for adding in - you did it as a ski tour, I suppose?
yes but I did not climb Fliana with ski - we were on route from Silvretta huts to Piz Buin. The we took downhill to Tuoi hut. From Plan di Mezdi we climbed half an hour in direction to Piz Fliana for a nice powder downhill. The further track to the summit looked steep and very demanding.
I've just noticed your downhill pic. It's curious - my impression was that from Plan Mezdi the 1st part of the glacier is the steep and demanding one while higher up near the ridge it becomes flatter and more comfortable, and I assumed that the downhill pic has been taken there.
