Hello Brian , no RA or anything else recorded in the area .There is a barrow (unexcavated) about a mile away to the east and that's it . The marked rocks stretch for about a mile and go over the watershed to the west . What is striking is that Dunnottar conglomerates are the basic geology and they are almost impossible to carve on being very tough , brittle and full of pebbles , but the area has a some intrusive sandstone and that's where the markings are . The loch is unsighted as is the barrow from all the sites . The rock is reminiscent of Galloway .
