Eiger Glacier
The Eiger Glacier is a glacier situated on the northwest side of the Eiger in the Bernese Alps of Switzerland, within the municipality of Lauterbrunnen in the canton of Bern. It extends from a height of above sea level behind the Little Eiger, a secondary peak to the west of the Eiger, and runs toward the valley in the direction of the Eigergletscher railway station. Another tongue, at above sea level, is in the form of a hanging glacier between the Eiger and Little Eiger.
The glacier is long, with an area of, reduced from an area of recorded in 1973. From 1993 to 2017, it retreated by around as the glacier melted.
History
In 1990, a large, continuous crack was discovered during a helicopter flight, leading the to begin research to better understand hanging glaciers and develop measures to protect the Jungfrau railway station. The threatened collapse occurred later that year, but without causing any damage. Since then, an automatic camera has taken a photo of the glacier every day.In 2017, researchers from the University of Bern used detectors in the Jungfrau railway tunnel to produce 3D imaging of the Eiger Glacier’s firn layer, reaching depths of up to 80 metres. A study published in Geophysical Research Letters found that the glacier’s movement parallel to steep rock faces had caused lateral erosion. The researchers noted that continued monitoring is important, as receding ice may increase rockfall risk in an area with tourist facilities and a research station.
