I think the normal route from biv.Gervasutti could be rated F/PD only in the past when the Frebouze glacier was bigger.
Now the acces to the rocky cliff below the summit, is difficult; along steep ice slope (45°) in the begin and than on not easy slick rocks, covered of sand.
This is why our ascent stopped there...more or less 150m below the summit.
"Got tight last night on absinthe and did knife tricks. Great success shooting the knife into the piano. The woodworms are so bad and eat hell out of all furniture that you can always claim the woodworms did it."
