Highest unbroken waterfall

A Natural Cave (Gaping Ghyll)

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 pathole with the stream fell back 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. It was discovered in 1999. Gaping Gill still retains the records for the highest unbroken waterfall in England and the largest underground chamber naturally open to the surface.
