Dave, a quick glance at your 8-thousand-odd post tally tells me that you've got a lot of spare time on your hands (or at least you used to have in your old job).
Wow, you learn something everyday. The only rock art I knew about in the peak was the carved spirals/ cup-marks on grit.
In 2003, engravings were found on the walls and roofs of some of the caves - the only known examples of Palaeolithic cave art in Britain. Their subject matter is representations of animals including bison and several different bird species. The engravers seem to have made use of the naturally uneven cave surface in their carvings and it is likely that they relied on the early morning sunlight entering the caves to illuminate the art. Thin layers of calcium carbonate flowstone overlaying some of the engravings were dated using the uranium-series disequilibrium method, which showed the oldest of these flowstones to have formed 12,800 years ago. This provides a minimum age for the underlying engraving. The scientists and archaeologists concluded it was most likely the engravings were contemporary with evidence for occupation at the site during the late glacial interstadial at around 13,000-15,000 years ago.
I don't know if its already been covered in this thread, but has anyone checked out the crag with what looks like a large roof situated above beginners wall? Looked liked it had some potential for two or three bolt lines on it, although perhaps it was a lot smaller than it looked from the path leading up to beginners wall.
That reminds me. Last week I recieved a tender document on my desk for rock stabilisation work to Toad Hall!! Called Shacklow Wood in the doc, but it's definately the same thing. Not sure what if any implications this might have on the access situation. Passed the tender on to the guy who deals with rock work, but will try to get it back for a proper look.
