Death's Head Hole
Death's Head Hole is a cave on Leck Fell, in Lancashire, England. Its entrance is a deep shaft. It leads into Lost Johns' Cave and is part of the Three Counties System, an cave system which spans the borders of Cumbria, Lancashire, and North Yorkshire. Description The fenced entrance shaft descends some onto a loose boulder slope which leads to a second pitch of into the Main Chamber, a large chamber with a waterfall entering at the east end. An excavated deep scaffolded shaft in the bottom corner of the chamber soon leads into a stream passage some long which ends at a waterfall into the main Lost Johns' Master Cave about from its terminal sump. A climb up the waterfall in the Main Chamber enters East Passage, a well decorated phreatic passage with a misfit stream. It passes under an aven, and eventually lowers to a silted crawl after . The aven has been climbed for to a choked inlet. The stream enters East Passage from a low crawl after , called Dolphin Passage. Thi ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

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 Three Counties System
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 ...

Caving In The United Kingdom
Recreational caving in the United Kingdom dates back to the mid-19th century. The four major caving areas of the United Kingdom are North Yorkshire, South Wales, Derbyshire, and the Mendips. Minor areas include Devon, North Wales, and the Scottish Highlands. Caving grew in popularity in the 1950s and 60s through participation in caving clubs. There are about 4,000 active cavers in the UK and nearly twenty times that number who attend instructor-led courses each year in caves around the country. In addition, many tourists visit show caves such as Wookey Hole Caves. Cave diving is a niche technical area of caving practised in the UK since the 1930s. This skill enables cavers to explore water-filled cave passages in Britain, and around the world. In recent years, British cave divers have been called on internationally for cave rescues and recoveries. History Before modern caving developed, John Beaumont wrote detailed descriptions of some Mendip caves in 1681, and in 1780 Jo ...

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 a ...

A Caver Descending Death's Heads Hole Entrance Shaft
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it f ...

Leck Beck
Leck Beck is a watercourse in Lancashire with its source on Crag Hill in Cumbria between Leck Fell and Casterton Fell. For several kilometres near the start of its course, the water flows into the Ease Gill Cave System, part of The Three Counties System, the longest cave system in Britain (and 26th longest in the world) via 14 major sink holes, to resurge at a major spring at Leck Beck Head. The rising of Leck Beck Head was dived extensively in the 1980s and required underwater digging and the use of an air chisel to make progress. The overflow for this rising, Witches Cave (Yorkshire), has been dived through a 300m sump into Witches II. A dry entrance was dug into Witches II from the surface in 2010. The Beck flows through Leck, Cowan Bridge and Overtown before joining the River Lune near Nether Burrow Nether Burrow is a small hamlet in the Lunesdale Valley of North Lancashire, England. It is a small settlement on the banks of the River Lune. There is not much the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rumbling Hole
Rumbling Hole is a cave on Leck Fell, in Lancashire, England. Its entrance is a deep fenced shaft, and it rapidly descends a series of pitches to a low aqueous passage that has been connected to Lost Johns' Cave. It is part of the Three Counties System, an cave system that spans the borders of Cumbria, Lancashire, and North Yorkshire. Description The entrance shaft descends some , and the way on is through the water descending from Rumbling Beck Cave above into a fault passage. Four further pitches descend into a chamber to a low canal passage. Upstream gets too low after some 60 metres, but downstream has been forced round some awkward bends and through some ducks into Rumbling Hole Inlet in Lost Johns' Cave. This section of cave is about long. An alternative route begins from a passage entered a few metres below the west end of the entrance shaft. These passages are, in the main, tighter and more complex than the main route, but the main passage descends an alternative s ...

Mississippian (geology)
The Mississippian ( , also known as Lower Carboniferous or Early Carboniferous) is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years. The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley. The Mississippian was a period of marine transgression in the Northern Hemisphere: the sea level was so high that only the Fennoscandian Shield and the Laurentian Shield were dry land. The cratons were surrounded by extensive delta systems and lagoons, and carbonate sedimentation on the surrounding continental platforms, covered by shallow seas. In North America, where the interval consists primarily of marine limestones, it is treate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
