Delicate Arch, Natural arch in Arches National Park, US

Delicate Arch is a freestanding natural arch of Entrada Sandstone in Arches National Park, Utah, rising 52 feet (16 m). Two thick, roughly vertical legs of reddish-orange rock lean toward each other and meet at a curved span; horizontal sedimentary bands run across the rough surface, and a flatter cap rests on top.

Delicate Arch was not part of the original Arches National Monument designated in 1929; it was added when the monument was enlarged in 1938. Frank Beckwith, leader of the Arches National Monument Scientific Expedition, gave the arch its current name during the winter of 1933–1934. In the 1950s the National Park Service considered coating the arch with clear plastic to slow erosion, but abandoned the idea as impractical.

Cowboys called the formation "the Chaps" and "the Schoolmarm's Bloomers" before Frank Beckwith, leader of the 1933–1934 Arches National Monument Scientific Expedition, gave it its present name. The arch appears on Utah license plates and on a stamp marking the state's 1896 admission centennial, and the 2002 Winter Olympics torch relay passed beneath it. The United Utah Party adopted it as its logo in 2017.

The trail starts at Wolfe Ranch parking area and covers 2.5 kilometers (1.5 miles) with an elevation gain of roughly 150 meters (480 feet). The final section crosses open slickrock without railings or markers, so sturdy shoes and plenty of water are important.

Wind and temperature shifts widen tiny cracks in the stone year after year, slowly reshaping the formation over time. Geologists estimate such arches may stand anywhere from a few hundred to several thousand years before collapsing.
