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.

In the latter case we must suppose that they extended to the south side of the Columbia.
