Washington and Oregon are two of the more diverse regions of the United States. The terrain includes glaciated peaks, active volcanoes, desert plains, alpine rainforest, Pacific coastline, and the Columbia Gorge. From a mountaineer’s perspective, the most exciting terrain resides in the north and west portions of these two states, which include the rugged, glaciated peaks and the Cascade volcanoes.

The Cascade volcanoes are the most famous high-altitude terrain. These volcanoes include Mount Rainier, Mount Baker, Mount Adams, Mount St. Helens, and Mount Hood.

The gem of the Cascade volcanoes is Mount Rainier. At 14,411 feet, Mount Rainier rises from the sea level terrain of Seattle, and dominates the skyline from a great distance. Seventeen mountaineering routes cover the flanks of Mount Rainier, entertaining amateur and expert climbers alike. Mount Rainier is internationally recognized for its rugged glaciers, superb scenery, demanding terrain, and volatile climate. The mountain serves as a training ground for international expeditions in the Andes and the Himalayas.
