There is considerable dispute over whether the two stones here (HY25492444 and 25542442) are the ones originally described, and if so as to to whether one or both moved since then !
In the Proceedings of the Society of Orkney Antiquaries John Fraser describes a 4’x3’x1’ standing stone at the edge of The Loons with a recumbent nearby. Fuller details are 3’6"x3’x10” and second stone 12’9’ away that is 3’x1’x8”.
