Colorado Front Range

The Colorado Front Range is a colloquial geographic term for the populated areas of the state of Colorado in the United States which are just east of the foothills of the Front Range, from which the region takes its name. The region contains the largest cities and the majority of the population of Colorado, aligned in a north-south configuration on the western edge of the Great Plains, where they meet the Rockies. Geologically, the region lies mostly within the Colorado Piedmont, in the valley of the South Platte and Arkansas rivers on the east side of the Rockies.

The Colorado Front Range communities include (in a roughly north-to-south order):

• Fort Collins
• Greeley
• Loveland
• Longmont
• Boulder
• Denver and suburbs
• Castle Rock
• Colorado Springs
• Pueblo
