2017 Map of Big Soldier Mountain

About this map

The Middle Fork Salmon River carves a deep path through this high-altitude wilderness along the border of Valley and Custer counties. This 2017 survey details a landscape where air access and river navigation define human movement, anchored by the Morgan Ranch Airport and Sulphur Creek Ranch Airport. The topographical detail captures the river's technical reaches, including Velvet Falls, Sulphur Slide Rapid, and the significant drop at Dagger Falls near the Boundary Creek Road Corridor. Spanning portions of the Boise National Forest and Challis National Forest, the map highlights prominent peaks like Big Soldier Mtn and Morehead Mtn. The transition between protected forest lands and the Soldier Basin reflects the area's ongoing use for backcountry aviation, river running, and remote resource management.
