The Arches National Park is a 310 sq. km area made up of natural sandstone arches and is located north of Moab in the state of Utah, USA. This National Park received its name because of the 2,000 natural sandstone arches that were formed because of the location of the park. Lying atop an underground evaporate layer or salt bed that was deposited more than 300 million years ago, the thousands of feet deep salt bed helped in the creation of spires, arches, balanced rocks, sandstone fins and eroded monoliths in the area.
