While taking Images of Avebury Stones between 23.00 and 0.30 on May the 22nd this ghostly figure appeared on one of my images. Some have said that there is even an alien face in this image.
This could indeed be a result of trick of the light and various shading on the stone - however if that is the case then its very interesting how the combination of light and shade can produce such an image - so we are not discounting this entirely.
