Tracking the movements of Denali's wolves

The wolves of Denali National Park (formerly Mount McKinley National Park) were the subject of some of the earliest research on wolf ecology. From 1939 to 1941, Adolph Murie performed groundbreaking studies of wolves, observing wolves and their prey and collecting wolf scats and prey remains. His work resulted in one of the first major scientific publications about wolves, The Wolves of Mount McKinley (Murie 1944). Continuing the research started by Murie, the National Park Service (NPS) began using aircraft to locate and count wolves in the 1960s (Prasil 1967, Singer 1986). Beginnin g in 1969, Go r d o n Haber used aircraft to make prolonged observations of wolf packs, studying their behavior and relations with prey species (Haber 1977).
