Steilimigletscher

IceIce lost since 1850This glacier

Past extents come from the Swiss Glacier Inventories of 1850, 1931, 1973 and 2016. Future extents are illustrative: each glacier’s projected area (OGGM, median of CMIP6 climate models) is removed from its lowest ice upward. About the scenarios. This glacier has no model run of its own; its future follows the typical path of glaciers its size.

Steilimigletscher is one of 1,400 glaciers in Switzerland, covering 1.47 km² in the canton of Bern. Its ice spans 2,104 to 3,322 m and faces north. Its meltwater drains to the Rhine and on to the North Sea. In 1850 it was part of a larger ice body of 11.3 km², which has since split into 2 glaciers covering 7.0 km² in 2016 (−38%). Its tongue has been measured 56 times since 1961. In total it has retreated 1,566 m, about 27.0 m a year. Between 1980 and 2024 its surface dropped by 26 m on average. No glacier model run exists for it; on the map it follows the typical path of glaciers its size.
