About this map

Lemhi Pass marks the high-altitude boundary between Idaho and Montana, bisecting the Salmon National Forest and Beaverhead National Forest along the Continental Divide. This 1965 survey, updated through 1984, documents a landscape shaped by early Western migration and natural resource extraction. The northern portion of the map features the Sacajawea Memorial Camp, a significant commemorative site at the divide.
