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.
