The image, taken on 14 July, revealed a cropmark in the soil: a circular ditch roughly ten metres in diameter, its presence betrayed only by the differential growth of whatever crop was in the ground. A cropmark forms when buried features, such as ditches, affect how plants above them grow, typically producing lusher or paler strips that become legible only from the air and only under the right conditions. What the photograph showed was a ring-ditch, a roughly circular or oval earthwork cut into the ground, generally associated with prehistoric funerary or ritual activity, often the remains of a burial mound whose raised earthwork has long since been ploughed away.

What makes this particular site quietly arresting is that it is not alone. The same aerial photograph places this ring-ditch as the middle one in a group of three, the others spaced roughly sixty to seventy metres apart and arranged along a north to south alignment. A fourth ring-ditch lies approximately a hundred metres to the north-north-west. The spacing and alignment suggest these were not random or incidental features but part of a deliberate, organised landscape, perhaps a funerary corridor or a cluster of related monuments. Whether they were all in use at the same time, or accumulated over generations, cannot be determined from the cropmark evidence alone. They survive now only as shadows in a tilled field, their physical form erased by centuries of agriculture, legible only through the patience of aerial survey.
