About this map

Alturas Lake and Pettit Lake define the western edge of the Sawtooth Valley in this modern survey, marking a landscape heavily shaped by winter recreation and high-elevation hydrology. The map details an extensive network of specialized trails within the Sawtooth National Forest, including the Sheep Thrills Ski and Wapati Ski loops, illustrating how the area has been organized for seasonal use. Near the center, Perkins Lake sits tucked between these alpine waterways and the Alturas Creek Road.

Cultural landmarks are concentrated along the valley floor, where the Salmon River begins its course. The presence of the Sawtooth Cemetery near Beaver Creek Road provides a specific point of interest for genealogists, while the Smiley Creek Airport serves as a vital transit point for this remote Idaho corridor. The boundary between Custer County and Blaine County bisects the terrain, crossing through Horton Peak and the drainage of Smiley Creek.
