Contiguous United States
The ecosystem of the Beartooth Mountains is one of the most unique in the Contiguous United States partly due to being part of the Greater Yellowstone Ecosystem. This space allows a great diversity with 34,375 square miles of nearly intact wilderness. With the protection to the terrestrial habitats all of the bodies of water are classified as Outstanding National Resource Waters, giving them the highest protections under the Clean Water Act. The cleanliness of the bodies of water led them to be used as a benchmark to compare others in the northern Rocky Mountains. Most of the current species are currently protected.
