A little less than one half of the total land area of Colorado is flat and rolling land. From the base of the Rocky Mountains East to the borders of Nebraska, Kansas and Oklahoma, the Colorado landscape is filled with farms and ranches.
The Western Slope is the Western portion of the Continental Divide and was (and still is) carved out by the Colorado River.
Some of Colorado's most notable ski areas (Aspen, Breckenridge, Vail, Crested Butte, Steamboat Springs and Telluride) are all located in the Western Slope.

WESTERN SLOPE
Colorado is technically a desert state even though it highlights the Rocky Mountains with 54 peaks that are over 14,00 feet in elevation above sea level, commonly referred to as "Fourteeners". Mount Elbert, located roughly in the center of the state is the tallest peak in Colorado standing in at 14,440 feet.
Colorado's Rocky Mountains are the home to many ski resorts. A list of resorts and current conditions can be found here.
