In which year was the Arches National Park in the U.S. established?

Located in the eastern part of the state of Utah, is a U.S. national park adjacent to the Colorado River just north of the city of Moab. It is in a high desert area located on the Colorado Plateau, named Arches National Park. Originally established as a national monument and park in 1929, in total it includes 76,679 acres (118,811 square miles; 31,031 ha; 310.31 km2). The National Park Service reported that as of 2018, a total of 1,663,557 visitors enjoyed visiting the park.

Some park features include its highest elevation at 5,653 feet (1,723 m) at Elephant Butte plus the fact that the park contains the highest density of natural arches in the world, attracting professional and amateur photographers from around the globe. Other features include Balanced Rock the size of 3 school busses, Delicate Arch, a lone-standing arch which has become a symbol of Utah, and Devils Garden displaying multiple arches and columns along a ridge.

The formation of the arches is due to the fact that the park lies above an underground evaporative layer or salt bed. This salt bed is thousands of feet thick in places and was deposited in the Paradox Basin of the Colorado Plateau some 300 million years ago.

The park receives an average of less than 10 inches (250 mm) of rain annually.

Evidence of human habitation has been found going back 10,000 years ago subsequent to the last ice age.
