I apologise for the very fuzzy nature of this and the accompanying photo (damn autofocus). The only reason i have included them is because they are geologically interesting. There is evidence for there having been, at one time, a lake in Battlefield Cavern, which has now dried up (perhaps due to minor earth movements). The resultant polygonal cracks in the residual mud have begun to infill with pale coloured calcium carbonate. This is the only place in Europe where this phenomenon has been discovered. As a result the cracks have been designated a S.S.S.I.
