The Sand Dune Arch is a very wonderful site for hikers, especially children in Arches National Park in Utah. The Aches became a national monument before it became a national park in 1971 by President Richard Nixon. The region was once home to Native Americans, thousands of years ago. The hike is very short, and it gives multiple opportunities for hikers to play in the sand. That gives rise to its name, Sand Dune, because of its sandy slot between two fins. The sand is fine and reflects a pinkish-red hue which is an indication of its sandstone origin.
