Rocky Mountains Colorado

• The Rocky Mountains are a western region of the United States of America, and offer skiing and snowboarding in the winter, and road and mountain biking, hiking, camping, kayaking, horse-back riding, and white water rafting in the summer. Rocky Mountains, by name the Rockies, mountain range forming the cordilleran backbone of the great upland system that dominates the western North American continent. Generally, the ranges included in the Rockies stretch from northern Alberta and British Columbia southward to New Mexico, a distance of some 3,000 miles (4,800 km). In places the system is 300 or more miles wide. Limits are mostly arbitrary, especially in the far northwest, where mountain systems such as the Brooks Range of Alaska are sometimes included. The Rockies are bordered on the east by the Great Plains and on the west by the Interior Plateau and Coast Mountains of Canada and the Columbia Plateau and Basin and Range Province of the United States.
