Short summary
Eastern Alpine glaciers have been receding since the Little Ice Age maximum, but until now the majority of glacier margins could be delineated unambiguously. Today the outlines of totally debris-covered glacier ice are fuzzy and raise the discussion if these features are still glaciers. We investigated the fate of glacier remnants with high-resolution elevation models, analyzing also thickness changes in buried ice. In the past 13 years, the 46 glaciers of Silvretta lost one-third of their area.
