The Mountain (Tsethaottine, Chitra-Gottineke), an Athapaskan-speaking group, live in the Mackenzie Mountains in the basin of the Keele (Gravel) River, the region of Willow Lake, and the country between the Mackenzie River and Lakes La Martre, Grandin, and Tache, in the western part of the Mackenzie District in the Northwest Territories of Canada. There were about one hundred Mountain Indians in 1971.
