Monument Valley Navajo Tribal Park is contained within Monument Valley and is part of the Colorado Plateau. It is characterized by a cluster of vast and iconic sandstone buttes, the largest reaching 1,000 ft (300 m) above the valley floor. Located on the southern border of Utah with northern Arizona, near the Four Corners area, the valley lies within the range of the Navajo Nation Reservation.
The floor of Monument Valley is largely Cutler Red siltstone or its sand deposited by the meandering rivers that carved the valley. The valley's vivid red color comes from iron oxide exposed in the weathered siltstone. The darker, blue-gray rocks in the valley get their color from manganese oxide.
Monument Valley is the most common sight that portrays the Wild West in movies. It has appeared in Westerns by director John Ford. It has also featured in cartoons such as Chip n' Dale's Rescue Rangers, Metallica's music video I Disappear, and science fiction movies such as Back to the Future III. The rock band called Eagles used Monument Valley on the cover of their 1985 UK 'Best of' album.
