In reply to NickNixon:
Hey Nick, The last ascent on the Chamoniarde website (www.chamoniarde.com) was on the 27 of July (a bit old). That report described conditions as being good and metionned lots of snow. Obviously that's from a couple of weeks ago. The refuge du Couvercle website has an update from the 9th August saying it's "been done" also mentions that it's "moving a bit". Best idea is to call the Couvercle (refugeducouvercle.jimdo.com).
If you go and do it I'd be interested to hear how you get on. I'd like to have a crack at it myself but I can't get up there for a couple of weeks so I think it'll have to be next year.
