As part of this year's PhD students workshop at the research station "Schneefernenerhaus", Professor Senner and his scientific collaborators Aljoscha Hermann and Philipp Kopp used the great opportunity to climb up the Zugspitze (the highest German Mountain) on the most beautiful, but at the same time most challenging tour through the "Höllental". A unique and great tour over about 2200 vertical meters, which was rounded off by a successful workshop.
