About Denver
Denver is the capital of the western U.S. state of Colorado and the dominant city of the Rocky Mountain Region. Founded in 1858 as the placer gold mining camp known as the Cherry Creek Diggings, the "Mile-High City" is today the most populous city within a 560-mile (900 km) radius and the center of the Front Range Urban Corridor of more than five million residents.
