No earthwork survives above ground; what exists is the ghostly magnetic trace of a fosse, the term used for a ditch encircling a feature of archaeological significance, detected only when a gradiometer was passed over the field. The instrument measures subtle variations in the soil's magnetic properties left behind by ancient digging, and in this case it revealed not one such feature but four ring-ditches and an enclosure clustered in the same area, near the point where a small stream meets the Corock River as it bends from an east-west course to run north-south.

The survey work, carried out in 2020 and reported by Nicholls, covered land that had once formed part of the demesne of Coolcliffe House, though this particular ring-ditch lay just outside that boundary. The feature itself is defined by a single encircling ditch with a gap of about two metres on the south-east side, which would have served as an entrance. Ring-ditches of this kind are generally understood to be the ploughed-down or silted-up remains of Bronze Age burial monuments, the circular ditches that once surrounded a central mound or cairn. Whether any burial remains beneath the surface here is unknown without further investigation, but the south-east-facing entrance aligns with a solar orientation common in prehistoric funerary practice, and the position overlooking a river confluence may be deliberate rather than incidental. Such liminal spots, where watercourses meet or change direction, recur with quiet frequency in the landscape choices of prehistoric communities.
