Gaping Gill (also known as Gaping Ghyll) is a natural cave in North Yorkshire, England. It is one of the unmistakable landmarks on the southern slopes of Ingleborough – a deep Pit cave 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.
The shaft was the deepest known in Britain, until Titan in Derbyshire was discovered in 1999.
Features
Due to the number of entrances which connect into the cave, many different routes through and around the system are possible. Other entrances include
Jib Tunnel, Disappointment Pot, Stream Passage Pot,
Bar Pot, Hensler's Pot, Corky's Pot, Rat Hole, and Flood Entrance Pot.
The Bradford Pothole Club around Whitsun May Bank Holiday,
A detailed 3D model of the chamber has been created using an industrial laser rangefinder which showed that its volume is comparable to the size of York Minster.
History of exploration
Descents
The first recorded attempted descent was by
John Birkbeck in 1842 who reached a ledge approximately down the shaft which bears his name.
The first complete descent was achieved by Édouard-Alfred Martel in 1895.
Hensler's Crawl and Master Cave
On 16 May 1937
Eric Hensler (1907–1991) explored a low passage leading off Booth-Parsons crawl, finding it to be unexplored. This was later named Hensler's Crawl and was also found to lead into Hensler's Master Cave.
Since 1937
In 1983 members of the Cave Diving Group made the underwater connection into Ingleborough Cave.
An extreme rock-climb (Climbing grade E3, 5c) is possible up the main shaft which requires very dry conditions. It was first pioneered in 1972 with ten points of aid. The first free ascent was made in 1988.
