Smack dab in the middle of the U.K. is a quarry with one of the most terrifying images that mother nature has ever come up with. This old slate quarry has long been used as a diving spot, with a network of dangerous faces and has been known for it’s fair share of deaths over the years. But that’s not the scariest part.

Back in 2011, a photographer noticed that when the water is smooth, a perfect image of a skull is created. Half of the skull is created by the side of a cliff and a cave, and the smooth water does the rest. Add in some mist and creepy winds coming out of the underground and you got yourself an entrance to the land of the dead.

Spooky stuff.
