The Largest Collection of Natural Arches on Earth - Arches National Park - USA

Entrada and Navajo sandstone has been sculpted by erosion into a whimsical rock garden that includes the largest collection of natural arches on earth, as well as windows, pinnacles, spires, fins, balanced rocks, and pedestals.Water and ice, extreme temperatures and underground salt movement are responsible for the sculptured rock scenery of Arches National Park. On clear days with blue skies, it is hard to imagine such violent forces, or the 100 million years of erosion that created this land that boasts the greatest density of natural arches in the world. The more than 2,000 cataloged arches range in size from a three-foot opening, the minimum considered an arch, to the longest one, Landscape Arch, which measures 306 feet from base to base. New arches are being formed and old ones are being destroyed. Erosion and weathering are relatively slow but are relentlessly creating dynamic landforms that gradually change through time. Arches National Park is open year round. The majority of park visitors come March through October, with lowest visitation in December and January. You can enjoy sightseeing by personal car, hiking, biking (established roads only), picnicking (3 designated picnic areas in park), and camping.
