2011 Map of Massacre Mountain

About this map

Massacre Mountain dominates this high-altitude landscape in Custer County, Idaho, where drainage patterns define the rugged topography. The central watershed is anchored by Long Lost Creek, which flows past the dramatic geological feature of Hell Canyon. This 2011 survey captures a wilderness area punctuated by small alpine water bodies, including Swauger Lakes to the northwest and the centrally located Shadow Lakes. To the southwest, Castle Peak stands as a primary landmark, overlooking the headwaters of Upper Cedar Creek. The mapping of these drainages, from Massacre Creek to the various branches of Wet Creek, illustrates the complex hydrological network of the Lost River Range. For researchers, the map provides a clear record of naming conventions and geographic landmarks in this secluded section of the Salmon-Challis region.
