Mount McKinley National Park (the original 2 million acres established in 1917) was the first national park created to protect wildlife, including Dall's sheep.
Over 100 bird species call Denali home in summer, though far fewer overwinter in the park. Learn more about birds in Denali, view an online bird checklist, or read more about the following selection of birds.
The rivers and lakes most commonly seen by visitors provide habitat for limited species of fish. Additional species are found in more remote waters of the park.
Reptiles and Amphibians
There are no reptiles this far north; however, there is one lone amphibian species -- the wood frog. It is adapted for life in the far north: it freezes solid in winter, and then thaws in the spring! Learn more about wood frogs.
Did You Know?
Visibility is an important component of measuring Denali's air quality. Visibility data, such as that from the Wonder Lake camera, supplements chemical data from filter samples. Air here is still clean, but traces of pollution from local, regional and international sources exists on filter samples.
