Red Rock Lakes National Wildlife Refuge is a remote refuge located in the high altitude of the Centennial Valley, in the southwestern region of the U.S. state of Montana. Adjacent to Gallatin National Forest and near Yellowstone National Park, the refuge is an integral part of the Greater Yellowstone Ecosystem. Red Rock Lakes is best known for being the primary location for the efforts saving the trumpeter swan from extinction, which by 1932 had fewer than 200 known specimens in the United States and Canada. By the year 2002, an estimated 3,000 trumpeters were wintering on the refuge, many having migrated south from their summer range in Canada. The trumpeters are now so plentiful that efforts are being undertaken to help them reestablish historical migratory routes to areas further south in the Rocky Mountains and the Great Basin region. The elegant trumpeter swan is North America's largest waterfowl, with a wingspans of 8 feet (2.6 m) and they can weigh up to 30 pounds (13 kg).
The altitude of the refuge ranges from 6,600 feet (2,000 m) to almost 10,000 feet (3,000 m) and consists of 65,810.25 acres (266.32 km2) of high altitude prairie and forested uplands. The lakes and cold water marshlands provide a relatively uncommon wetland environment favored by certain waterfowl and predatory birds such as the bald eagle and peregrine falcon. There have been sightings of over 250 different bird species in the refuge and over 100 different species are known to nest here. There is reportedly 20 nesting pairs of bald eagles on the refuge and there have been several sightings of the endangered whooping crane. Numerous mammals can also be found here such as the black bear, moose, elk (wapiti), mule deer, pronghorn, beaver, mink and badger. It is also believed that the grizzly bear and wolf packs may infrequent the refuge and limited sightings of wolverine have been recorded.
