1966 Map of Jumbo Mountain

USGS Topo · Published 1987

About this map

The Continental Divide serves as the high-altitude spine of this 1966 survey, marking the jagged boundary between Lemhi Co, Idaho, and Beaverhead Co, Montana. This high-country landscape within the Beaverhead National Forest and Salmon National Forest is defined by a network of drainage basins and peaks, including the prominent Jumbo Mountain and Squaw Mtn. Human presence is largely limited to traditional transit and light industrial activity, evidenced by a series of Pack Trails and a Jeep Trail that navigate the steep contours.
