2020 Map of Shewag Lake
USGS Topo · Published 2020About this map
The Continental Divide forms a high-altitude spine across this landscape, marking the boundary between Lemhi County and Beaverhead County. This 2020 survey documents the intersection of the Salmon National Forest and Beaverhead National Forest, where the Continental Divide National Scenic Trail winds through peaks like Pyramid Peak and Sheep Mtn. The hydrology of the region is defined by drainages such as Shewag Cr, leading to the namesake Shewag Lake, and Carmen Creek further south. Modern access is limited to high-clearance routes including the Fourth of July Creek Rd and the specifically noted Mine Rd off Stein Mt Rd, indicating the historical significance of mineral exploration in these remote mountains.
