RCAHMS NMRS record no. HY40NE 20 at HY48330698 is a much-quarried earth-and-stone feature about fourteen metres across and a metre high that is covered by peat. This prominent site is the one shown on the O.S. map as a cairn.
From another source I find it is now reduced to a height of 0.7m, and that there is another cairn close by. Source not noted.
