Humans began living in the watershed over 10,000 years ago. There were once many tribal villages along the lower river and in the area around its mouth ...

Chinook People
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. In 1805 the Lewis and Clark Expedition encountered the Chinook Tribe on the lower Columbia. The term "Chinook" also has a wider meaning in reference to the Chinook Jargon, which is based on Chinookan languages, in part, and so the term "Chinookan" was coined by linguists to distinguish the older language from its offspring, Chinuk Wawa. There are several theories about where the name "Chinook" came from. Some say it is a Chehalis word ''Tsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
