There is no earthwork to notice, no depression underfoot, nothing to suggest that the field holds anything beyond grass. The site exists, in a practical sense, only from the air.

Ring-ditches are the crop-mark ghosts of earlier monuments, most commonly the filled-in circular trenches that once surrounded Bronze Age burial mounds. When the mounds themselves were levelled by centuries of farming, the ditches silted up and the difference in soil composition above them causes crops or grass to grow at subtly different rates, a difference invisible at ground level but legible from above. At Clashdrumsmith, the cluster was identified through aerial photography, the three ditches grouped together in a triangular arrangement on a low rise at the base of a south-facing slope. The grass in the field is long and has fallen over, which makes even the faintest surface variation harder to read, and no visible trace has been recorded at ground level.
