The friend I was with actually took me to the Comet stone first Resonox as she thought it was the place to view from, myself just wanting to take the normal 'visitor route'. I can't say I noticed any particular carvings on it just thinking it was part of a possible dolmen and rather more intent on taking in the breathtaking views. Did you pick up on anything yourself? I've mentioned before that I've never been a follower of rock art although appreciating it when obviously observed so it is not something I go out of my way to find. I'll go and wash my mouth out now!!
