The Cañon City area's high points have been literal, starting with the magnificent Royal Gorge. Here the Royal Gorge Bridge crosses the Arkansas River, 1,053 feet below, as the highest suspension span in the world. From the scenic and geological diversity to some of the initial oil discoveries in the United States, this Fremont County seat has been a hub of coal mining and archaeological discoveries, particularly of dinosaur remains. The temperate weather means long growing seasons, celebrated each May by the Blossom and Music Festival. Once a commerce center supplying food, lumber, and other goods to surrounding gold towns—from Cripple Creek to Leadville—Cañon City also once was a silent-film capital, the base for hundreds of motion pictures produced after the beginning of the 20th century. Prisons and their residents have always been a huge part of Cañon City history; the first territorial prison was located here and many more prisons operate here today.
