"It'd be useful to see more photos, especially some where the surface is wet."

Hob, and everyone who responded,

Thanks for your replies. I wish I could find more photos. The photo was posted on the UKClimbing website, and a search of that found no other photos of the rock art, but there were details of the crag. Also, a trawl of t'internet drew no other clues.

I suppose one of the great problems of rock art is the dating of it. How do you prove the age of a carving or chipping? For example, the Copt How rock art was claimed to be done by a bored climber from one of the local climbing huts on a particularly wet day (there are many wet days there), over 50 years ago.

Also, if someone wanted a good look at the rock art, then they'd probably (rightly or wrongly) give it a good scrub first.

Any opinions on these points?

Perhaps some TMA bod, living near Paleley Bridge could be so kind as to pop round for a gander?

Cheers,
TE.
