Columbia River
Aerial view of a large river winding through a mountainous gorge. It passes over a dam stretching in four segments from bank to bank across three intervening islands. Highways, passing by clusters of buildings here and there on both banks, run parallel to the river. Whitewater and foam curl downriver from one of the central segments.

Three-color map of the Columbia River watershed. The watershed is shaped roughly like a funnel with its wide end to the east and its narrow end along the border between Washington and Oregon as it nears the Pacific Ocean. The watershed extends into the western U.S. states of Washington, Oregon, Idaho, Nevada, Utah, Wyoming, and Montana, and the western Canadian province of British Columbia as far east as its border with Alberta. The river itself makes a hairpin turn from north-west to south in British Columbia and another sharp turn from south to west as it nears Oregon.
