2017 Map of Little Antelope Flat

About this map

Little Antelope Flat occupies a significant plateau within the Custer County high country, as documented in this 2017 survey. The landscape is defined by the convergence of major geographic features, including the eastern reaches of the Challis National Forest and the rugged slopes of the Lost River Range and Pahsimeroi Mountains. The hydrologic network is anchored by Warm Spring Cr, which flows past its namesake Warm Spring, while Hole-in-Rock Cr and Lime Cr drain the surrounding basins. This map illustrates the intersection of high-altitude water sources and cattle-grazing territory, where landmarks like Table Mtn and Red Hill provide orientation across the remote terrain. Notable local features like Spud Basin and Devil Canyon suggest the varied geological character of this section of the Idaho wilderness.
