2020 Map of Moffett Springs

About this map

Moffett Springs and Barney Hot Springs anchor this high-elevation landscape where the Lemhi Range meets the Little Last River Valley. The transition from the steep, forested slopes of the Challis National Forest to the lower-lying Mud Flats is sharply defined, with numerous drainages like Big Gulch and Summerhouse Canyon carving through the terrain. The presence of geothermal features and various springs, including Iron Springs, suggests a complex hydrologic network that has long shaped land use in this part of Custer County. Transportation through the area is dictated by the topography, with Sawmill Canyon Road following the contours of Sawmill Canyon while the Pahimeroi Rd provides access to the western valley floor. The map also traces the county line between Lemhi Co and Custer Co as it crosses the high peaks near Iron Creek Point.
