In reply to Pepper:
Well, I don't have any great knowledge of the place except what's in the PDF by Tony Howard et al., but I shall try to remember to use that information to add the crag to UKC next time we have a spell of rainy weather when I've got nothing better to do.
It's not a great place, but it's worth a visit and a lot better than some of the appalling holes in the ground that are included in the Lancashire guide.
