Glen Canyon, Glen Canyon National Recreation Area

Glen Canyon is a natural canyon carved by a 169.6-mile length of the Colorado River, mostly in southeastern and south-central Utah, in the United States. Glen Canyon starts where Narrow Canyon ends, at the confluence of the Colorado River and the Dirty Devil River. A small part of the lower end of Glen Canyon extends into northern Arizona and terminates at Lee's Ferry, near the Vermilion Cliffs. Like the Grand Canyon further downstream, Glen Canyon is part of the immense system of canyons carved by the Colorado River and its tributaries. ()
