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 ...

Limestone
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 limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |

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 ...

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

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] |
Lancashire
Lancashire ( , ; abbreviated Lancs) is the name of a historic county, ceremonial county, and non-metropolitan county in North West England. The boundaries of these three areas differ significantly. The non-metropolitan county of Lancashire was created by the Local Government Act 1972. It is administered by Lancashire County Council, based in Preston, and twelve district councils. Although Lancaster is still considered the county town, Preston is the administrative centre of the non-metropolitan county. The ceremonial county has the same boundaries except that it also includes Blackpool and Blackburn with Darwen, which are unitary authorities. The historic county of Lancashire is larger and includes the cities of Manchester and Liverpool as well as the Furness and Cartmel peninsulas, but excludes Bowland area of the West Riding of Yorkshire transferred to the non-metropolitan county in 1974 History Before the county During Roman times the area was part of the Bri ...

Solutional Cave
A solutional cave, solution cave, or karst cave is a cave usually formed in the soluble rock limestone. It is the most frequently occurring type of cave. It can also form in other rocks, including chalk, dolomite, marble, salt beds, and gypsum. Process Bedrock is dissolved by natural acid in groundwater that seeps through bedding-planes, faults, joints and so on. Over geological epochs these openings expand as the walls are dissolved to become caves or cave systems. The portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded. Limestone caves The largest and most abundant solutional caves are located in limestone. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation. These include flowstones, stalactites, stalagmites, helictites, soda straws, calcite rafts and columns. These secondary mineral deposits in caves are called ''speleothems''.
