Sipapu Bridge
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. Description Sipapu was long reported to have a span of by the National Park Service, ranking it as the fourth longest natural arch in the world. A more accurate measurement obtained by laser survey in 2007 revealed the measurement to be a significant overstatement. The Natural Arch and Bridge Society has published a revised span of , demoting the arch to a thirteenth-place ranking. Based on specific criteria that separate natural arches from natural bridges, Sipapu is the sixth longest natural bridge after the more well-known Rainbow Bridge also located in Utah, and four Chinese natural bridges—all longer than Rainbow Bridge—which were measured and documented by NABS between 2010 and 2015. Sipapu can be viewed from a roadside viewpoint, but more fully viewed from a short hiking trail that leads do ... [...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, Cliffed coast, coastal cliffs, Fin (geology), fins or Stack (geology), 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; h ...

Natural Bridges National Monument
Natural Bridges National Monument is a U.S. National Monument located about 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. The three bridges in the park are named ''Kachina'', ''Owachomo'', and ''Sipapu'' (the largest), which are all Hopi names. A natural bridge is formed through erosion by water flowing in the stream bed of the canyon. During periods of flash floods, particularly, the stream undercuts the walls of rock that separate the meanders (or "goosenecks") of the stream until the rock wall within the meander is undercut and the meander is cut off and the new stream bed then flows underneath the bridge. Eventually, as erosion and gravity enlarge the bridge's opening, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Juan County, Utah
San Juan County ( ) is a county in the southeastern portion of the U.S. state of Utah. As of the 2010 United States Census, the population was 14,746. Its county seat is Monticello, while its most populous city is Blanding. The Utah State Legislature named the county for the San Juan River, itself named by Spanish explorers (in honor of Saint John). San Juan County borders Arizona, Colorado, and New Mexico at the Four Corners. History The Utah Territory authorized creation of San Juan County on February 17, 1880, with territories annexed from Iron, Kane, and Piute counties. There has been no change in its boundaries since its creation. Monticello was founded in 1887, and by 1895 it was large enough to be designated the seat of San Juan County. Geography San Juan County lies in the southeastern corner of the state of Utah. Its borders coincide with the borders of the states of Colorado, New Mexico, and Arizona with Utah.

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.

White Canyon (San Juan County, Utah)
White Canyon is a canyon in San Juan County, Utah, United States. Description The canyon is notable for Ancestral Puebloan cliff dwellings and slot canyons. It is spanned by Sipapu Bridge, one of the largest natural bridges in the world. The canyon begins in the foothills of the Abajo Mountains and passes through Natural Bridges National Monument before emptying into Lake Powell. Utah State Route 95 parallels the inner gorge of the canyon for much of its length. One particularly deep and narrow section of White Canyon is known as the Black Hole. The walls in this permanently flooded long section are only a few feet (about 1 m) apart in some places. Canyoneers sometimes wear wetsuits to guard against hypothermia while traversing this section. The danger of flash flood A flash flood is a rapid flooding of low-lying areas: washes, rivers, dry lakes and depressions. It may be caused by heavy rain associated with a severe thunderstorm, hurricane, or trop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural Arch And Bridge Society
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Rainbow Bridge National Monument
Rainbow Bridge National Monument is administered by Glen Canyon National Recreation Area, southern Utah, United States. Rainbow Bridge is often described as the world's highest natural bridge. The span of Rainbow Bridge was reported in 1974 by the Bureau of Reclamation to be , but a measurement of span according to definition by the Natural Arch and Bridge Society in 2007 resulted in a value of . At the top it is thick and 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. Size Two other natural arches, Kolob Arch and Landscape Arch, both also in southern Utah, have confirmed spans several meters longer than Rainbow Bridge, but by most definitions of the terms they are considered to be arches rather than bridges. With a height of Rainbow Bridge does indeed stand taller than either of its longer competitors, but it is outdone by Aloba Arch in Chad ...

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. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
