The Columbia River Estuary is situated on the Oregon–Washington border and the Pacific Coast of the United States. It was traditionally inhabited by the Chinook Native Americans and discovered by settlers in 1788. The Estuary plays host to a plethora of species of marine and terrestrial flora and fauna, and multiple conservation organisations exist that maintain the area. Geologically, it is situated on a continental margin of the North American Plate.
