Angel Arch, Natural arch in The Needles, Canyonlands National Park, United States

Angel Arch is an eroded fin of Cedar Mesa Sandstone in a side canyon of Salt Creek Canyon, in the Needles District of Canyonlands National Park. The top of the formation stands 450 feet (140 m) above the canyon floor, and the opening measures 135 feet (41 m) high and 120 feet (37 m) wide. The sandstone is the remains of coastal sand dunes deposited about 245–286 million years ago, during the early Permian period.

The formation received its official name of Angel Arch in 1963 when the United States Board on Geographic Names replaced its previous name Pegasus Arch. This naming came from the visual appearance of the rock formation resembling a winged figure.

The arch's name comes from its outline: a figure with folded wings standing with its back to the opening. Before the U.S. Board on Geographic Names adopted Angel Arch in 1963, the feature was called Pegasus Arch. The first recorded ascent of the arch was made in June 1993 by John Markel and Kevin Chase.

The hike to reach this arch is long and demanding, requiring good physical fitness and proper equipment for desert hiking. Visitors should bring plenty of water, food, and navigation tools to stay safe on the route.

The arch's shape resembles an angel standing with folded wings and its back toward the opening, which inspired its name. This visual similarity becomes clearer when viewed from different angles along the approach trail.
