Unsuccessful. We have stopped at the summit of Petit Mont Blanc and decided the bergschrund might be too difficult to negotiate. Probably too late in the season. Will come back...
Ascension made in one day. Due to some job reason, we had not time enough. The conditions of the glacier were quite bad. Very hot temperature. We were stoped around 3500m. No chaces to continue.
Anyway in case of better condition and earlier start, the ascent in one day is feasible.
