Quick aside, sorry Hob, despite being at castlerigg for sunrise & sunset, I couldn't see the spiral...

On a better note I did take a photo of a lozenge shaped carving on a stone on the East side of the circle that was really clear at sunset. Which was nice.

Thanks a lot, Hob: I'll try to set up the link, but I'm afraid there is a technophobic side to me. If I hit a problem (again) I might come back for advice! Treeman
