1963 Map of Little Antelope Flat

About this map

Pahsimeroi Mountains and the Lost River Range converge in this high-altitude Custer County landscape, where the Challis National Forest boundary cuts through a complex system of basins and springs. The map documents a high-desert environment defined by seasonal water sources and livestock or hunting access routes, such as the Hole-in-Rock Trail and numerous unnamed jeep trails. Little Antelope Flat occupies the lower southern reaches of the quadrangle, serving as a primary drainage point for the surrounding highlands, including Warm Spring Creek and Hole-in-Rock Creek. Notable landmarks like Table Mtn and Red Hill provided essential visual navigation for those traversing the remote cattle and pack routes of the early 1960s. The naming of Spud Basin and Gooseberry Spring reflects a local nomenclature tied to the practical resources and geography of central Idaho.
