The Centennial Valley anchors this high-elevation landscape where the Beaverhead Mountains meet the waters of the Red Rock Lakes National Wildlife Refuge. The map traces a complex network of high-country drainage, from the West Fork Madison River in the north to Raynolds Creek and the marshy expanses of Swan Lake in the south. This area serves as a critical hydrological and wildlife corridor, marked by specialized features like the Lookout Tower and various isolated watering points such as Two Drink Springs and Antelope Pond.
