Cowlitz Tribe
Cowlitz Indians. A Salish tribe formerly on the river of the same name in south west Washington. Once numerous and powerful, they were said by Gibbs in 1853 to be insignificant, numbering with the Upper Chehalis, with whom they, were mingled, not more than 165. About 1887 there were 127 on Puyallup Reservation, Washington. They are no longer known by this name, being evidently officially classed as Chehalis.
