In page Yakutat, Alaska:

"

The original settlers in the Yakutat area are believed[citation needed] to have been Eyak-speaking people from the Copper River area. Tlingit people migrated into the region and the Eyak were assimilated into the tribe before the arrival of Europeans in Alaska. Yakutat was only one of a number of Tlingit and mixed Tlingit-Eyak settlements in the region. The others have been depopulated or abandoned.
