Cheers Rhiannon,
I've really got to heap lots of praise upon that seasoned hunter of rock art ,Tim Laurie for bringing the site to the attention of the rock art community and then equal praise to the tenacious Mr Rockrich for tracking the site down and posting it up.
I must confess, that I went up there with a notion that the carvings may have been the creation of William Danby and his men but came away with the opinion that the site is pretty much 'the real deal'.

"I feel agrieved that when I was there years ago I knew nothing about the rocks".
Don't worry Rhiannon, the carvings and all of the other lovely sites in the Dales will stil be there when you come back up north and I can almost guarantee that you will have the place to yourself.
cheers
