Monument Valley (valley of the rocks) is a region of the Colorado Plateau characterized by a cluster of vast sandstone buttes, the largest reaching 1,000 ft (300 m) above the valley floor.
It is located on the Arizona-Utah state line. The valley lies within the range of the Navajo Nation Reservation and is accessible from U.S. Highway 163
Monument Valley has been featured in many forms of media since the 1930s
Director John Ford used the location for a number of his best-known films, and thus, in the words of critic Keith Phipps, “its five square miles” have defined what decades of moviegoers think of when they imagine the American West.”
Monument Valley is officially a large area that includes much of the area surrounding Monument Valley Navajo Tribal Park, a Navajo Nation equivalent to a national park
Arches National Park is a U.S. National Park in eastern Utah.
The park is located on the Colorado River 6 km North of Moab, Utah.
It is known for containing over 2000 natural sandstone arches, including the world-famous Delicate arch, in addition to a variety of unique geological resources and formations.
The park is located just outside of Moab,Utah, and is 76,359 acres (30,901 ha) in area.
Its highest elevation is 5,653 feet (1,723 m) at Elephant Butte, and its lowest elevation is 4,085 feet (1,245 m) at the visito center.
Forty-three arches have collapsed due to erosion since 1970. The park receives 10 inches (250 mm) of rain a year on average
Administered by the National Park Service, the area was originally named a National Monument on April 12, 1929. It was redesignated as a National Park on November 12, 1971.
The park has over 2,000 natural stone arches, in addition to hundreds of soaring pinnacles, massive fins and giant balanced rocks.
This red rock wonderland will amaze you with its formations, refresh you with its trails, and inspire you with its sunsets.
In the late 1800s, John Wesley Wolfe, a disabled Civil War veteran, and his son, Fred, built a homestead in what is now Arches National Park. A weathered log cabin, root cellar, and corral remain as evidence of the primitive ranch they operated for more than 10 years
