Mount Kazbek
On 10 April 2015 Koblmueller led a group of nine participants in a ski expedition to Mount Kazbek (5047 m/16,516 ft) in the Greater Caucasus. During one leg of the ascent the group encountered a snow storm. Seven members of the mostly Austrian group managed to reach a hut and were unharmed. As guide, Koblmueller aided a 59-year-old Austrian participant. Both were caught in a blizzard, and were found on the afternoon of 16 April 2015 at an altitude of 4700 m having died of hypothermia. Their bodies were retrieved by helicopter.
