I was one of a group who did an exchange on Friday evening, and we didn't have to do anything to get in, so maybe we followed someone else who did do some digging - it was open both ends. Not that there wasn't any snow left mind.
I went in the 'wet' route, which wasn't very wet at all, and derigged the dry route, which was hilarious and a little hairy. I've never been before, and so coming up into a giant cornice of snow on the exit pitch, having no idea at all what was underneath it (I'm guessing a boulder choke) was a bit of a 'gulp' moment, especially when I saw the rope was cutting a good 40cm into the snow. I managed to swipe the jammer sideways and chop a big slice of snow out, and just spread myself over the whole blob and climb messily up it.
Great quick trip though, apart from the subzero walk back.
