The Coast Ranges runs along the pacific coast on the west side of the state, while the Cascade Range runs to the east vertically through the center of the state. Kettle River Range and Selkirk Mountains, part of the Rocky Mountains, are located along the northeast corner of the state. Mount Olympus, part of the Coast Ranges, sits nearly 8,000 feet above sea level. The Cascade Range contains Mount Rainier, a volcanic peak at over 14,000 feet above sea level, as well as several other volcanoes including Mount St. Helens.

The Coast and Cascade ranges cradle the Puget Sound Basin that contains several islands. Just east of the Cascade Range along the Idaho and Washington border is the Columbia Plateau, an area with an elevation between 600 and 2,000 feet above sea level that contains the Blue Mountains and lava beds. The Columbia River runs south from Canada through Washington's northeast corner, flows west to the Cascade Range, and moves south where it flows along the Washington and Oregon border to the Pacific Ocean.
