WOW AND MORE WOW
This is the interior of Britain's biggest known cave chamber named Gaping Gill.
The main chamber is 476 feet long, 82 feet wide and 115 feet from floor to vaulted ceiling.
Cave enthusiasts were winched one by one down the gigantic pothole in Ingleborough, North Yorkshire - a descent that takes a full minute to reach the floor.
The cavern was formed by the action of a stream, Fell Beck, which flows from the flank of 2,373ft Ingleborough, the second highest mountain in the Yorkshire Dales, on to limestone rocks and roars down a dizzying 360ft drop in a natural fault line which makes it Britain's highest unbroken waterfall - twice the height of Niagara.
