Denali park rangers maintain a constant effort to keep the wildlife wild by limiting the interaction between humans and park animals.

Prehistory and protohistory

An immense collection of cultural sites gives more and more clues as to what and who used to live there. Thousand of years ago, grassland was abundant, and mammoths utilized the flat Mammoth Steppe to move and graze. Around 11,000 to 13,500 years ago, these grasslands shrunk and woody shrubs began to appear. Back then, the North-Alaskan Range was predominantly ice free.
