit indicate localized industrial activity.
