The Columbia River pours more water into the Pacific Ocean than any other river in North or South America. In its 1,270 mile course to the Pacific Ocean, the Columbia flows through four mountain ranges -- the Rockies, Selkirks, Cascades, and coastal mountains -- and drains 258,000 square miles. The mainstem of the Columbia rises in Columbia Lake on the west slope of the Rocky Mountain Range in Canada. Its largest tributary, the Snake, travels 1,038 miles from its source in Yellowstone National Park in Wyoming before joining the Columbia.
