The area around the Southern shore of Loch Naver is scattered with ancient remains consisting of hut circles, standing stones and cup marked stones. However the hut 'circles' turned out to be rectangular mostly, so it was difficult to know whether they were truly prehistoric or simply the remains of crofts left over from the Highland Clearances some 250 years ago or less. Equally the standing stones were the other side of a river descending from Ben Klibreck which forms the background to the area. The river, sadly, was uncrossable on this occasion so I didn't get to see them. I did, however, come across what appeared to be cup marks on a rock next to the river while trying to search out the standing stones. Whether they really are man-made cup marks or just natural erosion is hard to say.
