Also known as John Stump, the Head Stone is another example of a Peak District stone that is said to turn around on a 'certain' morning each year on hearing the cocks-crow. (others include Baslow's Eagle Stone and the Cuckoo Stone in Matlock)
Visitors to the stone in late August with the sun highlighting its western face have also reported seeing a human face.
