The Centennial Valley anchors this high-elevation landscape, where the waters of the West Fork Madison River and the expansive wetlands of the Red Rock Lakes National Wildlife Refuge meet. This 1997 Forest Service revision captures a sensitive ecological transition zone between the Beaverhead National Forest and protected wilderness areas. The map details a complex hydrologic network, from the alpine Hoodoo Pass and Snowshoe Pass down to the shores of Elk Lake and Swan Lake.
