In reply to Silverback38:
I once did Mam Torr Gully in good condition, best I'd ever seen in about half a dozen jaunts up it in winter conditions, so wandered round to Back Tor Gully expecting the snow to be spot on. It was absolute rubbish, nothing frozen and didn't improve with height, became rather exciting, not what I was expecting at all. Ah ! the fickleness of winter conditions.
