1958 Map of Arsenic Mountain

USGS Topo · Published 1984

About this map

Arsenic Mountain dominates this high-altitude landscape where the Sun River cuts through the Southern Front of the Rockies. In the late 1950s, this area served as a critical intersection of wilderness management and recreation within the Lewis and Clark National Forest. The presence of the Sun River Game Preserve and the Sorrell Guest Resort suggests a mid-century economy built on conservation and seasonal tourism. Along the river banks near Gibson Reservoir, small outposts like White Cabin, KL Ranch, and the Sorrell Guest Resort provided access points for those navigating the extensive network of Pack Trails. The topography is marked by significant drainages such as Arsenic Creek and Blacktail Creek, which feed into the reservoir system behind the Reclamation Flats.
