This study details the traditional land use of the Athabasca Chipewyan First Nation (ACFN) or K'ai taili Dene as described by 32 Elders, supplemented by additional historical and archaeological research. The Elder interview, held during 2001 and 2002, include descriptions of hunting, fishing, trapping and gathering, as well as legends and stories of the Chipewyan people. This study combines the first hand knowledge of the Elders with historical and pre- and proto-contact research in an effort to describe the land use of these people from the earliest times. The study includes an overview of the pre-contact and historical land use regions, an analysis of the recent land use areas, and a description and discussion of their land use activities. The knowledge of the Elders includes descriptions of the animals, birds and plants that were and are harvested. The ACFN Elders have also provided a discussion of some aspects of traditional knowledge, including oral traditions and legends, as well as cultural, spiritual and heritage sites and activities. Throughout this study it becomes apparent that the ACFN people have lost much of their opportunity to continue their traditional ways of life due to the infringements of settlers society in their traditional area of northeast Alberta which include Jackfish on the Delta, Birch River and the Park; Point Brule and Poplar Point on the Athabasca River; and Old Fort Point. This study includes many pictures to help tell the story of these people, as well as detailed maps, project methodology, and bibliography.
