Looks like A****** at the top of Mallerstang? I've climbed in the gorge (big wall on the right) and scrambled up this in a wetsuit - there are some 'interesting' caves in the vicinity.

That's the one. Too wet for climbing at the moment, andf given the volume of water coming down it's unlikely to freeze properly before the thaw. We found a nice icy chimney that give a good short pitch though.
We'd wondered about rock climbing but assumed it would be too loose.
