The Trift Glacier () is a long glacier (2005) in the Urner Alps near Gadmen, in the extreme east of the canton Berne in Switzerland.
Morphology
In 1973 glacier was 5.75 km long, 3 km wide at the top and around 500 m wide at it tongue. Overall it covered an area of including glacier sides.
Since the end of the Little Ice Age, the Trift Glacier is shrinking. The valley in which lake Triftsee is today used to be filled by a large mass of ice well into the 20th century. In the 1990s small puddles of melt water began to form at the glacier tongue and gradually became larger. In the hot summer of 2003, the lake quickly grew and the glacier tongue sank into the melt water and dissolved in it, which led to a shrinkage of the glacier of more than 136 m within a year. From 1861 to 2021, the glacier shrunk a total of 3941 meters.
Tourist attractions
At an altitude of 2520 meters above sea level is the Trifthutte , a mountain hut of the Schweizer Alpen-Club (SAC) that was only accessible via the glacier tongue. Due to the melting of the glacier, in 2004 people were forced to build a bridge, the Triftbrücke to reach this hut.
