In 1922, Olaus Murie entered Alaska to study caribou and wildlife ecosystems

Olaus Murie began studying Alaskan caribou in 1922, which influenced ecological wildlife understanding. His brother Adolph later investigated wolves and Dall sheep, challenging predator control assumptions. Adolph's research examined species interactions within the wider ecosystem of Mount McKinley. This work helped shift park management away from viewing predators solely as pests. The Muries' ecological approach continues to inform Denali's conservation efforts today.
