Location of the Pacific Coastal Ranges

The Pacific Coastal Ranges (Pacific Coast Ranges / Pacific Mountain System) form a nearly continuous mountain chain along the western edge of North America, from Alaska through Canada (Yukon, British Columbia) to the United States (Washington, Oregon, California). Extending ~4,800 km (3,000 mi), they include the Olympic, Cascade, Coast, Klamath, and Transverse Ranges, and are part of the larger North American Cordillera.
