Long Kin East Cave - Rift Pot System
The Long Kin East Cave - Rift Pot system is a limestone cave system on the southern flanks of Ingleborough, North Yorkshire in England lying within the designated Ingleborough Site of Special Scientific Interest. Long Kin East Cave starts as a long meandering stream passage but then plummets down a deep shaft when it meets a shattered fault into which Rift Pot also descends. At the bottom, the stream flows through some low canals and sumps, to eventually emerge at Austwick Beck Head in Crummackdale. Description The main entrance to Long Kin East Cave () is where a small stream sinks into a deepening fissure in a small exposure of limestone rocks located in an extensive area of moorland. The fissure gains a roof and morphs into a walking-sized meandering stream passage, passing an alternative dry entrance at the first corner. After the passage passes below a walled-off pothole () where daylight enters. After a further an ascent up a slope of rocks leads to the bottom of the ...

Ingleborough
Ingleborough () is the second-highest mountain in the Yorkshire Dales, England. It is one of the Yorkshire Three Peaks (the other two being Whernside and Pen-y-ghent), and is frequently climbed as part of the Three Peaks walk. A large part of Ingleborough is designated as a Site of Special Scientific Interest and National Nature Reserve and is the home of a new joint project, Wild Ingleborough, with aims to improve the landscape for wildlife and people. Name The first element of the name "Ingleborough" has been variably explained as a Scots term for 'beacon, fire', an Old Danish term meaning 'English' or a derivative of Old English ''ing'', 'peak'. The second element is derived from the Old English word '' burh'', meaning "a fortified place"; in this case, a hill fort. The summit plateau of Ingleborough is encircled by the remains of a massive stone rampart, containing the foundations of Iron Age huts. Geography Ingleborough is in the south-western corner of the Yo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vadose Zone
The vadose zone, also termed the unsaturated zone, is the part of Earth between the land surface and the top of the phreatic zone, the position at which the groundwater (the water in the soil's pores) is at atmospheric pressure ("vadose" is from the Latin word for "shallow"). Hence, the vadose zone extends from the top of the ground surface to the water table. Water in the vadose zone has a pressure head less than atmospheric pressure, and is retained by a combination of adhesion (''funiculary groundwater''), and capillary action (''capillary groundwater''). If the vadose zone envelops soil, the water contained therein is termed soil moisture. In fine grained soils, capillary action can cause the pores of the soil to be fully saturated above the water table at a pressure less than atmospheric. The vadose zone does not include the area that is still saturated above the water table, often referred to as the capillary fringe. Freeze, R.A. and Cherry, J.A., 1979. Groundwater. Engle ...

Rick Stanton
Richard William Stanton, (born 1961) is a British civilian cave diver who specialises in rescues through the Cave Rescue Organisation and the British Cave Rescue Council. He has been called "one of the world's most accomplished cave-divers", "the face of British cave diving," and "the best cave diver in Europe". Stanton has lived in Coventry for many years, and was formerly a firefighter with the West Midlands Fire Service for 25 years prior to his retirement. In 2018 he played a leading role in the Tham Luang cave rescue and was awarded the George Medal in the Civilian Gallantry List. Early life Stanton was born in 1961 and grew up in Epping Forest District in Essex. He attributes his interest in cave diving to a television programme he watched as a teenager, ''The Underground Eiger'', saying, "After watching it, I just knew that cave-diving was for me." Stanton studied at Aston University, where he joined both the caving and the diving clubs. He began as a self-taug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eli Simpson
Eli "Cymmie" Simpson ( – ) was an influential and controversial British caver and speleologist, and a founding member and Recorder of the British Speleological Association. Life and career Simpson began caving in 1901, and in 1905 helped create the Yorkshire Speleological Association, the first British club formed specifically for the purposes of exploring caves. Simpson undertook cave exploration, mapping, and photography throughout his active career. Simpson was a founding member of the British Speleological Association in 1935, became its Recorder for much of its existence, and organized the most extensive cave archive in Britain. The installation of gates on BSA-controlled caves caused much friction with other caving organizations as well as within the BSA. BSA influence waned after 1945 when new or dormant caving clubs (such as Northern Pennine Club and Red Rose Cave and Pothole Club) gained ground, and members expelled or resigned from the BSA went on to create o ...

Yorkshire Ramblers Club
The Yorkshire Ramblers' Club (YRC) is the second-oldest mountaineering club in England, the oldest being the Alpine Club. Founded in 1892, the YRC is still a highly active club mountaineering and caving in the UK and all over the world. History On 13 July 1892 four Yorkshire gentlemen met at the home of a Mr. Herbert Slater in Leeds to discuss the idea of forming a club for individuals interested in promoting the idea of walking and the study of the countryside. At an open meeting held at the Skyrack Inn, Headingley on 6 October 1892 it was unanimously decided to form a club to organise walking and mountaineering expeditions and encourage the study of nature. The name of the club was picked from others including The Three Peaks Club, but Yorkshire understatement prevailed and the name Yorkshire Ramblers' Club was chosen. Consequently, "greater attention was paid to climbing the Lake District", in both the club's earliest days and today with the adjoining Scottish Borders als ...

Yorkshire Geological Society
The Yorkshire Geological Society is a learned, professional and educational charity devoted to the earth sciences, founded in 1837. Its work is centred on the geology of Yorkshire, and the north of England more generally, ranging from Northumbria and Cumbria in the north to Nottinghamshire, Derbyshire and Leicestershire in the south. The Society has around 600 members, the majority living within this region but with significant proportions of UK national and overseas members. It also has working relationships with around 20 Corresponding Societies and other affiliated local geological and conservation societies and organisations, and with many of the universities of the region, as well as with the British Geological Survey, particularly its headquarters at Keyworth, Nottinghamshire. The Society runs a wide-ranging programme of both indoor and field meetings for members, public lectures and conferences in various locations across its region, and coordinates and promotes with the ...

Fluorescein
Fluorescein is an organic compound and dye based on the xanthene tricyclic structural motif, formally belonging to triarylmethine dyes family. It is available as a dark orange/red powder slightly soluble in water and alcohol. It is widely used as a fluorescent tracer for many applications. The color of its aqueous solutions is green by reflection and orange by transmission (its spectral properties are dependent on pH of the solution), as can be noticed in bubble levels, for example, in which fluorescein is added as a colorant to the alcohol filling the tube in order to increase the visibility of the air bubble contained within (thus enhancing the precision of the instrument). More concentrated solutions of fluorescein can even appear red (because under these conditions nearly all incident emission is re-absorbed by the solution). It is on the World Health Organization's List of Essential Medicines. Uses Fluorescein sodium, the sodium salt of fluorescein, is used extens ...

The Gentleman's Magazine
''The Gentleman's Magazine'' was a monthly magazine founded in London, England, by Edward Cave in January 1731. It ran uninterrupted for almost 200 years, until 1922. It was the first to use the term '' magazine'' (from the French ''magazine'', meaning "storehouse") for a periodical. Samuel Johnson's first regular employment as a writer was with ''The Gentleman's Magazine''. History The original complete title was ''The Gentleman's Magazine: or, Trader's monthly intelligencer''. Cave's innovation was to create a monthly digest of news and commentary on any topic the educated public might be interested in, from commodity prices to Latin poetry. It carried original content from a stable of regular contributors, as well as extensive quotations and extracts from other periodicals and books. Cave, who edited ''The Gentleman's Magazine'' under the pen name "Sylvanus Urban", was the first to use the term '' magazine'' (meaning "storehouse") for a periodical. Contributions to the ma ...

Phreatic
''Phreatic'' is a term used in hydrology to refer to aquifers, in speleology to refer to cave passages, and in volcanology to refer to a type of volcanic eruption. Hydrology The term phreatic (the word originates from the Greek , meaning "well" or "spring") is used in hydrology and the earth sciences to refer to matters relating to ground water (an aquifer) below the water table. The term 'phreatic surface' indicates the location where the pore water pressure is under atmospheric conditions (i.e. the pressure head is zero). This surface normally coincides with the water table. The slope of the phreatic surface is assumed to indicate the direction of ground water movement in an unconfined aquifer. The phreatic zone, below the phreatic surface where rock and soil is saturated with water, is the counterpart of the vadose zone, or unsaturated zone, above. Unconfined aquifers are also referred to as phreatic aquifers because their upper boundary is provided by the phreatic surf ...

Shear Zone
In geology, a shear zone is a thin zone within the Earth's crust or upper mantle that has been strongly deformed, due to the walls of rock on either side of the zone slipping past each other. In the upper crust, where rock is brittle, the shear zone takes the form of a fracture called a fault. In the lower crust and mantle, the extreme conditions of pressure and temperature make the rock ductile. That is, the rock is capable of slowly deforming without fracture, like hot metal being worked by a blacksmith. Here the shear zone is a wider zone, in which the ductile rock has slowly flowed to accommodate the relative motion of the rock walls on either side. Because shear zones are found across a wide depth-range, a great variety of different rock types with their characteristic structures are associated with shear zones. General introduction A shear zone is a zone of strong deformation (with a high strain rate) surrounded by rocks with a lower state of finite strain. It i ...

Fault Breccia
Fault breccia ( or ; Italian for "breach"), or tectonic breccia, is a breccia (a rock type consisting of angular clasts) that was formed by tectonic forces. Fault breccia is a tectonite formed by localized zone of brittle deformation (a fault zone) in a rock. Brecciation in fault zones influences fault zone hydrogeology in its interaction with groundwater and petroleum deposits. Origin Fault breccias are tectonites formed primarily by tectonic movement along a localized zone of brittle deformation (a fault zone) in a rock formation or province. The grinding and milling occurring when the two sides of the fault zone moving along each other results in a material that is made of loose fragments. Because of this fragmentation fault zones are easily infiltrated by groundwater. Secondary minerals such as calcite, epidote, quartz or talc can precipitate from the circulating groundwater filling the voids and cementing the rock. However, when the tectonic movement along the fault zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dip (geology)
Strike and dip is a measurement convention used to describe the orientation, or attitude, of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination measured downward from horizontal. They are used together to measure and document a structure's characteristics for study or for use on a geologic map. A feature's orientation can also be represented by dip and dip direction, using the azimuth of the dip rather than the strike value. Linear features are similarly measured with trend and plunge, where "trend" is analogous to dip direction and "plunge" is the dip angle. Strike and dip are measured using a compass and a clinometer. A compass is used to measure the feature's strike by holding the compass horizontally against the feature. A clinometer measures the features dip by recording the inclination perpendicular to the strike. These can be done separately, or together using a tool such as ...
