The Hallstätter Glacier (German: Hallstätter Gletscher) (formerly also called the Karleisfeld or Karl Icefield) is the largest glacier in the Dachstein Mountains. It lies immediately beneath the northern foot of the Dachstein itself and runs down to the Eissee lake below the Simony Hut at a height of 2,205 m. To the east the Hallstätter Glacier is bounded by the High Gjaidstein. Firmly sealed off at its western snout by the Schöberl, 2,426 m, it is bordered in the west by the eastern flank of the Hohes Kreuz ridge, running from south to north, which reaches a height of 2,837 metres. In its upper third the glacier flows around a prominent landmark, the Eisstein. At its head in the south it is also bordered by the Hunerkogel and the Dirndln.
