Urban sprawl from the developments in Broomfield, Colorado approach the majestic range of the Flatiron Mountains. Carpenters work on a new sledding attraction at the top of Vail Mountain which overlooks the Colorado Rockies and Vail Pass. The Flatirons are rock formations in the western United States, near Boulder, Colorado, consisting of flatirons. There are five large, numbered Flatirons ranging from north to south along the east slope of Green Mountain, and the term "The Flatirons" sometimes refers to these five alone. Numerous additional named Flatirons are on the southern part of Green Mountain, Bear Peak, and among the surrounding foothills. Taken at sunrise from a height of over 100 feet in Broomfield, Colorado.
