Caver
Caving – also known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland – is the recreational pastime of exploring wild cave systems (as distinguished from show caves). In contrast, speleology is the scientific study of caves and the cave environment.Caving in New Zealand (from Te Ara: The Encyclopedia of New Zealand, Accessed 2012-11.)

Cave Diving
Cave-diving is underwater diving in water-filled caves. It may be done as an extreme sport, a way of exploring flooded caves for scientific investigation, or for the search for and recovery of divers or, as in the 2018 Thai cave rescue, other cave users. The equipment used varies depending on the circumstances, and ranges from breath hold to surface supplied, but almost all cave-diving is done using scuba equipment, often in specialised configurations with redundancies such as sidemount or backmounted twinset. Recreational cave-diving is generally considered to be a type of technical diving due to the lack of a free surface during large parts of the dive, and often involves planned decompression stops. A distinction is made by recreational diver training agencies between cave-diving and cavern-diving, where cavern diving is deemed to be diving in those parts of a cave where the exit to open water can be seen by natural light. An arbitrary distance limit to the open water s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caving In New Zealand
Caving in New Zealand is an established hobby as well as being a part of commercial tourism. Recreational caving is practised by several hundred members of caving associations all over New Zealand, who take advantage of the widespread limestone karst cave systems present in the country, especially in the Waitomo District of the North Island and in the Nelson- Tasman region of the South Island. There are also several hundred thousands of visitors to various tourist caves in New Zealand per year,Caving tourism (from Te Ara: The Encyclopedia of New Zealand.

Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Vertical 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 Alps, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch (ascent/descent)
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. In climbing In advanced climbing or mountaineering, another definition of ''pitch'' is not restricted by the length of the rope.

Cave Survey
A cave survey is a map of all or part of a cave system, which may be produced to meet differing standards of accuracy depending on the cave conditions and equipment available underground. Cave surveying and cartography, i.e. the creation of an accurate, detailed map, is one of the most common technical activities undertaken within a cave and is a fundamental part of speleology. Surveys can be used to compare caves to each other by length, depth and volume, may reveal clues on speleogenesis, provide a spatial reference for other areas of scientific study and assist visitors with route-finding. Traditionally, cave surveys are produced in two-dimensional form due to the confines of print, but given the three-dimensional environment inside a cave, modern techniques using computer aided design are increasingly used to allow a more realistic representation of a cave system. History The first known plan of a cave dates from 1546, and was of a man-made cavern in tufa called the Stufe di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speleology
Speleology is the scientific study of caves and other karst features, as well as their make-up, structure, physical properties, history, life forms, and the processes by which they form (speleogenesis) and change over time (speleomorphology). The term ''speleology'' is also sometimes applied to the recreational activity of exploring caves, but this is more properly known as ''caving'', ''potholing'' (British English), or ''spelunking''. Speleology and caving are often connected, as the physical skills required for ''in situ'' study are the same. Speleology is a cross-disciplinary field that combines the knowledge of chemistry, biology, geology, physics, meteorology, and cartography to develop portraits of caves as complex, evolving systems. History Before modern speleology developed, John Beaumont wrote detailed descriptions of some Mendip caves in the 1680s. The term speleology was coined by Émile Rivière in 1890. Prior to the mid-nineteenth century the scientific valu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Show Cave
A show cave—also called tourist cave, public cave, and, in the United States, commercial cave—is a cave which has been made accessible to the public for guided visits. Definition A show cave is a cave that has been made accessible to the public for guided visits, where a cave is defined as a natural occurring void beneath the surface of the earth, per the International Show Caves Association. A show cave may be managed by a government or commercial organization and made accessible to the general public, usually for an entrance fee. Unlike wild caves, they may possess regular opening hours, guided group tours, constructed trails and stairs, color artificial illumination and other lighting, musical/video/laser shows and concerts, elevators, small trains, and boats if they contain underground water features. Some caves (mainly in Asia) open to the public have temples, monasteries and religious statues or monuments. Some caves are visited by millions of tourists annually ...

Clay Perry
Clair Willard Perry (1887–1961), called Clay Perry, was an American writer and outdoorsman. He coined the term " spelunker". Biography Born in 1887 in Waupaca, Wisconsin, Perry moved to western Massachusetts as a young man. A novelist, short story writer, and journalist, in the 1930s he worked for the Federal Writers' Project. He is best known as an amateur caver and as a writer on the caves of New England and the northeastern United States. He is credited with coining the term "spelunker" in the 1940s. He was also the author of a light verse on Israel Bissell, whose ride in April 1775 to warn the colonies of the Battles of Lexington and Concord was overshadowed in historical lore by that of Paul Revere. He died in 1961 in Pittsfield, Massachusetts Pittsfield is the largest city and the county seat of Berkshire County, Massachusetts, United States.

Cave Digging
Cave digging is the practice of enlarging undiscovered cave openings to allow entry. Cave digging usually follows a search of mountains and valleys in karst topography for new caves. Often it takes place underground in places where a large passage has clearly been backfilled with silt, or choked with boulders. Sometimes chisels or explosives can be used to widen constrictions in the passage when spaces are evident on the other side. Digs are in unstable parts of a cave and often need to be shored up with scaffolding or concrete to prevent re-collapse. It can be a dangerous activity, depending on the circumstances. Geological cave indicators Most of the obvious caves in countries with a well-established caving community have already been discovered and explored, so cavers must search for new caves. This is most commonly accomplished while ridgewalking, the practice of scouring the countryside, in areas with cave potential, for new, previously undiscovered openings to the under ...

British Caving Association
The British Caving Association (BCA) is the sports governing body for caving in the United Kingdom. It is recognised by UK Sport, Sport England and SportScotland. History The British Speleological Association (BSA) was founded in 1935, but this was not a national governing body. The National Caving Association (NCA) was established in 1968 as the first governing body, recognised by the Sports Council. However, the British Cave Research Association, the successor to the BSA, continued perform some 'national body' functions after its formation in 1973. The NCA existed until 2005 when it passed its responsibilities to the British Caving Association, which had been established the prior year. At the same time, the BCA also took over 'national body' functions from the British Cave Research Association. Structure The membership of the BCA is composed of Constituent Bodies, Regional Councils, clubs and individuals. The Constituent Bodies are: * Association of Caving Instruct ...
