Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground.
Ursula Southeil, popularly known as Mother Shipton, is said to have been an English soothsayer and prophetess.
North Yorkshire is a ceremonial county in the North of England. It is mostly located in the Yorkshire and Humber region, but the area around the Tees Valley is in the North East. The largest county in England by land area, it measures 2,483 square miles (6,430 km2) and has a population of 1,158,816 (2021). The county town is Northallerton.
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as vrtače and shakeholes, and to openings where surface water enters into underground passages known as ponor, swallow hole or swallet. A cenote is a type of sinkhole that exposes groundwater underneath. Sink and stream sink are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock.
The Yorkshire Dales is an upland area of the Pennines in the historic county of Yorkshire, England, most of it in the Yorkshire Dales National Park created in 1954.
Harrogate is a spa town and the administrative centre of the Borough of Harrogate in North Yorkshire, England. Historically in the West Riding of Yorkshire, the town is a tourist destination and its visitor attractions include its spa waters and RHS Harlow Carr gardens. 13 miles (21 km) away from the town centre is the Yorkshire Dales National Park and the Nidderdale AONB. Harrogate grew out of two smaller settlements, High Harrogate and Low Harrogate, in the 17th century. For three consecutive years (2013–2015), polls voted the town as "the happiest place to live" in Britain.
Knaresborough is a market and spa town and civil parish in the Borough of Harrogate, in North Yorkshire, England, on the River Nidd. It is 3 miles (4.8 km) east of Harrogate.

Its council was based in the town of Harrogate, but it also included surrounding towns and villages. This included the cathedral city of Ripon and almost all of the Nidderdale Area of Outstanding Natural Beauty.
A petrifying well is a well or other body of water which gives objects a stone-like appearance. If an object is placed into such a well and left there for a period of months or years, the object acquires a stony exterior.
Nidderdale, historically also known as Netherdale, is one of the Yorkshire Dales in North Yorkshire, England. It is the upper valley of the River Nidd, which flows south underground and then along the dale, forming several reservoirs including the Gouthwaite Reservoir, before turning east and eventually joining the River Ouse.
The Borra Caves are located on the East Coast of India, in the Ananthagiri hills of the Araku Valley of the Alluri Sitharama Raju district in Andhra Pradesh. The caves, one of the largest in the country, at an elevation of about 705 m (2,313 ft), distinctly exhibit a variety of speleothems ranging in size and irregularly shaped stalactites and stalagmites. The caves are basically karstic limestone structures extending to a depth of 80 m (260 ft), and are considered the deepest caves in India.==History== The native name for the caves is Borra Guhalu. Where Borra means abdomen in Telugu language and guhalu means caves in Telugu language
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.
The River Nidd is a tributary of the River Ouse in the English county of North Yorkshire. In its first few miles it is dammed three times to create Angram Reservoir, Scar House Reservoir and Gouthwaite Reservoir, which attract a total of around 150,000 visitors a year. The Nidd can overflow the reservoirs, flooding the caves in the valley. In such cases the river overflows into the normally dry river bed past Lofthouse through to Gouthwaite Reservoir. The Yorkshire Dales Rivers Trust YDRT has a remit to conserve the ecological condition of the River Nidd from its headwaters to the Humber estuary.
Knaresborough Town Association Football Club is a football club based in Knaresborough, North Yorkshire, England. They are currently members of the Northern Counties East League Premier Division and play at Manse Lane.
Robert of Knaresborough was a British hermit who lived in a cave by the River Nidd, Knaresborough, North Yorkshire. His feast day is on the 24th of September.
Stump Cross Caverns is a limestone cave system between Wharfedale and Nidderdale in North Yorkshire, England.
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. It surrounds the high point of Gragareth 627 metres (2,057 ft) between Leck Beck and 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.
Warren's Cave is a dry karst cave in Alachua County, Florida. It is the longest dry cave in Florida, with more than 4 miles (6.4 km) of mapped passages. The cave is located on the margin of the Cody Scarp near the San Felasco Hammock Preserve State Park, northwest of the city of Gainesville. The property on which the entrance to Warren's Cave is located, the Warren Cave Nature Preserve, is owned by the National Speleological Society. Warren's cave was probably formed by a high water table when sea levels in the Quaternary Period were elevated close to 100 feet (30 m) above current sea level, corresponding to the Wicomico terrace.
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.
