This rock reminded me of the stones of Avebury and other prehistoric sites I have visited in the past – although this one is most certainly a natural outcrop, rather than something deliberately placed. I did not get a chance to make a close examination of this rock, but it is on the edge of an area where ‘Cup and Ring’ marked stones are found.
For once, conditions gave me a nice raking light which helped to show the striations on the side of the rock.
