The Eiger Glacier (German: Eigergletscher) is a glacier situated on the north-west side of the Eiger in the Bernese Alps of Switzerland, within the municipality of Lauterbrunnen in the canton of Bern.
[1] It extends from a height of 3,700 m (12,100 ft) above sea level behind the Little Eiger, a secondary peak to the west of the Eiger, and runs towards the valley in the direction of the Eigergletscher railway station.
[2] In 1990, a large, continuous crack was discovered during a helicopter flight, leading the Research Institute for Hydraulic Engineering, Hydrology and Glaciology at ETH Zurich [de] to begin research work, to gain knowledge about hanging glaciers and develop measures to protect the Jungfrau railway station.
The threatened collapse occurred in 1990, but without causing any damage.
Since then an automatic camera has taken a photo of the glacier every day.
