I went for a walk on Ingleborough today and came across a scaffolded shaft at the base of a reasonable-sized shakehole vaguely south of Hurnell Moss Pot. At any rate, it is the next good-sized shakehole beyond Hurnell Moss.
Looking in Northern Caves it appears the shake is probably Newby Moss Cave & Sink, although the description of what is there doesn't seem to match with what I found.
Anyone know anything about it? It seems to be being actively dug but in shorts and t-shirt with no light I couldn't really find out more than that. There was a tackle sack nearby with what seemed to be WCG on it ... but I don't know of a club with those initials.
