This panoramic photograph was taken by James Blakeway. It features a view of the Delicate Arch, which balances at the edge of a canyon and is one of the most visited sites at the Arches National Park. In 1929, President Herbert Hoover set aside Arches as a National Monument. Arches remained a National Monument until 1969, when President Richard Nixon signed a bill making it a National Park. Water and ice, extreme temperatures, underground salt movement and 100 million years of erosion are responsible for the scenery of Arches National Park. There are more than 2000 cataloged arches in the area.
