With my friend Bernard. Climbed from the Felix Faure Hut. On the summit at 9h. The glacier melts more and more. The Grands Couloirs becomes steeper(40°)
Went off and climbed this solo, on ski's for 1st 1500m, up from the valley bottom, then parked the ski's to climb the steep snow slope up to the top. Fantastic experience!
Ski ascent of La Grande Casse in 2 days
We climbed up the Messimy Couloir on nice compact snow (thin crust in some places but good overall refreeze). From the Pointe Mathews, I skied down the Grands Couloirs while my partner went down the Messimy Couloir (although he had better snow, it was too much exposure for me)
Very nice trip: great weather and fantastic partners.
