The Eiger is a 3970 metres (13,020 ft) mountain in the Bernese Alps in Switzerland. It is the easternmost peak of a ridge crest that extends across the Mönch to the Jungfrau at 4,158 m. The northern side of the mountain rises about 3,000 m (9,800 ft) above Grindelwald and other inhabited valleys of the Bernese Oberland, and the southern side faces the deeply glaciated region of the Jungfrau-Aletsch, covered by some of the largest glaciers in the Alps.
