2023 Map of Doublespring

About this map

The Pahsimeroi Mountains and the Lost River Range converge in this high-elevation corner of the Challis National Forest. This modern survey documents the complex drainage and transportation network of Custer County, anchored by the Pahsimeroi Valley and the steep corridor of Dead Cat Canyon. The landscape is defined by a web of Forest Service development roads and specialized backcountry routes, including Nat For Dev Rd 116 and the Trough Loop Trl. Remote water sources such as Rock Spring and the high-altitude Carlson Lake are critical landmarks for understanding the hydrology and land use patterns of this mountain terrain. The naming of features like Christian Gulch and the Donkey Hills Rd reflects a history of local exploration and resource management within the federal forest boundaries.
