The Rocky Mountains

The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch 3,000 mi (4,800 km) in a straight-line distance from the northernmost part of Western Canada, to New Mexico in the Southwestern United States. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The range's highest peak is Mount Elbert in Colorado at 4,401 metres (14,440 ft) above sea level.
