The Heavenly Pit is a sinkhole in China, located in the Chongqing area. It is a double sinkhole that measures 662 meters deep, 626 meters long and 537 meters wide; its upper "bowl" goes 320 meters deep and the lower one another 342 meters. Such a huge depression certainly did not appear overnight, and formed gradually over 128 thousand years. It is so large that it is often visited by extremists who want to get a burst of adrenaline by jumping down from a huge height with a parachute or on a rope.
