“A line of large stones on Dunsley Moor is said to have run between the Swart Howe and another barrow. Two of the stones are further stated to have been carved in a style similar to that of a stone, now lost, found within the Howe which contained a burial of the urn period. Knox describes four stones about 3 feet high at this site, which formed an oblong.”
