As reported by Lewis and Clark, the Chilluckittequaw Indians lay along the north side of Columbia River, in the present Klickitat and Skamania Counties, from about 10 miles below the Dalles to the neighborhood of the Cascades. Spier (1936) thinks they may have been identical with the White Salmon or Hood River group of Indians and perhaps both. In the latter case we must suppose that they extended to the south side of the Columbia.
Chilluckittequaw Indians (Chilû’ktkwa). A Chinookan tribe formerly living on the north side of Columbia river in Klickitat and Skamania counties, Washington, from about 10 miles below the Dalles to the neighborhood of the Cascades. In 1806 Lewis and Clark estimated their number at 2,400. According to Mooney a remnant of the tribe lived near the mouth of White Salmon river until 1880, when they removed to the Cascades, where a few still resided in 1895. The Smackshop were a subtribe.
