2023 Map of Massacre Mountain

About this map

Challis National Forest encompasses this high-elevation terrain in Custer County, dominated by the massive presence of the Lost River Range. The landscape is defined by its drainage systems and glacial features, with numerous trails providing access to remote alpine basins. Notable waterways such as Long Lost Creek, Dry Creek, and Wet Creek carve through the steep topography, while higher elevations hold Swauger Lakes, Shadow Lakes, and Nolan Lake. The summit of Massacre Mtn and the prominent Castle Peak serve as significant navigational landmarks for the region. A network of primitive paths, including the Long Lost-Wet Creek Trl and Dry Creek Trl, illustrates the historical and modern reliance on these corridors for traversing the demanding environment between Hell Canyon and the surrounding peaks.
