2013 Map of Shewag Lake

About this map

The Continental Divide serves as the high-altitude spine of this map, marking the jagged boundary between Idaho and Montana. This high-country region is divided between the Salmon National Forest and the Beaverhead National Forest, characterized by steep drainages and prominent summits like Eagle Mtn and Pyramid Peak. The hydrology is particularly complex here, with headwater streams such as Shewag Cr and the N Fork Sheep Cr radiating from the peaks. The namesake Shewag Lake sits tucked into a glacial cirque below N Mtn, providing a focal point for this wilderness landscape. Human presence is minimal, primarily represented by the Fourth of July Creek Rd and a network of drainages like Cassel Gulch and Elkhorn Gulch that hint at the area's prospecting and grazing history.
