Alpen-Panoramen, Panorama der Alpen

I republish the overview by adding a previous image to the first two, as I remembered I went to those places even a couple of years earlier. I think that this diachronic testimony is truly significant. Thanks to those who just voted my previous pano; I hope they will enjoy this one too...
In addition to the possibility of comparing three different photographic qualities (details below), this collage of images serves me to highlight the radical change of places and ascent conditions.
The first image is from August 2014; you can clearly see the snow-covered slope that leads to the foot of the Grosser Burgstall and thus to the path to the Oberwalderhütte without much thought. On August 2016 (second image) the amount of snow on the ramp had slightly decreased and the ice was almost completely uncovered but it was still easily passable. On that occasion I carried up my two sons who, even without having much experience of progression on ice and snow, made it without problems.
The image on the right is instead of this August (4 years later). Besides the overall shrinkage of the frozen surface (which can be understood much more dramatically by looking at the state of the Pasterze) the "snow gum" has totally disappeared and left uncovered a vast slope of unstable debris, quite tiring to climb. Grosser Burgstall looks like a huge tooth with the entire collar exposed. The hut is now reachable on the path with a not very easy ferrata ramp about which I do not think has been given news neither on the refuge website nor on that of the Alpenverein, and even at the Franz-Joseph Hohe there were no indications about the need to have the via ferrata set. Since I was accompanying a not very experienced person I preferred to give up the hut, but I was a bit angry for this lack of information (at least in the Italian mountaineering environment). Anyway the location is always amazing and awesome; for Eastern Italian Alps mountain lovers the Hohe Tauern are the closest place to breathe "high mountain air".
@ OeAV friends: do you have some notices and/or informations about the "new" access to Oberwalderhütte? Thanks in advance.
