joined the U.S. Bureau of Biological Survey (now the U.S. Fish and Wildlife Service) in 1920 as a wildlife biologist, spending the next 6 years in the field with his brother Adolph Murie, studying Alaskan caribou, mapping migratory routes and estimating numbers. He married Margaret Thomas in 1924 in Anvik, Alaska. They spent their honeymoon tracking caribou through the Koyukuk River region. Books and articles In 1927, the Biological Survey assigned Murie to research the Jackson Hole elk herd, resulting in the classic publication The Elk of North America. He also authored six other major publications, including Alaska-Yukon Caribou (North American Fauna [NAF] No. 54, 1935); Food Habits of the Coyote in Jackson Hole, Wyoming (1935); Field Guide to Animal Tracks (1954); Fauna of the Aleutian Islands and Alaska Peninsula (NAF No. 61, 1959); and Jackson Hole with a Naturalist (1963). Wapiti Wilderness (with his wife, Mardy Murie) was published posthumously, in 1966. Research, service, and wildlife organizations Research Canada One of Murie’s first experiences collecting specimens and conducting research was in 1914–1915 and 1917 in Canada. Hired by W. E. Clyde Todd, the curator of birds at the Carnegie Museum of Natural History, and accompanied by Native American guides Paul Commanda, William Morrison and Jack (Jocko) Couchai, Murie embarked on his apprenticeship to study wildlife in Canada in 1914. While on this trip, Murie had numerous jobs and expectations. Murie was responsible for collecting bird, rodent and larger mammal specimens, as well as sketching and taking photographs of different organisms and environments. To do so, Murie was required to preserve and label not only animal skins but also rolls of film that was to be given to Carnegie Museum. During his time in Canada, Olaus Murie travelled to various locations and became accustomed to the harsh environment of the Arctic. Murie decided to stay an extra winter in Canada to gain more experience, despite the departure of his colleagues. Murie used this additional time to collect more animal samples as well as explore the ecological and cultural similarities and differences of the Hudsonian and Arctic life zones. Two years later, Murie returned to Canada with Clyde Todd, Alfred Marshall, a wealthy businessman, and guides Paul Commanda, Philip St. Onge and Charles Volant. The trip was ambitious, as they proposed to travel 700 miles north across Labrador, an expedition that had never been done before. They began by following the
