List Of Longest Natural Arches
This list of longest natural arches ranks the world's natural arches by the length of their span as defined and measured by the Natural Arch and Bridge Society (NABS). As a disclaimer, the NABS states that the information in this list, and therefore the rankings, may change due to more accurate measurements in the future, changes in span length due to natural forces, and the discovery of previously undocumented arches. Longest natural arches All known natural arches with span lengths of or greater are included in the list. Sort by clicking on column headings, excepting only the ''Image'' and ''Notes'' columns.

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 ...

Kolob Arch 3a
Kolob is a star or planet described in the Book of Abraham, a sacred text of the Latter Day Saint movement. Several Latter Day Saint denominations hold the Book of Abraham to have been translated from an Egyptian papyrus scroll by Joseph Smith, the founder of the movement. According to this work, Kolob is the heavenly body nearest to the throne of God. While the Book of Abraham calls Kolob a "star", it also calls planets "stars", (noting "Confusion between the uses of the terms stars and planets"). and therefore some Latter Day Saint commentators consider Kolob a planet. The body also appears in Latter Day Saint culture, including a reference to Kolob in an LDS hymn. Doctrine and exegesis Description in the Book of Abraham The first published reference to Kolob is in the Book of Abraham, first published in 1842 in ''Times and Seasons'' and now included within the Pearl of Great Price as part of the canon of Mormonism. The Book of Abraham 1:1–2:18 were dictated in 1835 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ennedi Plateau
The Ennedi Plateau is located in the northeast of Chad, in the regions of Ennedi-Ouest and Ennedi-Est. It is considered a part of the group of mountains known as the Ennedi Massif found in Chad, which is one of the nine countries that make up the Sahelian belt that spans the Atlantic Ocean to Sudan. The Ennedi is a sandstone bulwark in the middle of the Sahara, which was formed by erosion from wind and temperature. Many people occupied this area, such as hunters and gatherers (5,000-4,000 cal BC) and pastoralists (beginning 4,000 cal BC). The Ennedi area is also known for its large collection of rock art depicting mainly cattle, as these animals were the main source of financial, environmental, and cultural impact. This art dates back nearly 7,000 years ago. Today, two semi-nomadic groups, mainly of the Muslim religion, have permanent villages in the Ennedi during the rainy months and pass through the area during the dry season. They rely on their herds of camels, donkeys, sheep, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aloba Arch
Aloba Arch is the name of 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. Aloba Arch's span is considered to be the 8th longest known natural arch, and the longest outside of China and Utah. Due in part to its location as well as being only recently recognized for its size, estimates based on photography yield an approximate span of .
