In reply to kenneM:
Was in yesterday. The main corrie was pretty buried in fresh snow, lots more than I'd expected. Many cornices, and some fairly big recent avalanches. We didn't want to venture near any of it.
By contrast the far left of the Southern Sector was totally scoured, everything left of Perseverance Wall was barely white at all, not in nick by any stretch.
The only section of Perseverance Wall not threatened by large cornices was the Perseverance Rib area. Looked pretty much the only sensible option in the corrie on the day. We did some combination of Perseverance Rib and The Vice, I'm still not clear which bits of which, but it was good.
It was thawing late afternoon on the walk-out. If it's warm up there today I'd guess there'll be a fair amount of stuff on the move. Wait for a good thaw/freeze before you go near any of the gullies
