Experts examining aerial photos of the formation have concluded that there is evidence of human activity from marks made by the wooden boards employed by crop circle makers.
Dr Horace R Drew, writing on the Crop Circle Connector website, claims he has found a foolproof way of working out which formations are of human origin and which may be the work of ‘non-human forces’.
He said: “It is often hard to tell whether a new crop picture might be paranormal or human-made. Recently I found a new method to detect human ‘board marks’ from aerial images, by using a standard Photoshop program to reduce midtone contrast.
“This method allowed for easy detection of regular board marks in several human-made crop pictures from the past, for example the ‘dolphins’ at Golden Ball Hill in July of 2004.
“A crop picture at Manton Drove on June 2, 2012 also shows a series of regularly striped features, which could perhaps be human board marks.”
He added: “Nor was the imagery of this crop picture particularly clever: just a ‘Polar Clock 3’ screensaver that can be downloaded free off the web. The crop picture shows a polar-clock date of Saturday, August 4, sometime in the evening from 6–7pm.
