Leck Fell is a Site of Special Scientific Interest in Lancashire, England. An area of typically heavily grazed open moorland of rough grass and remnant patches of heather with little or no tree cover, it is characterised by the virtual absence of surface drainage and an extensive subterranean drainage network resulting in cave systems and numerous sinkholes. [2] It surrounds the high point of Gragareth 627 metres (2,057 ft) between Leck Beck and Kingsdale. [1]
Since 1 August 2016, Leck Fell has been part of the Yorkshire Dales National Park. [3]
This site consists of a network of cave systems and their catchment areas, with Ease Gill Caverns being the longest cave system in Britain. There are fourteen major sinkholes through which surface water enters the system, with water returning to the surface at Leck Beck Head. The botanical interest of the site is due to the underlying Carboniferous Limestone, which appears above ground as features such as crags, limestone pavements, gorges and potholes. [1] The pasturing of animals, along with changes in the climate in the later Bronze Age, contributed to deforestation of the open fell sides and the development of hill peat deposits. [2] The present landscape is dominated by long straight enclosure walls of late 18th or 19th century date. [2]
At Easegill, the limestone cliffs support rigid buckler fern, limestone polypody and mossy saxifrage. Downstream from here, in a steep wooded gorge, there are eleven species of fern and such plants as wood forget-me-not, hairy rock-cress, wall lettuce, sanicle and whitlow grass. In contrast, the more acid rock at Aygill supports wood rush, hard fern and beech fern. The steep slopes around some potholes have similar "woodland"-type flora. In some places there are limestone pavements, in whose cracks and fissures grow ferns and the unusual subshrub baneberry, out of reach of grazing sheep. [1]
The 87-kilometre (54 mi) Three Counties System, which extends from Kingsdale to Barbondale, includes a number of important cave systems lying beneath Leck Fell. These include:
A formal permitting system operates for access to most of the caves. [4]
The Pennines, also known as the Pennine Chain or Pennine Hills, are a range of uplands mainly located in Northern England. Commonly described as the "backbone of England" because of its length and position, the range runs from the north Midlands to North East England, near the Anglo-Scottish border. The Peak District is the southern end of the range, rising northwards from its foothills near the Trent Valley in northern Staffordshire, and further north into eastern Cheshire and southern Derbyshire. Beyond this are the South Pennines, Yorkshire Dales, and North Pennines, ending at the Tyne Gap. Beyond the gap are the Border Moors and Cheviot Hills, which are included in some definitions of the range.
The Yorkshire Dales are an upland area of the Pennines in England. Most of the area is in the county of North Yorkshire, but it extends into Cumbria and a small part of Lancashire. It was historically entirely within Yorkshire. The majority of the Dales are part of the Yorkshire Dales National Park, created in 1954. The exception is the area around Nidderdale, which forms the separate Nidderdale Area of Outstanding Natural Beauty.
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.
The Ease Gill Cave System is the longest, and most complex cave system in Britain as of 2011, with around 41 miles (66 km) of passages, including connections only passable by cave diving. It spans the valley between Leck Fell and Casterton Fell. The water resurges into Leck Beck.
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.
Carboniferous Limestone is a collective term for the succession of limestones occurring widely throughout Great Britain and Ireland that were deposited during the Dinantian Epoch of the Carboniferous Period. These rocks formed between 363 and 325 million years ago. Within England and Wales, the entire limestone succession, which includes subordinate mudstones and some thin sandstones, is known as the Carboniferous Limestone Supergroup.
Leck Beck is a watercourse in Lancashire with its source on Crag Hill in Cumbria between Leck Fell and Casterton Fell.
Gragareth is a mountain straddling the border between Lancashire and North Yorkshire in England. At 627 metres (2,057 ft), its summit is the second highest point in the post-1974 county of Lancashire. The highest point in modern Lancashire is Green Hill, approximately 3.2 km (2.0 mi) to the north and the Old Man of Coniston in the Furness Fells of the Lake District at 803 metres (2,635 ft) is the county top of the traditional county of Lancashire. The summit of Gragareth lies about 200 m west of the county boundary, but inside the 2016 border of Yorkshire Dales National Park. The western slopes are known as Leck Fell and the southern slopes form Ireby Fell.
Rumbling Hole is a cave on Leck Fell, in Lancashire, England. Its entrance is a 50-metre (160 ft) 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 87-kilometre (54 mi) cave system that spans the borders of Cumbria, Lancashire, and North Yorkshire.
Aquamole Pot is a limestone cave in West Kingsdale, North Yorkshire, England. It was originally discovered by cave divers who negotiated 168 metres (551 ft) of sump passage from Rowten Pot in 1974, to enter a high aven above the river passage. All subsequent major explorations were undertaken from below before an entrance was opened up from the surface. It is part of a 27-kilometre (17 mi) long cave system that drains both flanks of Kingsdale.
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.
Yordas Cave is a solutional cave in Kingsdale, North Yorkshire, England. It has been renowned since the eighteenth century as a natural curiosity, and was a show cave during the nineteenth century. It is now a popular destination for cavers, walkers, and outdoor activity groups.
Death's Head Hole is a cave on Leck Fell, in Lancashire, England. Its entrance is a 64-metre (210 ft) deep shaft. It leads into Lost Johns' Cave and is part of the Three Counties System, an 87-kilometre (54 mi) cave system which spans the borders of Cumbria, Lancashire, and North Yorkshire.
Lost Pot is a cave on Leck Fell, in Lancashire, England. It leads into the top end of 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.
Boxhead Pot is a cave on Leck Fell, in Lancashire, England. It leads into the top end of 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.
Long Drop Cave is a cave on Leck Fell, in Lancashire, England. It leads into Death's Head Hole, and is part of the Three Counties System, an 87-kilometre (54 mi) cave system which spans the borders of Cumbria, Lancashire, and North Yorkshire.
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.
Swinsto Cave is a limestone cave in West Kingsdale, North Yorkshire, England. It leads into Kingsdale Master Cave and it is popular with cavers as it is possible to descend by abseiling down the pitches, retrieving the rope each time, and exiting through Valley Entrance of Kingsdale Master Cave at the base of the hill. It is part of a 27-kilometre (17 mi) long cave system that drains both flanks of Kingsdale.
Jingling Pot is a limestone cave in West Kingsdale, North Yorkshire, England. Located adjacent to Jingling Beck, it is a lenticular-shaped 45-metre (148 ft) deep shaft that descends straight from the surface. At the bottom the rift extends to the north and descends steeply into a further chamber, at the end of which the initials of the original explorers may be seen scratched into the rock. A narrow shaft in this second chamber drops into a complex of small crawls and rifts, which approach close to a passage in the One-armed Bandit Series of Aquamole Pot. A second set of shafts descend parallel to the surface shaft. These can be entered through a rock window a little way below the entrance.
Chapel-le-Dale is west-facing valley in the Yorkshire Dales, England. The U-shaped valley of Chapel-le-Dale is one of the few which drain westwards towards the Irish Sea, however, the river that flows through the valley has several names with the Environment Agency and the Ordnance Survey listing it as the River Doe. However, some older texts insist the name of the watercourse through the dale is the River Greta, which runs from a point below the hamlet of Chapel-le-Dale, and onwards past Ingleton. The dale is sparsely populated with only one settlement, the hamlet of Chapel-le-Dale, which has a small chapel.
