In reply to Wildabeast:
I climbed it in 1963 via the Glocknerleitl after breakfast at the Erzh-Johann Hutte, having started from the Franz Joseph Hutte earlier that morning, and crossing the Franz Joseph Glacier and Hofmannskees Glacier which at the time was wet and heavily crevassed, followed by the rocky Salmkamp Ridge.
As we are talking about 54 years ago now a lot would have changed and my recollection is poor, but I remember it being a beautiful mountain and surprisingly the ridge and col from the Klein Glockner to the Grossglockner summit was free of ice and snow. We did it in a day descending again via the Glocknerleitl and then down to the Salmhutte via the Hohenwartscharte col, taking 11 hours in all.
