In reply to posters:
Yes, the ascent was just over four months from breaking my ankle, and less that two months from when I was able to walk. Although I've still got a limp, two things made it possible. 1) Ski poles to cushion the descents and help make my foot placements solid and secure, and 2) large amounts of Ibuprofen. And if I'm really confessing, also a tiny rucksack, so that one of my mates always carried the rope!
Needless to say, this was an Alps trip with minimal prior training - over the previous four months I'd managed to ride to and from work one day and a five mile walk along the top of Stanage. Not very textbook, although a couple of training routes out from the Couvercle Hut got things moving again and provided acclimatisation.
The Berangere glacier is pretty small at the moment. It had a little snow on it, so the crampons bit reassuringly. But it wasn't steep or crevassed on the LH-side so passed in a matter of minutes.
Ahh, the Frontier Ridge to Maudit! Yes, we considered doing the route this visit, but the staff in the OHM advised against it. They said that it was really a route for times when there was a proper overnight freeze, since this provided protection from stonefall in the upper sections of the climb. From the OHM cahier des courses, it's clear that lots of people have made ascents very recently, but I'm increasingly out of the game of courting bad luck...
