Landscape Arch is the longest arch in North America with a light opening of 306 feet (93.3 meters). This awe-inspiring expanse is only 6 feet (1.8 meters) in diameter at its narrowest. Large segments of the arch came crashing down in the 1990s – proof that the park’s landscape can change dramatically in a instant.
Landscape Arch is a natural arch in Arches National Park, Utah, United States. It is among the longest natural rock arches in the world.
The arch is among many in the Devils Garden area in the north of the park. Landscape Arch was named by Frank Beckwith who explored the area in the winter of 1933–1934 as the leader of an Arches National Monument scientific expedition. The arch can be reached by a 0.8 mi (1.3 km) graded gravel trail.
The Natural Arch and Bridge Society (NABS) considers Landscape Arch the fifth longest natural arch in the world, after four arches in China. In 2004, the span of Landscape Arch was measured at 290.1 ft (88.4 m), ±0.8 ft (0.24 m), with a height of 77.5 ft (23.6 m).
The most recent recorded rockfall events occurred in the 1990s when one large slab fell in 1991 and then two additional large rockfalls occurred in 1995. Since the rockfalls, the trail beneath the arch has been closed.
