The Che:K’tles7et’h’ (Checleset, Cheklesaht) First Nation is positioned on the frontier between Nuu-chah-nulth- and Kwakwala-speaking territories, and its members traditionally spoke both language. They once occupied the shores of Checleset Bay but moved to nearby Mission Island in the 1950s. Today they live at Houpsitas on Kyuquot Sound, a village they share with the Ka:’yu:’K’t’h (Kyuquot) people, having formally amalgamated with that group in 1963. Both First Nations belong to the Nu-chah-nulth official newspaper, Ha-shilth-sa, translated the name Checleset as “people from the place where you gain strength.” The bay was named by the hydrographic service in the 1930s.
