In reply to JamieSparkes and Fiona Reid:
Hi Sorry it took a while, I was away. I don't have pics. When I climbed it I didn't feel any instability either. It was when I was standing on the small ledge at the top of Wally 1 just below the belay bolts and was clipped in. I was taking pictures of a 9 year boy climbing on a top rope. Every time the rope came under tension the whole top section of the crag/face would sway a few inches. It was very unnerving. It was NOT like standing on a wobbly chock stone or stone plinth that is just laying on its pivotal point; it was the whole top section of the face. It didn't rock from side to side, it swayed. Totally different sensation, probably, at a guess it was moving from where I was standing down to the first big horizontal crack, maybe 5 meters below. Given the reverse side of this face, near the Ratho building where they keep their maintenance vehicles and two containers, has fallen down in the last year or two and has had a Geological Survey conducted that concluded it was unsafe in that zone, it is perhaps not unreasonable to assume that the other side of this spur of rock that juts out from the main wall, is also unstable. Hope that helps.
