About this map

Centennial Valley serves as a stark topographical divide in this late 20th-century survey, separating the high peaks of the Beaverhead National Forest from the expansive wetlands of the Red Rock Lakes National Wildlife Refuge. To the north, the terrain climbs sharply toward Patchtop Mountain and along Landon Ridge, where drainage from Snowshoe Creek feeds the valley floor. Landon Camp sits at the northeastern edge, marking a point of human activity near the boundary between Madison and Beaverhead counties.

The southern half of the map is dominated by the aquatic environment of Lower Red Rock Lake, protected within the Red Rock Lakes Wilderness. The intricate network of marshes and smaller water bodies, such as those near Matsingale Creek, highlights the importance of this high-altitude sanctuary for migratory birds. The map also records minor industrial traces like a Gravel Pit and a lone Water Tank, contrasting the primitive wilderness with necessary local infrastructure.
