Native American Tribes series.
Taidnapam
Also called Upper Cowlitz. The Taidnapam on the headwaters of Cowlitz River, and perhaps extending over into the headwaters of the Lewis River, belonged to the Shahaptian division of the Shapwailutan linguistic family. Mooney estimates the population of the Taidnapam and the Klickitat together at 600 in 1780, but extinct as independent tribes by 1907.
