Grey Wolf in Snow Keychain

This image shows a grey wolf walking through the snow. The distribution of grey wolves has recently been restricted to the open tundra and forests of North America, primarily in Alaska, Canada and the northern United States. Grey wolves are highly adaptable and have been known to survive in all habitats in the Northern Hemisphere except for tropical forests. | "Smithsonian" and the Smithsonian logo are registered trademarks owned by Smithsonian Institution.
