Lamb Leer
Lamb Leer () is a 14.59 hectare (36.04 acre) geological Site of Special Scientific Interest between East Harptree and Priddy in the Mendip Hills, Somerset, notified in 1983. The cavern is a fragment of a very ancient major cave system which now contains one of the largest chambers in the Mendip Hills. History Several explanations have been suggested for the origin of the name. One links to an old name for the area which was "Lambden". An alternative suggestion is that in the 1670s miners spoke of ''"leirey places, that is cavernous"'' which links to the German word "leer" which means void and may have been introduced by German miners. A more likely explanation is from the Anglo-Saxon word "lear" meaning empty or void. Lamb Leer Cavern was first found by miners looking for lead around 1676, and in 1681, the geologist John Beaumont, the pioneer of pit caving, gave an account of his descent into the cave to the Royal Society. It was rediscovered in 1880, when a new shaft was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Harptree
West Harptree is a small village and civil parish in the Chew Valley, Somerset within the unitary district of Bath and North East Somerset. The parish has a population of 439. The village is south of Bristol, southwest of Bath and east of Weston-super-Mare. It is just south of Chew Valley Lake on the A368 between Bishop Sutton and Compton Martin. The village has a pub and several shops including a post office. With its close neighbour East Harptree the villages are collectively known as the Harptrees. History According to Stephen Robinson it is listed in the 1086 Domesday Book as ''Herpetreu'' meaning 'The military road by the wood' from the Old English ''herepoep'' and ''treow''. Between 1154 and 1172 an estate at West Harptree was granted by William FitzJohn to the Knights Templar. The shape of some of the existing fields with cross-slope and down-slope field banks and cultivated ridges forming an interleaving irregular mosaic suggest they are of medieval origin. ...

Pit Cave
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] |
Limestone Caves
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limestone co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caves Of The Mendip Hills
The caves of the Mendip Hills are formed by the particular geology of the Mendip Hills: large areas of limestone worn away by water makes it a national centre for caving. The hills conceal the largest underground river system in Britain. Geology The hills consist of anticlines of Carboniferous Limestone lying over Devonian Old Red Sandstone, with the sandstone exposed on the summits. When a surface stream running off the sandstone reaches the limestone it sinks below ground through a " swallet", (also known locally as a "slocker"), continuing on its way down towards sea level by enlarging existing cracks in the rock to form caves, and reappearing at the base of the limestone outcrop. As the water changes route within the hill some caves (or parts of caves) are left dry. There is a characteristic type of Mendip cave, in which there is an initially steep descent, and then a more level stretch ending in a "sump" as the cave reaches and descends below the prevailing water table.

Stalagmite
A stalagmite (, ; from the Greek , from , "dropping, trickling") is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats). The corresponding formation hanging down from the ceiling of a cave is a stalactite. Mnemonics have been developed for which word refers to which type of formation; one is that ''stalactite'' has a C for "ceiling", and ''stalagmite'' has a G for "ground", another is that, as with ants in the pants, the mites go up and the tights (tites) come down. Formation and type Limestone stalagmites The most common stalagmites are speleothems, which usually form in limestone caves. Stalagmite formation occurs only under certain pH conditions within the cavern. They form through deposition of calcium carbonate ...

Geologists
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists. Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate chan ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Aerial Lift
An aerial lift, also known as a cable car or ropeway, is a means of cable transport in which ''cabins'', ''cars'', ''gondolas'', or open chairs are hauled above the ground by means of one or more cables. Aerial lift systems are frequently employed in a mountainous territory where roads are relatively difficult to build and use, and have seen extensive use in mining. Aerial lift systems are relatively easy to move and have been used to cross rivers and ravines. In more recent times, the cost-effectiveness and flexibility of aerial lifts have seen an increase of gondola lift being integrated into urban public transport systems. Types Cable Car A cable car (British English) or an aerial tramway, aerial tram (American English), uses one or two stationary ropes for support while a separate moving rope provides propulsion. The grip of an aerial tramway is permanently fixed onto the propulsion rope. Aerial trams used for urban transport include the Roosevelt Island Tramway ( New Yor ...

John Beaumont (geologist)
John Beaumont (c. 1650–1731) was an English physician and early geologist. Biography John Beaumont was a physician who lived in Ston Easton in Somerset. He was encouraged by Robert Hooke to study the natural history of Somerset but became more interested in witchcraft. He married Dorothy, daughter of John Speccott of Penheale, Egloskerry, Cornwall Geology John Beaumont sent four letters to the Royal Society, two in 1676, one in 1681 and another in 1683. The topics he touched upon included rock plants, ailments afflicting both cattle and miners, detailed descriptions of some Mendip caves, including Wookey Hole Caves and Lamb Leer Cavern. He was elected a Fellow of the society in May 1685. Experience of spirits I had two spirits, who constantly attended me, night and day, for above three months together, who called each other by their names; and several spirits would call at my chamber door, and ask whether such spirits lived there, and they would answer they did.
