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 98-metre (322 ft) deep pothole with the stream Fell Beck flowing into it.[3] 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.[1][4]
The shaft was the deepest known in Britain, until Titan in Derbyshire was discovered in 1999.[5] Gaping Gill still retains the records for the highest unbroken waterfall in England and the largest underground chamber naturally open to the surface.
