No entrance is visible today, no kerb stones frame its edge, and no internal structure has been formally identified, yet the memory of something hollow at its centre persisted in local knowledge well into the twentieth century.

The cairn was noted by Price and Walshe in 1933, who recorded the oral tradition about the cave and tunnel. Decades later, the archaeologist Michael Herity proposed in 1974 that it might be a passage tomb, a type of prehistoric monument in which a stone-lined corridor leads to a burial chamber within a covering mound. The absence of any visible kerb or structural remains makes this classification uncertain, and the site remains unexcavated. That ambiguity is part of what makes it interesting: a mound large enough to be significant, old enough to carry legend, and still not fully understood.

What is known with more recent certainty is that the cairn has been damaged. An inspection in October 2022 found two oval holes dug into the summit, each roughly a metre long and up to eighty centimetres deep, with displaced stones thrown to the sides. More seriously, a much larger excavation had been cut into the northern edge of the cairn, approximately three metres long and up to two metres deep, with removed stones scattered around it. The damage appears to have been deliberate, and the National Monuments Service has been investigating. Whether those responsible were motivated by the old story of a tunnel, or by something else entirely, is not recorded.
