Skirwith Cave is a major resurgence solutional cave on Ingleborough in Chapel-le-Dale, North Yorkshire, England; it was a show cave between 1964 and 1974. It is no longer open to the public but is still visited by cavers. It lies within the designated Ingleborough Site of Special Scientific Interest. [3]

Description

The current entrance is through an opening in a small shakehole. This drops into a well-decorated rift passage, which was part of the former show cave. A levelled floor reaches a boulder choke which once had a flight of steps leading over it; this is now covered by a boulder collapse. The show cave terminated at a five-metre (16 ft) waterfall. Above this, a long, mainly low, wet passage reaches a sump after several hundred metres. This is the first of three short sumps separated by short sections of passage. The fourth sump has been dived for 24 metres (79 ft) to an underwater boulder choke. The cave has no inlet passages in its 1,000-metre (3,300 ft) length. [1]

Geology and hydrology

Skirwith Cave is a solutional cave formed in the lowest beds of the Visean Great Scar limestone from the Mississippian Series of the Carboniferous period, which here lies unconformably on impervious Ordovician rocks. The cave runs up dip NNE towards the valley of Crina Bottom, and drains the area around Boggarts Roaring Holes on the other side of the valley, although in times of flood it also takes water from overflow sinks in Crina Bottom itself. [4] A fragment of the continuing passage has been entered from Lower Hardgill Pot, some 400 metres (1,300 ft) away in Crina Bottom. [5] The water resurges on the basal unconformity.

History

It is thought that the cave was first entered by locals in 1934, and at least some of the upstream passages were further explored by members of the Yorkshire Ramblers' Club in 1935. [6] By 1947, the cave had been fully explored to the first sump. [7] The sumps were explored in 1965 and 1966 by members of the Happy Wanderers Cave and Pothole Club. [8]

The cave was opened as a show cave in 1964; it was always a smaller commercial operation than the nearby showcaves Ingleborough and White Scar, and more difficult of access for visitors. Blasting from the local quarry destabilized the roof and boulder piles, and the cave was closed in 1974. Little evidence remains above ground of its use as a show cave. [9]

Ingleborough is the second-highest mountain in the Yorkshire Dales, England. It is one of the Yorkshire Three Peaks, 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.

Gaping Gill is a natural cave in North Yorkshire, England. It is one of the unmistakable landmarks on the southern slopes of Ingleborough – a 98-metre (322 ft) deep pothole with the stream Fell Beck flowing into it. After falling through one of the largest known underground chambers in Britain, the water disappears into the bouldery floor and eventually resurges adjacent to Ingleborough Cave.

Rowten Pot is one of several entrances into the 27-kilometre (17 mi) long cave system that drains Kingsdale in North Yorkshire, England. Its entrance is a shaft some 27 metres (89 ft) long, 10 metres (33 ft) wide, and at the southern end 72 metres (236 ft) deep.

The Marble Arch Caves are a series of natural limestone caves located near the village of Florencecourt in County Fermanagh, Northern Ireland. The caves are named after the nearby Marble Arch, a natural limestone arch at the upstream end of Cladagh Glen under which the Cladagh River flows. The caves are formed from three rivers draining off the northern slopes of Cuilcagh mountain, which combine underground to form the Cladagh. On the surface, the river emerges from the largest karst resurgence in Ireland, and one of the largest in the United Kingdom. At 11.5 kilometres (7.1 mi) the Marble Arch Caves form the longest known cave system in Northern Ireland, and the karst is considered to be among the finest in the British Isles.

Great Douk Cave is a shallow cave system lying beneath the limestone bench of Ingleborough in Chapel-le-Dale, North Yorkshire, England. It is popular with beginners and escorted groups, as it offers straightforward caving, and it is possible to follow the cave from where a stream emerges at a small waterfall to a second entrance close to where it sinks 600 yards (549 m) further up the hill. It lies within the Ingleborough Site of Special Scientific Interest.

Langcliffe Pot is a cave system on the slopes of Great Whernside in Upper Wharfedale, about 3 kilometres (1.9 mi) SSE of Kettlewell in North Yorkshire. It is part of the Black Keld Site of Special Scientific Interest where the "underground drainage system which feeds the stream resurgence at Black Keld is one of the largest and deepest in Britain, although only a small proportion of its cave passages are accessible at present." Mossdale Caverns is also part of the Black Keld SSSI. Although a considerable length of passage has been explored in Langcliffe Pot, the current end is over 170 metres (560 ft) above the resurgence, and over 4 kilometres (2.5 mi) in distance. A trip to the far end has been described as "one of the most serious undertakings in British caving".

Short Drop Cave and Gavel Pot are different entrances into the same cave system on Leck Fell, in Lancashire, England. The main top entrance, Short Drop Cave, is a small hole in a fenced off shakehole near the main stream sink; Gavel Pot, a window into the system, is a large fenced shakehole some 40-metre (130 ft) deep requiring tackle to descend. There are two other smaller entrances into Short Drop Cave. At its base the system links via a sump with Lost Johns' Cave, and is part of the Three Counties System, an 87 kilometres (54 mi) cave system which spans the borders of Cumbria, Lancashire, and North Yorkshire.

Rat Hole is one of the entrances to the Gaping Gill cave system, located in the north bank of Fell Beck 30 metres (33 yd) upstream of Gaping Gill Main Shaft. A small, awkward, tube-like passage descends into a stream passage, and hence to a 100-metre (330 ft) shaft into Gaping Gill Main Chamber. The sharp and loose nature of the rock, and the quantity of water prevented full exploration for over 80 years, but the current route is described in one guide book as "a technical and exhilarating adventure".

The Three Counties System is a set of inter-connected limestone solutional cave systems spanning the borders of Cumbria, Lancashire and North Yorkshire in the north of England. The possibility of connecting a number of discrete cave systems in the area to create a single super-system that spans the county borders was first proposed by Dave Brook in 1968, and it was achieved in 2011. The system is currently over 86 kilometres (53 mi) long, making it the longest in the UK and the thirtieth longest in the world, and there continues to be scope for considerably extending the 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.
