In Colorado, the Rocky Mountain Front extends from the west-northcentral part of the border with Wyoming south to the city Pueblo and the Arkansas River. Peaks within the front include Pikes Peak, Mount Evans, and Longs Peak. Just east of the Rocky Mountain Front is the Colorado Piedmont, and within the Piedmont is the most heavily urbanized part of the United States between Chicago and the West Coast. The only pass through the Rocky Mountains in the area is the Tennessee Pass.
