2013 Map of Obsidian
USGS Topo · Published 2013About this map
Sawtooth Valley and the surrounding wilderness of Custer County are defined by the winding course of the Salmon River and the small settlement of Obsidian. This high-altitude landscape is primarily managed by the Sawtooth National Forest and Challis National Forest, where drainages like Fourth of July Cr, Milky Cr, and Champion Cr flow through deep canyons. The map documents the layout of the Idaho Rocky Mountain Ranch and the open expanse of Decker Flat during the early 21st century.
