The Rocky Mountains, often called the Rockies, are a major mountain range in western North America. They stretch over 3,000 miles from northern British Columbia in Canada to New Mexico in the United States. The range is known for its stunning landscapes, diverse ecosystems, and recreational opportunities, including hiking, skiing, and wildlife viewing. The Rockies are home to several national parks, such as Rocky Mountain National Park in Colorado and Banff National Park in Canada. These parks protect unique flora and fauna, including species like the bighorn sheep and grizzly bear. The mountains also play a crucial role in the region's water supply and climate.
