A 9,565-foot granite shoulder of the Front Range, rising west of Colorado Springs above the Broadmoor and the Cheyenne Mountain Zoo. The mountain is best known as the granite vault that holds the NORAD complex, carved into its core in the early 1960s. The state park at its base opened in 2006 with 20 miles of trail and a view east across the Great Plains that runs, on clear mornings, almost to Kansas.
