Arches National Park, located in eastern Utah, features more than 2,000 natural sandstone arches, including Delicate Arch, which is featured on the Utah license plate. The olympic torch even passed through Delicate Arch in 2002. The famous arches were formed from a sandstone layer deposited by an ancient sea. Over time, the salt underneath the sandstone forced it to rise and crack. The rising sandstone was exposed to wind, precipitation and erosion, which resulted in the formation of the arches.
