Wow, that's pretty special.
TSC, it looks like it was a side-slab on this link. ucl.ac.uk/prehistoric/past/past51.html#Balblair
Great stuff either way.
Ah, yes so it was. Amazing thing.
I almost went to look for the cairn at the end of my Beauly day out in October, but it's not on the map - I hadn't put two and two together and associated it with this until I got home and realised it was gone.
