Stoke Lane Slocker (grid reference ST66874745 ) is a cave near Stoke St Michael, in the Carboniferous Limestone of the Mendip Hills, in the English county of Somerset.

Contents

It is 2.18 km in length and reaches a depth of 30m. [1]

It was previously known as Stoke Lane Swallet, but now the local name is preferred. The origin of the word "Slocker" is obscure, possibly from "slock" meaning to entice or lure away [2] although the Gaelic word for swallow hole is "sluighaire".

History

It is believed that the first person to explore the cave in modern times was a Mr Marshall from Stratton-on-the-Fosse around 1905, but major exploration and measurement of this cave really started in 1947 when Sump 1 was reached. That sump was passed the same year and the decorated chambers of Stoke Two discovered. Sumps 2 to 7 were passed over the course of the 1960s. The Bailey-Ward series of chambers was discovered in 1971. [1] [3]

Cases of Weils Disease have been reported in those who have been into the cave. [1] [4]

Description

The submerged entrance to the cave lies near the disused Stoke Lane Quarry, and from it an underground stream emerges into daylight to feed a water-source known as St Dunstan's Well. The cave has been designated as a Site of Special Scientific Interest. [5]

Stoke One (the length of passage between the entrance and Sump 1), is mainly made up of low passageways. However the Bailey-Ward Series of chambers includes Bernard's Rift, which is 20 metres (66 ft) high and contains crystal pools containing calcite-encrusted goniatite snail shells, and cave pearls. [1]

The area between Sumps 1 and 2, Stoke 2, contains a number of highly decorated chambers including the Upper Grotto, Traverse Grotto and the Throne Room which contains a 3 metres (10 ft) high stalactite boss named The King and a second stalactite, 2 metres (7 ft) high, named The Queen after Queen Victoria. The once-spectacular formations in the Princess Grotto have suffered damage since the cave was discovered. When the Bone Chamber, which is not decorated, was found it contained a number of human and animal bones, along with ash and charcoal. [1]

Beyond the second sump is a long stretch of passage containing a further six sumps.

Wookey Hole Caves Series of limestone caverns in Somerset county, England

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).

River Axe (Bristol Channel) River in Somerset, England

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.

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.
