Chinookan peoples
Chinookan peoples include several groups of Indigenous people of the Pacific Northwest in the United States who speak the Chinookan languages. Since at least 11,500 BCE, Chinookan peoples and their ancestors have resided along the upper and Middle Columbia River (Wimahl) ("Great River") from the river's gorge (near the present town of The Dalles, Oregon) downstream (west) to the river's mouth, and along adjacent portions of the coasts, from Tillamook Head of present-day Oregon in the south, north to Willapa Bay in southwest Washington.
