Nature and Science

Denali National Park and Preserve is a dynamic intact ecosystem that is both inspiring and complex. The landscape is not static--as landslides, glacially-fed braided rivers, and moving glaciers attest. There are also human impacts on the land, such as changes in air quality (air-borne contaminants) and climate.

Explore the topics below to learn general information about each. Check out our science and research, if you're interested in learning about what studies occur in the park, and what those studies discover about the park's flora, fauna and human history.
