The Rockies, or the Rocky Mountains, are a major mountain range in North America, stretching over 3,000 miles from Canada to New Mexico. They are known for their stunning landscapes, diverse ecosystems, and outdoor recreational opportunities, including hiking, skiing, and wildlife viewing. The range is home to several national parks, such as Rocky Mountain National Park in Colorado. The Rockies were formed over millions of years through tectonic activity and erosion. They feature a variety of geological formations, including rugged peaks, deep valleys, and alpine lakes. The mountains are also rich in natural resources, including minerals and timber, and play a crucial role in the region's climate and water supply.
