Pothole (caving)
A pit cave, shaft cave or vertical cave—or often simply called a pit (in the US) and pothole or pot (in the UK); jama in South Slavic languages scientific and colloquial vocabulary (borrowed since early research in the Western Balkan Dinaric Alpine karst)—is a type of cave which contains one or more significant vertical shafts rather than being predominantly a conventional horizontal cave passage. Pit caves typically form in limestone as a result of long-term erosion by water. They can be open to the surface or found deep within horizontal caves. Among cavers, a pit is a vertical drop of any depth that cannot be negotiated safely without the use of ropes or ladders. Pit caving Techniques Exploration into pit caves ("vertical caving", also called "potholing" in the UK and "pit caving" in US English) requires the use of equipment such as nylon kernmantle rope or cable ladders. The specialized caving techniques of single rope technique (SRT) is common practice and the preferre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gaping Gill
Gaping Gill (also known as Gaping Ghyll) is a natural cave in North Yorkshire, England. It is one of the unmistakable landmarks on the southern slopes of Ingleborough – a deep pothole with the stream Fell Beck flowing into it. After falling through one of the largest known underground chambers in Britain, the water disappears into the bouldery floor and eventually resurges adjacent to Ingleborough Cave. The shaft was the deepest known in Britain, until Titan in Derbyshire was discovered in 1999. Gaping Gill still retains the records for the highest unbroken waterfall in England and the largest underground chamber naturally open to the surface. Features Due to the number of entrances which connect into the cave, many different routes through and around the system are possible. Other entrances include Jib Tunnel, Disappointment Pot, Stream Passage Pot, Bar Pot, Hensler's Pot, Corky's Pot, Rat Hole, and Flood Entrance Pot. The Bradford Pothole Club around Whit ...

Slovenia
Slovenia ( ; sl, Slovenija ), officially the Republic of Slovenia (Slovene: , abbr.: ''RS''), is a country in Central Europe. It is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the southeast, and the Adriatic Sea to the southwest. Slovenia is mostly mountainous and forested, covers , and has a population of 2.1 million (2,108,708 people). Slovenes constitute over 80% of the country's population. Slovene, a South Slavic language, is the official language. Slovenia has a predominantly temperate continental climate, with the exception of the Slovene Littoral and the Julian Alps. A sub-mediterranean climate reaches to the northern extensions of the Dinaric Alps that traverse the country in a northwest–southeast direction. The Julian Alps in the northwest have an alpine climate. Toward the northeastern Pannonian Basin, a continental climate is more pronounced.

Pitch (vertical Space)
In rock climbing and ice climbing, a pitch is a steep section of a route that requires a rope between two belays, as part of a climbing system. Standard climbing ropes are between 50 and 80 metres long, so a pitch is always shorter, between two convenient ledges if possible; longer routes are multi-pitch, requiring the re-use of the rope each time. In free climbing, pitch refers to classification by climbers of the difficulty of ascent on certain climbing routes. illustrated superimposed on the successful ascent of the Dawn Wall, as photographed on El Capitan in Yosemite.

Rappel Rack
Abseiling ( ; ), also known as rappelling ( ; ), is the controlled descent of a steep slope, such as a rock face, by moving down a rope. When abseiling the person descending controls their own movement down the rope, in contrast to lowering off in which the rope attached to the person descending is paid out by their belayer. This technique is used by climbers, mountaineers, cavers, canyoners, search and rescue and rope access technicians to descend cliffs or slopes when they are too steep and/or dangerous to descend without protection. Many climbers use this technique to protect established anchors from damage. Rope access technicians also use this as a method to access difficult-to-reach areas from above for various industrial applications like maintenance, construction, inspection and welding. To descend safely, abseilers use a variety of techniques to increase the friction on the rope to the point where it can be controlled comfortably. These techniques range f ...

Petzl
Petzl is a French manufacturer of climbing gear, caving gear, work-at-height equipment, and headlamps based in Crolles (near Grenoble), France. The company was created by the cave explorer Fernand Petzl in the mid-1970s. Their three specialties are: *Vertical sports: equipment for mountaineering, climbing, caving, etc. *Work at height and rescue: solutions for progression and safety in difficult-access worksites and in technical rescue. *Headlamps/head torches that provide hands free lighting. History Fernand Petzl, born in 1912, began his caving career in the late 1920s and early 1930s. In 1936, Petzl was introduced to, then small-time caver, Pierre Chevalier. The two began work on improving the technology behind their sport. In 1943, Chevalier designed and tested the first nylon rope to replace caving ladders. This technology provided the foundation for nearly all vertical safety methods to come. Chevalier's innovation led to the first 1,000 meter cave descent when Petzl e ...

Petzl Croll
A Petzl Croll is an ascending device used in caving and industrial rope access made by the French company Petzl. Its name comes from the town Crolles where Petzl's company headquarters are located but might also be a reference to the nearby cave system of the Dent de Crolles, the exploration of which triggered a lot of technical effort leading to innovation in caving equipment. Usage The Croll is normally used in the chest position and in conjunction with an upper ascender or Jumar. This configuration allows a climber, caver or rope access worker to rapidly ascend a rope. History In 1968 Bruno Dressler asked Fernand Petzl, who worked as a metals machinist, to build a rope-ascending tool, today known as the Petzl Croll, that he had developed by adapting the Jumar to the specificity of pit caving. Following these developments, Fernand Petzl started in the 1970s a small caving equipment manufacturing company Petzl Petzl is a French manufacturer of climbing gear, caving gear, ...

Jumar
An ascender is a device (usually mechanical) used for directly ascending a rope, or for facilitating protection with a fixed rope when climbing on very steep mountain terrain. Ascenders can also be used as a braking component within a rope hauling system, often used in rescue situations. Use Ascenders are usually used in pairs, and offer similar functionality to friction knots, but are faster, safer and easier to use, albeit still with consequences in weight and in security (as ascenders can, even with a locking carabiner, come off the rope, and fail by shredding the rope at high loads, rather than slipping and fusing as with friction knots). A mechanical ascender employs a cam which allows the device to slide freely in the intended direction of movement, but provide a firm grip on the rope when pulled in the opposite direction. To prevent an ascender from accidentally coming off the rope, a locking mechanism or trigger is deployed. The ascender is first attached to the cl ...

Dent De Crolles
The Dent de Crolles () is a karstic mountain (2,062 m) of the Chartreuse Mountains range, north east of Grenoble, Isère, France. It has a characteristic "tooth-like" profile and is easily recognizable in the Isère Valley (Grésivaudan) in the Grenoble area. The French word "dent" means tooth and "de Crolles" is derived from the town of Crolles, located next to the mountain.

Fernand Petzl
Fernand Petzl (April 7, 1913 – May 31, 2003) was a caver and manufacturer of outdoor equipment under the brand name Petzl. Petzl lived most of his life in the village of Saint-Ismier (near Grenoble), France at the foot of the mountain Dent De Crolles. He first went caving in Trou du Glaz in 1933, and was immediately captivated by the idea of exploring beyond the cave's known limits. Subsequent explorations there with Pierre Chevalier, Charles Petit-Didier and others culminated in connections to other caves in the massif, forming the Réseau de la Dent de Crolles which, in 1947, became the deepest cave in the world. Petzl also participated in explorations in the Gouffre Berger The Gouffre Berger is a French cave discovered on 24 May 1953 by Joseph Berger, Bouvet, Ruiz de Arcaute and Marc Jouffrey. From 1953 to 1963, it was regarded as the deepest cave in the world at , relinquishing this title to the previous contender, ..., which set a new world depth record in 1956 as the f ...
