Arches National Park contains the world's largest concentration of natural stone arches.
The national park is located in eastern Utah, Usa.
The park is known for preserving over 2000 natural sandstone arches, including the world-famous Delicate Arch, in addition to a variety of unique geological resources and formations.

It is a desert, red and barren, filled with oddly eroded sandstone forms such as fins, pinnacles, towers, balanced rocks, and arches.
The park is has 31,000 hectares. Its highest elevation is 5653 feet (1723 m) at Elephant Butte, and the lowest 4085 feet (1245 m) at the visitor center.
43 arches have collapsed due to erosion since 1970. The park receives 250 mm of rain per year on average.
Administered by the National Park Service, the area was originally established as a National Monument on April 12, 1929. It was redesignated as a National Park on November 12, 1971.
In some areas, the forces of nature have exposed millions of years of geological history.
The extraordinary features of the park have created a landscape of contrasting colors and textures, different from any other in the world.
The rock layers reveal millions of years of erosion, deposition and other geological events. These layers continue to shape life in Arches today.
The climate is one of very hot summers, cold winters and very little rainfall. Even on a daily basis, the temperatures can vary up to 50 degrees.
