The primary mountain range in North America is the Rocky Mountains. This vast range extends from northern Canada through the United States and into Mexico, covering approximately 3,000 miles. The Rockies are known for their rugged terrain, stunning landscapes, and diverse ecosystems. They contain numerous national parks, such as Rocky Mountain National Park and Yellowstone, which attract millions of visitors each year for activities like hiking, skiing, and wildlife viewing. The formation of the Rockies began around 80 million years ago during the Laramide Orogeny, and they continue to be a prominent feature of North America's geography.
