Hi Eds,
Cheers for that - I hadn't realised that Rhiannon's "cairn" related to the pair of chambered cairns in the woods - I had assumed it was also the summit one with the folklore associated, hence my concern about grid refs (sorry Rhiannon).
Thanks for sorting. I think the use of Strath, etc for some sites but not for others may have led to much of the confusion.
