Landscape Arch
Landscape Arch is the longest of the many natural rock arches located in Arches National Park, Utah, United States and among the longest natural stone arches in the world. Description 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 accessed by a 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. The span of Landscape Arch was measured at , ±, in 2004. NABS measured the span of the slightly shorter Kolob Arch in Zion National Park at in 2006. 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. See al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Utah
Utah ( , ) is a state in the Mountain West subregion of the Western United States. Utah is a landlocked U.S. state bordered to its east by Colorado, to its northeast by Wyoming, to its north by Idaho, to its south by Arizona, and to its west by Nevada. Utah also touches a corner of New Mexico in the southeast. Of the fifty U.S. states, Utah is the 13th-largest by area; with a population over three million, it is the 30th-most-populous and 11th-least-densely populated. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which is home to roughly two-thirds of the population and includes the capital city, Salt Lake City; and Washington County in the southwest, with more than 180,000 residents. Most of the western half of Utah lies in the Great Basin. Utah has been inhabited for thousands of years by various indigenous groups such as the ancient Puebloans, Navajo and Ute.

Moab, Utah
Moab () is the largest city and county seat of Grand County in eastern Utah in the western United States, known for its dramatic scenery. The population was 5,366 at the 2020 census. Moab attracts many tourists annually, mostly visitors to the nearby Arches and Canyonlands National Parks. The town is a popular base for mountain bikers who ride the extensive network of trails including the Slickrock Trail, and for off-roaders who come for the annual Moab Jeep Safari. History Early years The Biblical name Moab refers to an area of land located on the eastern side of the Jordan River. Some historians believe the city in Utah came to use this name because of William Andrew Peirce, the first postmaster, believing that the biblical Moab and this part of Utah were both "the far country". However, others believe the name has Paiute origins, referring to the word ''moapa'', meaning "mosquito". Some of the area's early residents attempted to change the city's name, because in the Chr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Arch
A natural arch, natural bridge, or (less commonly) 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 ( subaerial processes). Most natural arches are formed from narrow fins and sea stacks composed of sandstone or limestone with steep, often vertical, cliff faces. The formations become narrower due to erosion over geologic time scales. The softer rock stratum erodes away creating rock shelters, or alcoves, on opposite sides of the formation beneath the relatively harder stratum, or caprock, above it. The alcoves erode further into the formation eventually meeting underneath the harder caprock layer, thus creating an arch. The erosional processes exploit weaknesses in the softer rock layers making cracks larger and removing material more quickly than the caprock; however, the caprock itself continues to er ...

Devils Garden (Arches National Park)
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 . The trailhead leads directly to Landscape Arch after a 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. Wall Arch, before its collapse in 2008, was also located in Devils Garden just north of Landscape Arch. Black Arch is visible as a dark outline from the primitive trail and can be approached via an unmarked sidetrack. The trailhead for Devils Garden is located at the end of the main park road. A campground and amphitheater are also available at the site. History In the early 1920s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Durdle Door
Durdle Door (sometimes written Durdle Dor) is a natural limestone arch on the Jurassic Coast near Lulworth in Dorset, England.West, I.W., 2003.Durdle Door; Geology of the Dorset Coast. Southampton University, UK. Version H.07.09.03. It is privately owned by the Weld Family who own the Lulworth Estate, but it is also open to the public. Geology The form of the coastline around Durdle Door is controlled by its geology—both by the contrasting hardnesses of the rocks, and by the local patterns of faults and folds.Nowell, D. A. G. "The geology of Lulworth Cove, Dorset." Geology Today 14 (1998): 71–74. The arch has formed on a concordant coastline where bands of rock run parallel to the shoreline. The rock strata are almost vertical, and the bands of rock are quite narrow. Originally a band of resistant Portland limestone ran along the shore, the same band that appears one mile along the coast forming the narrow entrance to Lulworth Cove. Behind this is a band of weaker, easi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wall 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 wide by 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. Wall Arch collapsed some time between the night of August 4 and the morning of August 5, 2008, temporarily blocking Devils Garden Trail. No one observed the fall. It was the first collapse of a major arch in the park since sections of Landscape Arch fell in 1991.
