The Kaska or Kaska Dena are a First Nations people of the Athabaskan-speaking ethnolinguistic group living mainly in northern British Columbia and the southeastern Yukon in Canada. The Kaska language, originally spoken by the Kaska, is an Athabaskan language. The Kaska Dena constituted five local bands: Tu tcogotena (Tu’tcogotena) or Tu cho gha nugga dhal (″Big Water Dwellers″) are the Dena people that occupy the Tucho (Frances Lake) and the Tucho Tue (Frances River) area stretching to the Hyland and Smith rivers. They hunted also the Too-Ti (Liard) and Tucho Tue (Dease River) areas. Also known as McDame Post Kaska or Fort McDame Kaska because they traded at the McDame Post (Fort McDame) trading post (at the mouth of McDame Creek into the Dease River); also referred to as Frances Lake Kaska in some sources. Ki stagotena (Ki’stagotena) or Tsetotena (Tsay tow tena) (″Mountain Dwellers″) dominated the south and south east of the Natitu a gotena Kaska. Their traditional range included the valleys of the Dease River south from Net I tue to the northern part of Dease Lake where a natural divide separated them from the inland neighbours. Ki stagotena living along Duna za (McDames), meaning “pure place where people stay”, above its junction with the Dease River was also known as Ozanna, “people of the same blood”. Also known as Dease River Kaska. Espatodena (E)spa’totena) or Espa tah dena (″Dwellers Among the Wild Goats″) and Gata otena (″People Who Hunt Rabbits″) are concentrated within a range east of the Tu tcogotena Kaska north of Tsa Tue (Beaver River) and the Nahanni River. They also hunted at the junction of the Atsonne Tue (Moose Dung Water River/Coal River) and Tyagacho (Big River/Liard). Naatitu a gotena (Natitu?a’gotena) or Na aw ti to a gotena (″Dwellers at a Sharp Mountain Where a Little River Starts″) occupied the head water country portion of the Liard River called Net I Tue, down to the Canyon above Daylu (Lower Post) which means “a place where we gather to trade”. They made seasonal migrations to the salmon runs at Tu disdis Tue (Pelly River) which means “you can see clearly into the deep water”. Seasonal fishing also was done at Tuts Algua (Watson Lake) or Lu cho, and game was harvested along Agedze Tue (Hyland River) which means “too much game”. The Tu tcogotena Kaska also used the Hyland River and called it Bath-o-too-a (Dangerous
