You heard anything about the cairn on top of Geallaig Hill? It's not on canmore.

If you ignore the wind shelter built on top of it, the shape looks to have more in common with the old cairns just to the east like on Morven, Pressendye etc compared to the modern cairns on the hills to the west.
Couple of photos - probably just wishful thinking.

To the north west there are hut circles.
I'll post pics here and put up a site page so we can discuss further. I'll send pics to Historic Scotland, Bruce at Aberdeenshire Archaeology and Ian Suddaby at CAD archaeology. Any feedback will, of course, be shared here.
