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 pothole 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.〔(【引用サイトリンク】title=Gaping Gill - A list of entrances )〕〔(【引用サイトリンク】title=Gaping Gill )〕 The shaft was the deepest known in Britain, until Titan in Derbyshire was discovered in 1999. Gaping Gill still retains the records for the tallest unbroken waterfall in England and the largest underground chamber naturally open to the surface. ==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,〔(【引用サイトリンク】title=Gaping Gill )〕 and the Craven Pothole Club around August Bank Holiday,〔(【引用サイトリンク】title=Gaping Gill )〕 each set up a winch above the shaft to provide a ride to the bottom and back out again for any member of the public who pays a fee. 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gaping Gill」の詳細全文を読む スポンサード リンク
