The Rocky Mountains, also known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch 3,000 mi (4,800 km) in straight-line distance from the northernmost part of British Columbia, in western Canada, to New Mexico in the Southwestern United States. The northern terminus is located in the Liard River area east of the Pacific Coast Ranges, while the southernmost point is near the Albuquerque area adjacent the Rio Grande Basin and north of the Sandia–Manzano Mountain Range. Located within the North American Cordillera, the Rockies are distinct from the Cascade Range and the Sierra Nevada, which all lie farther to the west.
