Landscape Arch is a natural arch in Arches National Park, Utah, United States. It is among the longest natural rock arches in the world. [2]
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. [3] [4]
The Natural Arch and Bridge Society (NABS) considers Landscape Arch the fifth longest natural arch in the world, after four arches in China. [5] 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). [6] NABS measured the span of the slightly shorter Kolob Arch in Zion National Park at 287 ft (87 m) in 2006. [7]
The most recent recorded rockfall events occurred in the 1990s when one large slab fell in 1991 [3] [4] [8] and then two additional large rockfalls occurred in 1995. [3] Since the rockfalls, the trail beneath the arch has been closed. [3] [4]
A natural arch, natural bridge, or rock arch is a natural landform where an arch has formed with an opening underneath. Natural arches commonly form where inland cliffs, coastal cliffs, fins or stacks are subject to erosion from the sea, rivers or weathering.
Kolob Arch is a natural arch in Zion National Park, Utah, United States. According to the Natural Arch and Bridge Society (NABS), it is the sixth-longest natural arch in the world. In 2006, the Society measured the span at 287.4 ± 2 feet, which is slightly shorter than Landscape Arch in Arches National Park. Differences in measuring technique or definitions could produce slightly different results and change this ranking.
Natural Bridges National Monument is a U.S. National Monument located about 50 miles (80 km) northwest of the Four Corners boundary of southeast Utah, in the western United States, at the junction of White Canyon and Armstrong Canyon, part of the Colorado River drainage. It features the thirteenth largest natural bridge in the world, carved from the white Permian sandstone of the Cedar Mesa Formation that gives White Canyon its name.
Rainbow Bridge is a natural arch in southern Utah, United States. With a span of 275 feet (84 m), as reported in 1974 by the Bureau of Reclamation, and height of 290 feet (88 m), it is one of the largest natural arches in the world. At the top it is 42 feet (13 m) thick and 33 feet (10 m) wide. The bridge, which is of cultural importance to a number of area Native American tribes, has been designated a Traditional Cultural Property by the National Park Service. Rainbow Bridge National Monument was protected in 1910, and it is administered by Glen Canyon National Recreation Area.
Double Arch is a close-set pair of natural arches in Arches National Park in southern Grand County, Utah, United States, that is one of the more known features of the park.
Wrather Arch is a cave type natural arch in the Paria Canyon-Vermilion Cliffs Wilderness, in Coconino County, northern Arizona. The sandstone arch is located in the eponymous Wrather Canyon, a short side canyon of Paria Canyon. The Paria River is a tributary of the Colorado River, at its confluence down−canyon at Lee's Ferry. Wrather Arch was first spotted by a local pilot from Page, Arizona, Royce K Knight, as he flew over a remote gorge west of Glen Canyon. Reaching the arch by helicopter in 1963, Knight and National Geographic staff man Walter M Edwards calculated its height as 165 feet and about 250 feet across. A news bulletin from National Geographic dated February 4, 1966 states, "Tall as a 15 story building, Wrather Arch ... The Taj Mahal would fit comfortably into the arch..."
Aloba Arch is a natural arch located in Chad. Large natural arches are somewhat rare outside the southern and western regions of China and the Colorado Plateau of the southwest United States. Chad's Ennedi Plateau, located within the Sahara Desert in the northeast part of the country near Libya and Sudan has a geology similar to the Colorado Plateau and has produced a number of natural arches and similar landforms, although only Aloba can claim to be on the top ten list of longest arches in the world.
Sipapu Bridge is a natural bridge or arch located in the Natural Bridges National Monument in central San Juan County, Utah, United States. The bridge spans White Canyon.
State Route 128 (SR-128) is a 44.564-mile-long (71.719 km) state highway in the U.S. state of Utah. The entire length of the highway has been designated the Upper Colorado River Scenic Byway, as part of the Utah Scenic Byways program. This road also forms part of the Dinosaur Diamond Prehistoric Highway, a National Scenic Byway. Residents of Moab frequently refer to SR-128 as "the river road", after the Colorado River, which the highway follows.
Devils Garden is an area of Arches National Park, located near Moab, Utah, United States, that features a series of rock fins and arches formed by erosion. The Devils Garden Trail, including more primitive sections and spurs, meanders through the area for 7.2 mi (11.6 km). The trailhead leads directly to Landscape Arch after a 0.8 mi (1.3 km) outbound hike, while Tunnel Arch and Pine Tree Arch can be seen on spur trails on the way to Landscape Arch. Several other arches, including Partition, Navajo, Double O, and Private Arch, as well as the Dark Angel monolith and Fin Canyon, are accessed via the primitive loop trail and its spurs.
Coyote Gulch is a tributary of the Escalante River, located in Garfield and Kane Counties in southern Utah, in the western United States. Over 25 mi (40 km) long, Coyote Gulch exhibits many of the geologic features found in the Canyons of the Escalante, including high vertical canyon walls, narrow slot canyons, domes, arches, and natural bridges. The upper sections of Coyote Gulch are located within the Grand Staircase–Escalante National Monument, while its lower sections are located in the Glen Canyon National Recreation Area.
A catenary arch is a type of architectural arch that follows an inverted catenary curve. The catenary curve has been employed in buildings since ancient times. It forms an underlying principle to the overall system of vaults and buttresses in stone vaulted Gothic cathedrals and in Renaissance domes. It is not a parabolic arch.
Wall Arch was a natural sandstone arch in Arches National Park in southeastern Utah, United States. Before its collapse in 2008, it was ranked 12th in size among the park's over 2,000 arches. At its largest, the opening underneath the span was 71 feet (22 m) wide by 33.5 feet (10 m) high. It consisted of Entrada Sandstone, specifically the member known as Slick Rock. Wall Arch was first reported and named in 1948 by Lewis T. McKinney.
Arches National Park is a national park in eastern Utah, United States. The park is adjacent to the Colorado River, 4 mi (6 km) north of Moab, Utah. More than 2,000 natural sandstone arches are located in the park, including the well-known Delicate Arch, as well as a variety of unique geological resources and formations. The park contains the highest density of natural arches in the world.
Zion National Park is an American national park located in southwestern Utah near the town of Springdale. Located at the junction of the Colorado Plateau, Great Basin, and Mojave Desert regions, the park has a unique geography and a variety of life zones that allow for unusual plant and animal diversity. Numerous plant species as well as 289 species of birds, 75 mammals, and 32 reptiles inhabit the park's four life zones: desert, riparian, woodland, and coniferous forest. Zion National Park includes mountains, canyons, buttes, mesas, monoliths, rivers, slot canyons, and natural arches. The lowest point in the park is 3,666 ft (1,117 m) at Coalpits Wash and the highest peak is 8,726 ft (2,660 m) at Horse Ranch Mountain. A prominent feature of the 229-square-mile (590 km2) park is Zion Canyon, which is 15 miles (24 km) long and up to 2,640 ft (800 m) deep. The canyon walls are reddish and tan-colored Navajo Sandstone eroded by the North Fork of the Virgin River.
Xianren Bridge is a natural arch created by flowing water that has the world's longest recorded span. Carved of limestone karst, the formation bridges Buliu River in the northern Guangxi Zhuang Autonomous Region, China. Because of its remote location, accessible only by a three-hour rafting trip, it was not discovered until 2009 and remains relatively obscure. An expedition in October 2010 by the Natural Arch and Bridge Society first measured the bridge's span and found it to be 121.9 ± 4.6 m (400 ± 15 ft) in length.
The Devils Garden of the Grand Staircase–Escalante National Monument (GSENM) in south central Utah, United States, is a protected area featuring hoodoos, natural arches and other sandstone formations. The area is also known as the Devils Garden Outstanding Natural Area within the National Landscape Conservation System.
Blackwater Natural Bridge is a natural arch in Shoshone National Forest, Wyoming. The arch is located along a ridge at an elevation of 10,777 feet (3,285 m) and is a little over .50 mi (0.80 km) southwest of Coxcomb Mountain. Blackwater Natural Bridge is to the east of the headwaters of Blackwater Creek, which flows north to the North Fork Shoshone River. No official determination of the height or span of the arch has been completed and the estimated size of the arch varies greatly. The non-profit Natural Arch and Bridge Society states that the arch is anywhere from 70 to 100 feet while other sources claim that it may be one of the largest in the world, with a span of 240 ft (73 m), a height of 280 ft (85 m) and with rock thickness of the arch at 32 ft (9.8 m).
Bridge Mountain is a 6,803-foot (2,074 m) mountain made of Navajo Sandstone in Zion National Park in Washington County, of southwest Utah, United States.
