Chessjengletscher NW
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.
Chessjengletscher NW is one of 1,400 glaciers in Switzerland, covering 0.34 km² in the canton of Valais. Its ice spans 2,720 to 3,280 m and faces north. Its meltwater drains to the Rhône and on to the Mediterranean. In 1850 it was part of a larger ice body of 19.3 km², which has since split into 2 glaciers covering 14.2 km² in 2016 (−27%). Its mass balance has been measured since 2018: on average −1.17 m of water equivalent per year, with the most negative year in 2022 (−2.69 m). Between 2015 and 2023 its surface dropped by 9 m on average. No glacier model run exists for it; on the map it follows the typical path of glaciers its size.
The record
Mass balance 2018–2025
Ice gained (blue) or lost (red) over the whole glacier each year, in metres of water equivalent. Measured with stakes drilled into the ice.
Thinning since 2015
Average change in surface height, from comparing elevation models made from maps, aerial images and laser scans.
