In reply to ClimberEd:
Hi Ed,
There's been a lot of change over the past decade, much of which has already been mentioned, but in case useful:
- Rond / Cosmiques
Wouldn't say there have been any major changes, though the glacial traverse back round to the Plan / Para face does feel like it's more crevassed than it used to be. There have been cases of people taking falls into some rather large slots, particularly early season or in poor vis, so one to be a little wary of.
- Midi / Plan routes
The plan trees are still skiing as they always have, but sadly is a less reliable destination than it used to be due to the higher rain-snow limits we've had in recent years and as a consequence the higher snowline. When conditions are good, the skiing is as good as it always has been, but the lower part can often result in some battered ski bases and a bit of a walk.
In terms of skiing off the Midi, all itineraries have become increasingly crevassed. Be very wary in the early part of the season. Some itineraries that used to be quite simple (e.g. Petit Envers, Grand Envers) are increasingly technical and open as a result of glacial change. The Requin exit couloirs are not in condition as often as they used to be, again due to the changing climate, and the same for the usual lefthand exit out of the Grand Envers. It's therefore increasingly common to have to finish via the normal VB exit, which again is more crevassed than it used to be, but generally fine with a clear track going through it.
- Berrard valley
Still skiing well!
- Pas d'chevre
Rarely ever skied now due to the demise of the exit gully, which is nearly always a rubble strewn mess. Folk are still skiing this area, but generally its with a lightweight paraglider to fly out (!) or by skining back up. As others have mentioned, the top telepherique is no longer in operation due to a fire. Therefore to access this area, and the wider Argentiere basin, people are skining up to the Col des Rachasses, either from the top of Bochard (less vert) or Herse (more direct).
Hope the above is all useful. It perhaps paints a slightly negative picture of the state of the glaciers/conditions, but there's still amazing skiing to be had. For the most part it's more that some lines are less reliable and/or need more care than they did 20 years ago.
Feel free to send us a message if you want up-to-date conditions info when you head out. I'm based out of the valley and will be ski guiding all winter so should have a reasonable overview of things. We've had the snowiest start to the winter that I've ever experienced with three weeks of near continuous precipitation, so hopefully it will be a good one!
