Nickname for Denver, CO, derived from its official elevation of 5280 feet, or one mile, above sea level. This fact is prominently noted on several local landmarks; for example, the Colorado State Capitol building has a step in front of it marked as being precisely 5280 feet in elevation. Also, a row of seats at Coors Field in LoDo that is at precisely 5280 feet elevation uses a contrasting color to mark this fact.
