In reply to ridgback:
We were up on Nevis yesterday. Only really the large easy gullies looked complete (we saw No's 2,3,4 & 5). The snowpack starts just short of where the climbs start.
We ended up going for no 2 gully as it lookes the best; but I'm sure grade II gullies don't usually have a bergscrund or crevaces? Although the snowpack was generally nice and solid and minimal snow/rock fall, the ice falls were running with water and it was raining on the summit. It wouldnt surprise me if the cornice collased last night as it looked fairly cracked up?
It's already been said though, it's getting colder midweek (hopefully), so the damp snow might consolidate really nicely? Good luck with it!
