AVEBURY TRUSLOE 2006
Analysis based on angled photo adjusted in Photoshop.
Main circle diameters are approximately in ratio 1: 0.66: 0.50. 0.33
Formation of the circles would require a series of centre points as marked. This could be achieved by careful walking between the drill lines.
The formation lines up precisely with the tram lines in the field. For these reasons, a man-made origin seems likely.
