About this map

Bayhorse and Clayton serve as the primary human anchors in this rugged section of central Idaho, surveyed between 1927 and 1929. The region’s economic identity is defined by significant high-elevation mining operations, including the Ramshorn Mine and Beardsley Mine located near the canyon walls of Bayhorse Creek. The rugged geography of the Challis National Forest is punctuated by deep basins and peaks such as Bald Mtn and Ramshorn Mtn.

Evidence of early infrastructure is found at the Livingston Mine Power Plant and along the Challis-Mackay Stage Road. The map documents a transition in land use, showing the Big Lost River Game Preserve and the Clayton Ranger Sta alongside traditional mining and grazing lands. Water is central to the landscape, from the winding Salmon River to isolated high-country waters like Herd Lake and Jimmy Smith Lake.
