This cup-marked slab of schist is situated underneath a hidden rock shelter in Gleann Da-Eig, a side valley of Glen Lyon. It was found by George Currie in 2006 and probably not visited since until I uncovered it again in July 2022. The overhanging rock is obviously much used as a shelter to this day, but for the local sheep since the slab was buried beneath a good covering of compacted sheep....err...manure.
