Matterhorn

Matterhorn, peak of the Alps in south-western Switzerland, near the border with the Italian region of Valle d'Aosta. It rises to an elevation of 4,478 m (14,692 ft). In July 1865 a group led by British alpinist Edward Whymper was the first to scale the famous jagged peak. It is an example of a pyramidal peak, where glacier-forming basins have eroded the rock on three or four sides of the massif, leaving only a pyramid-shaped core in the middle.
