The native language spoken by the people of this First Nation is Southern Tutchone.
The Kluane people occupy a traditional territory that extends from the St. Elias Mountains in the south, bounded to the east by the southern end of Kluane Lake and the A'ay Chu (formerly Slims River), by the Ruby Range to the north, extending almost to the Nisling River, and on the west by the Yukon Alaska Border.
Growing from the shores of Kluane Lake in all directions is Ä sì Keyi, (My Grandfather’s Country) a boreal forest nation, that stretches to the Ruby and Nisling mountain ranges to the northeast and the St. Elias Mountains to the southwest.
The majority of the First Nation people from this area identify themselves as descendants of Southern Tutchone speakers and follow a matriarchal moiety system of two clans, Khanjet (Crow Clan) or Ägunda (WolfClan).
Other ancestors of the Kluane First Nation came from nations such as the Tlingit, Upper Tanana and Northern Tutchone.Within this region, the three main defining topographic feature are the St. Elias Mountains to the south and west, the Shakwak Trench, which includes Kluane Lake, and the Kluane and Ruby Range to the east and north, which are part of the Yukon Plateau.
