Glen Canyon

Glen Canyon is a natural canyon carved by a 169.6-mile length of the Colorado River, lying mostly in south-eastern and south-central Utah. It begins where Narrow Canyon ends, at the confluence of the Colorado and Dirty Devil rivers; a small part of its lower end extends into northern Arizona and terminates at Lee's Ferry, near the Vermilion Cliffs. Like the Grand Canyon farther downstream, it forms part of the system of canyons carved by the Colorado River and its tributaries. In 1963 the reservoir of Lake Powell was created by the construction of the Glen Canyon Dam, in the Arizona portion of the canyon near the then new town of Page, inundating much of Glen Canyon under water hundreds of feet deep. The dam remains a central issue for modern environmentalist movements, and from the late 1990s the Sierra Club and other organisations renewed the call to dismantle it and drain Lake Powell in lower Glen Canyon. Glen Canyon and Lake Powell are managed by the U.S. Department of the Interior within Glen Canyon National Recreation Area.
