Ulvetanna Peak (Norwegian: the wolf’s tooth, German Matterhorn) is a sharp peak (2,930 m) in Queen Maud Land, Antarctica. It was first climbed in February 1994. The mountain was first discovered by the German Artic expedition in 1938 and named after the Swiss mountain Matterhorn because of his similar form. Later the mountain was renamed by the Norwegians in Ulvetanna Peak.
Ulvetanna lies about 2 miles (3.2 km) north of Kinntanna Peak in the Fenriskjeften Mountain (Norwegian: Fenrir’s maw) in the east part of Queen Maud Land, Antarctica. The peak is one of the most demanding on the continent and its mile-long north east ridge has been described as one of “the last great climbs”. Mapped from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named Ulvetanna.
