Since their trading center was traditionally located at Daelyu, the "Lower Post" trading post was officially opened there in 1876, and they were therefore referred to as Lower Post Kaska; in some sources they are also referred to as Upper Liard Kaska. Tse lona (Tse’lona) or Tsay lona (″Mountain Top″) populated the area south and east of the Ki stagotena. They lived and hunted the Rocky Mountain trench headwaters and valleys, the Kechika range over to the Toad River area and north to the Flat River.
