where does the rocky mountain range start and end
Rocky Mountains The Rocky Mountains, commonly known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than 3,000 miles (4,800Â km) from the northernmost part of British Columbia, in western Canada, to New Mexico, in the Southwestern United States. Within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges and the Cascade Range and Sierra Nevada, which all lie further to the west.
Geography of North America The western mountains have split in the middle, into the main range of the Rockies and the Coast Ranges in California, Oregon, Washington, and British Columbia with the Great Basin (a lower area containing smaller ranges and low-lying deserts) in between. The highest peak is Mount McKinley/Denali in Alaska. The geographic center of North America is approximately "6 miles west of Balta, Pierce County, North Dakota" at 48⁰ 10′north, 100⁰ 10′west,[13] and a 15-foot (4.5 m) field stone obelisk in Rugby, North Dakota (~15 miles or 25 km away) claims to mark the center.[citation needed]
