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 1Original Journal of Lewis and Clark, III, 196; vi, 68, 117, 1905 . They were among the tribes almost exterminated by the fever epidemic of 1823.

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.
Cathlamet Indians. A Chinookan tribe formerly residing on the south bank of Columbia River near its mouth, in Oregon. They adjoined the Clatsop and claimed the territory from Tongue point to the neighborhood of Puget Island. In 1806 Lewis and Clark estimated their number at 300. In 1849 Lane reported 58 still living, but they are now extinct. They seem to have had but one village, also known as Cathlamet. As a dialect, Cathlamet was spoken by a number of Chinookan tribes on both sides of the Columbia, extending up the river as far as Rainier. It is regarded as
Chinook Indians. The Chinook were located on the north side of the Columbia River from its mouth to Grays Bay (not Grays Harbor), a distance of about 15 miles, and north along the seacoast to include Willapa or Shoalwater Bay. Ray (1938) makes a separate division to include the Shoalwater Chinook but it will be more convenient to treat them under one head. It is understood that they differed not at all in dialect.
