Caving Techniques
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.) The challenges involved in caving vary according to the cave being visited; in addition to the total absence of light beyond the entrance, negotiating pitches, squeezes, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Utilities
A public utility company (usually just utility) is an organization that maintains the infrastructure for a public service (often also providing a service using that infrastructure). Public utilities are subject to forms of public control and regulation ranging from local community-based groups to statewide government monopolies. Public utilities are meant to supply goods/services that are considered essential; water, gas, electricity, telephone, and other communication systems represent much of the public utility market. The transmission lines used in the transportation of electricity, or natural gas pipelines, have natural monopoly characteristics. If the infrastructure already exists in a given area, minimal benefit is gained through competing. In other words, these industries are characterized by ''economies of scale'' in production. There are many different types of public utilities. Some, especially large companies, offer multiple products, such as electricity and natu ...

Outdoor Activity
Outdoor recreation or outdoor activity refers to recreation done outside, most commonly in natural settings. The activities that encompass outdoor recreation vary depending on the physical environment they are being carried out in. These activities can include fishing, hunting, backpacking, and horseback riding — and can be completed individually or collectively. Outdoor recreation is a broad concept that encompasses a varying range of activities and landscapes. Outdoor recreation is typically pursued for purposes of physical exercise, general wellbeing, and spiritual renewal. While a wide variety of outdoor recreational activities can be classified as sports, they do not all demand that a participant be an athlete. Rather, it is the collectivist idea that is at the fore in outdoor recreation, as outdoor recreation does not necessarily encompass the same degree of competitiveness or rivalry that is embodied in sporting matches or championships. Competition generally is less ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

New England
New England is a region comprising six states in the Northeastern United States: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. It is bordered by the state of New York to the west and by the Canadian provinces of New Brunswick to the northeast and Quebec to the north. The Atlantic Ocean is to the east and southeast, and Long Island Sound is to the southwest. Boston is New England's largest city, as well as the capital of Massachusetts. Greater Boston is the largest metropolitan area, with nearly a third of New England's population; this area includes Worcester, Massachusetts (the second-largest city in New England), Manchester, New Hampshire (the largest city in New Hampshire), and Providence, Rhode Island (the capital of and largest city in Rhode Island). In 1620, the Pilgrims, Puritan Separatists from England, established Plymouth Colony, the second successful English settlement in America, following the Jamestown Settlement in Virginia foun ...

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.

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] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Cueva Del Viento
Cueva del Viento ("Wind Cave") is the largest lava tube system in Europe, and the sixth largest in the world, behind a series of lava tubes in Hawaii. It is also considered the most complex volcanic tube in the world, due to its morphology of several levels and passages. It was created by lava flows from Pico Viejo, next to Mount Teide. The cave is located in the town of Icod de los Vinos in the north of the island of Tenerife, Spain. It extends more than and contains three different levels of passageways, each full of geomorphological phenomena such as lava pits and terraces. The cave is rich in fossils of the " Canarian megafauna". Bones of ''Gallotia goliath'' and ''Canariomys bravoi'', an extinct giant lizard and rat, respectively, have been discovered here. Archaeological remains belonging to the Guanches, the ancient Berber native inhabitants of the Canary Islands, were found in several entries to the tube system. At present, the Cueva del Viento is a tourist attractio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava River Cave
The Lava River Cave near Bend, Oregon, is part of the Newberry National Volcanic Monument, which is managed by the United States Forest Service. At in length, the northwest section of the cave is the longest continuous lava tube in Oregon. While the cave's discovery in 1889 was officially credited to a pioneer hunter, the presence of obsidian flakes near the cave has led archaeologists to conclude that Native Americans knew about the cave long before settlers arrived in central Oregon. Geology The eruption which formed the Lava River Cave occurred about 80,000 years ago. The source is believed to be near Mokst Butte southeast of the entrance. The same volcanic flow that formed the cave underlies much of the Bend area and almost reaches Redmond, Oregon. However, the specific vent that created the cave has been buried by several younger flows. [...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 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 ...
