It was seen, photographed twice, and then lost. What makes it unusual is not what it is, but how precarious its existence in the record has always been, dependent entirely on an accidental event and a single observer.

In the spring of 1952, a bog fire on Duntryleague Hill burned away roughly a foot of turf, exposing a circle of stones approximately six yards in diameter. Dr. Caoimhín Ó Danachair, a folklore and material culture scholar, visited the site in May of that year and recorded what he saw. He noted that the circle lay about thirty yards from an established megalithic tomb nearby, and that it sat on a direct alignment between that tomb and the tower of the old church in Ballylanders village, some four to five kilometres to the south-south-west. A kerb, in archaeological terms, is the ring of stones set around the base of a burial mound to retain its shape; Ó Danachair believed this arc might be just such a feature, the outer edge of a long-buried cairn. He returned in August 1953 to take two photographs, by which point heather and moss had already begun to reclaim the stones. He was clear that he did not believe the feature had been visible at any point before the fire. By 1984, when Ó Nualláin and Cody conducted a survey published in 1987, a plantation forest of closely grown trees covered the area, and a search failed to locate anything matching Ó Danachair's description.

The site carries a preservation order under the National Monuments Acts 1930 to 2014, which offers legal protection even to monuments whose physical presence is uncertain. In practical terms, the dense commercial forestry that now covers this part of Duntryleague Hill makes any visit difficult, and there is no guarantee that the stones are visible or even findable. The nearby megalithic tomb, recorded separately, is the more reliably accessible feature in this upland area. Anyone drawn to the hill should be prepared for rough terrain and the particular frustration of searching for something that may only ever surface again by accident, in the aftermath of fire or clearance, as it did once before.
