1966 Map of Lost Trail Pass

About this map

The Continental Divide winds through this high-altitude junction of the Northern Rockies, serving as the dramatic boundary between Bitterroot National Forest, Salmon National Forest, and Beaverhead National Forest. This mapping, updated through the early 1990s, documents a landscape shaped by both natural drainage and human passage at the state line between Montana and Idaho. Key mountain crossings like Lost Trail Pass, Chief Joseph Pass, and Gibbons Pass are the focal points of the terrain, connected by the winding path of Highway 93. Signs of mid-century infrastructure and forest management are evident at the Hogans Guard Sta and the Lookout Tower atop Saddle Mtn. The map also captures local recreational and industrial features, including a Sports Area, a Roadside Park, and a Gravel Pit, alongside the headwaters of the North Fork Salmon River and Camp Creek.
