Skilloot Indians. A Chinookan tribe found by Lewis and Clark in 1806 residing on both sides of Columbia river in Washington and Oregon, above and below the entrance of Cowlitz river, and numbering in all 2,500 souls. The Hullooetell may have been a band of them . They were among the tribes almost exterminated by the fever epidemic of 1823. Later their principal village was Cooniac, at Oak Point, Washington. In 1850 Lane placed their number at 200, but as a tribe they disappeared from view a few years later. The Seamysty appear to have been a division.
