here. It, and the comment from Matt, has made us more aware of the differences between, and the possible purposes of the many cairns we come across on our walks across this beautiful peninsula. The one in this photograph is one of a rare kind, in which all the stones are evidently old - in this case, because all are covered in moss. As can be seen, it's about a kilometre from Ardnamurchan Point lighthouse and, like many of the other old cairns, it occupies no more than a low hill.
Possibly these cairns are markers, delineating the boundaries between fields or other land possessions, and perhaps some have a greater significance, such as grave markers.
