1997 Map of Shewag Lake

About this map

The Continental Divide forms the primary spine of this high-elevation wilderness, serving as the physical border between Lemhi County, Idaho, and Beaverhead County, Montana. This 1990s revision details the shared boundaries of the Salmon National Forest and Beaverhead National Forest, highlighting a landscape shaped by glacial topography and remote drainage systems. Landmarks such as Pyramid Peak and N Mountain overlook the alpine waters of Shewag Lake, which feeds into the cascading Shewag Creek. The map documents a network of primitive access routes, including the Wisdom North Fork Trail and the Ranger Trail, which navigate the steep headwaters of Sheep Creek and Prunari Creek. This survey records the late-twentieth-century state of these protected lands before modern forest management and fire regimes altered the visual character of the high peaks like Eagle Mountain and Sheep Mountain.
