Goatchurch Cavern is a cave on the edge of Burrington Combe in the limestone of the Mendip Hills, in Somerset, England.
Due to early attempts to turn it into a show cave, [2] there are remains of iron handrails inside the cave and a large amount of decoration throughout the cave. Many of the surfaces within are highly polished and slippery, as a result of numbers visiting over many decades, which have also damaged the decoration.
The cave is especially popular for training people who are new to caving. This is due to its easy access and wide range of experiences that do not necessitate the use of special equipment such as ropes or ladders.
The two entrances to the cave enable cavers to do a through trip.[ clarification needed ]
The earliest written record of this cave was in 1736 when John Strachey of Sutton Court at nearby Stowey made reference to "guy Hole" or "Goechurch". In 1829 John Rutter wrote about the large cave and in 1864 William Boyd Dawkins referred to it as "The Goatchurch" although he also used the name "Goat's Hole" in 1874. It is possible that the local dialect corrupted "Guy" into "Goat" to provide the current name. [3]
It is thought that Goatchurch Cavern was explored by lead miners in the 19th century. [4] Around 1900 the owner unsuccessfully tried to turn it into a show cave. [2] In 1924 UBSS dug open the second entrance. [2]
Notes of exploration in the 1920s record finds from the Pleistocene period including bones of mammoth, bear, hyaena and cave lion. [2] [5] [6] During November 2003 inscribed marks were noticed in Goatchurch Cavern while cleaning away graffiti. Three finely cut marks were uncovered, resembling the letter W with a patina darker than in nearby graffiti dated 1704. These have been identified as ritual protection marks, possibly dating from the period 1550 to 1750. The term 'ritual protection mark' was preferred to the description "witch marks". [7]
The cave is historically understood to be approximately 750 metres (2,500 ft) long, although 1500 m (4900 ft) of surveyed passage has been measured (UBSS, unpublished survey, pending: 2007) and reaches a surveyed depth of 61.5 m (202 ft). It has two entrances and a complex network of predominately dry passages terminating, for most visitors, in a thin phreatic tube known as 'The Drainpipe' or 'The Bunny Run'. This is a long tight wriggle through 30 ft (9 m) of passageway that is only practically navigable whilst travelling forwards, something that is of relevance due to the Drainpipe terminating in a small blind-ending boulder chamber; meeting another caver halfway is not a pleasant experience. Another notable feature of the cave is 'The Coffin Lid'. This is where a rock, often likened to a coffin by cavers, partially blocks the way down.
A survey was conducted within Goatchurch Cavern to investigate the effect of seasonal variations on the recorded radon concentration, from which an average summer to winter ratio of 4.79 was determined. Radiation doses to users of the caves were estimated and for occupational cavers doses of in excess of 16 mSv were found to be likely. [8]
Wookey Hole Caves are a series of limestone caverns, a show cave and tourist attraction in the village of Wookey Hole on the southern edge of the Mendip Hills near Wells in Somerset, England. The River Axe flows through the cave. It is a Site of Special Scientific Interest (SSSI) for both biological and geological reasons. Wookey Hole cave is a "solutional cave", one that is formed by a process of weathering in which the natural acid in groundwater dissolves the rocks. Some water originates as rain that flows into streams on impervious rocks on the plateau before sinking at the limestone boundary into cave systems such as Swildon's Hole, Eastwater Cavern and St Cuthbert's Swallet; the rest is rain that percolates directly through the limestone. The temperature in the caves is a constant 11 °C (52 °F).
Cheddar Gorge is a limestone gorge in the Mendip Hills, near the village of Cheddar, Somerset, England. The gorge is the site of the Cheddar show caves, where Britain's oldest complete human skeleton, Cheddar Man, estimated to be 9,000 years old, was found in 1903. Older remains from the Upper Late Palaeolithic era have been found. The caves, produced by the activity of an underground river, contain stalactites and stalagmites. The gorge is part of a Site of Special Scientific Interest called Cheddar Complex.
The Mendip Hills is a range of limestone hills to the south of Bristol and Bath in Somerset, England. Running from Weston-super-Mare and the Bristol Channel in the west to the Frome valley in the east, the hills overlook the Somerset Levels to the south and the Chew Valley and other tributaries of the Avon to the north. The hills give their name to the local government district of Mendip, which administers most of the area. The higher, western part of the hills, covering 198 km2 (76 sq mi) has been designated an Area of Outstanding Natural Beauty (AONB), which gives it a level of protection comparable to a national park.
The River Axe is a river in South West England. The river is formed by water entering swallets in the limestone and rises from the ground at Wookey Hole Caves in the Mendip Hills in Somerset, and runs through a V-shaped valley. The geology of the area is limestone and the water reaches Wookey Hole in a series of underground channels that have eroded through the soluble limestone. The river mouth is in Weston Bay on the Bristol Channel.
Burrington Combe is a Carboniferous Limestone gorge near the village of Burrington, on the north side of the Mendip Hills Area of Outstanding Natural Beauty, in North Somerset, England.
Pen Park Hole is a large cavern situated underground, at the edge of Filton Golf Course. The cavern was discovered accidentally in the 17th Century and the first descent was made by Captain Sturmy in 1669. The entrance is adjacent to the Southmead and Brentry housing estates of north Bristol. Access is tightly controlled by Bristol City Council. It was scheduled as a Site of Special Scientific Interest in August 2016 on account of its geological origins, and its cave invertebrate community including the cave shrimp Niphargus kochianus, which is normally known as a spring seepage or chalk aquifer species.
Banwell Caves are a 1.7-hectare geological and biological Site of Special Scientific Interest near the village of Banwell, North Somerset, England notified in 1963.
Crook Peak to Shute Shelve Hill is a 332.2 hectare (820.9 acre) geological and biological Site of Special Scientific Interest near the western end of the Mendip Hills, Somerset. The line of hills runs for approximately 5 kilometres (3.1 mi) from west to east and includes: Crook Peak, Compton Hill, Wavering Down, Cross Plain and Shute Shelve Hill. Most of the site is owned by the National Trust, which bought 725 acres (293 ha) in 1985, and much of it has been designated as common land. It was notified as an SSSI by Natural England in 1952.
Priddy Caves is an Area: 67.6 hectare geological Site of Special Scientific Interest at Priddy in the Mendip Hills, Somerset, notified in 1965.
The Cheddar Complex is a 441.3 hectare biological Site of Special Scientific Interest near Cheddar around the Cheddar Gorge and north east to Charterhouse in the Mendip Hills, Somerset, England, notified in 1952.
Gough's Cave is located in Cheddar Gorge on the Mendip Hills, in Cheddar, Somerset, England. The cave is 115 m (377 ft) deep and is 3.405 km (2.12 mi) long, and contains a variety of large chambers and rock formations. It contains the Cheddar Yeo, the largest underground river system in Britain.
The caves of the Mendip Hills are formed by the particular geology of the Mendip Hills: large areas of limestone worn away by water makes it a national centre for caving. The hills conceal the largest underground river system in Britain.
Eastwater Cavern is a cave near Priddy in the limestone of the Mendip Hills, in Somerset, England. It is also known as Eastwater Swallet. It was first excavated in April 1902 by a team led by Herbert E. Balch composed of paid labourers and volunteers from the Wells Natural History Society. Progress was initially slow, but by February 1903 Balch and Willcox had discovered substantial passage, following the streamway down to the bottom of the cave. Dolphin Pot was dug in 1940 by the Wessex Cave Club, with Primrose Pot following in 1950. West End series was the most recent significant discovery, in 1983.
GB Cave is a cave between Charterhouse and Shipham in the limestone of the Mendip Hills, in Somerset, England.
Sidcot Swallet is a cave near Burrington Combe, in the Carboniferous Limestone of the Mendip Hills, in Somerset, England.
Charterhouse Cave, on the Mendip Hills in Somerset, is the deepest cave in southern England.
The Cheddar Yeo is a small river in Somerset, England. Beneath the limestone of the Mendip Hills it forms the largest underground river system in Britain. After emerging into Cheddar Gorge it flows through the village of Cheddar, where it has been used in the past to power mills. From the Middle Ages until the 19th century the river had ports for seagoing vessels but is no longer navigable. Some of the water, which is of good quality, is diverted into Cheddar Reservoir to provide drinking water for Bristol.
Read's Cavern is a cave at Burrington Combe, Somerset, England, in which traces of Iron Age occupation have been found. It lies under Dolbury Hill. Its large main chamber has a boulder ruckle floor and is parallel to a cliff face. The cave was excavated by the University of Bristol Spelæological Society (UBSS) in the 1920s, when relics of Iron Age occupation were found.
Reservoir Hole is a cave in Cheddar Gorge in Somerset, southwest England. It contains what is believed to be the largest chamber yet found under the Mendip Hills.
