Columbia River [SEP] Introduction
The Columbia River (Upper Chinook: ' or '; Sahaptin: "Nch'i-Wàna" or "Nchi wana"; Sinixt dialect" ") is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the US state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province.
