The crumbling of the rock mass produces a lot of dust. Picture: Felssturz am Eiger, Grindelwald (5), Eva Gertsch GIUB 23.06.2006

On 13 July the right side of the rock packet broke off in three stages. Around one fifth of the rock mass (460,000 cubic metres) collapsed onto the glacier. The earthquake service recorded tremors at 7.25, 7.26 and 7.39 p.m. Picture: Felssturz am Eiger, Grindelwald (2), Simone Hunziker, PLANAT BAFU 23.06.2006

The earthquake service recorded tremors at 7.25, 7.26 and 7.39 p.m. The heaps of rock that have already broken away from the rock can be seen in the photograph.

Eiger rockfall Madonna: this Madonna figure formed for a short time from the remaining rock after small mass movements on the eastern flank of the Eiger. On 13 July 2006, the rock broke off the right side of the eastern flank of the Eiger in three stages and collapsed onto the glacier.

Parts of the rock outcrop on the east face of the Eiger moved between 75 and 100 cm downwards and 25 cm forwards over a period of six days. A large crevice formed here as a result. Picture: Felssturz am Eiger, Grindelwald (6), Eva Gertsch GIUB 11.07.2006


The surface of the glacier in the vicinity of the glacier lake has sunk by over 200 m since 1860. The glacier tongue has retreated since then by around 1.6 km. Due to the lake of ice pressure on the rock face, a two million m3 chunk of rock worked itself loose and has attracted much attention in recent years due to the resulting spectacular rockfall events.

Following an increase in rockfall activity  in August 2008, only two columns of the former chunk of rock remain. These columns collapsed in summer 2009. The break-off point and the debris deposits are all that remain visible now from the path to the Bäregghütte mountain hut.
