2020 Map of Big Horn Mountain

About this map

Beaverhead National Forest covers much of this Madison County landscape, where the high ridges of the Gravelly Range dominate the topography. The high-altitude environment is defined by a network of drainage systems, including the E Fork Ruby River and Elk River, which carve through the terrain near Black Butte. This 2020 survey reveals the complex hydrologic and topographic features of the region, from the steep walls of Beartrap Canyon to the alpine waters of Wall Cr Lake and the Klatt Reservoir. The map illustrates a landscape managed for conservation and resource use, crisscrossed by the Gravelly Range Rd and various forest tracks. Prominent peaks such as Marmot Mtn, Big Horn Mtn, and Cave Mtn serve as significant landmarks for those navigating these high basins.
