The mountain has gained a reputation for seriousness because of the many cornices lying on the ridge and the frequent avalanches, thus leading to its nickname the Menschenfresser ("people eater").

The northern side of the mountain is an impressive 1,100 metres (3,600 ft) ice-covered wall, rising up from the Grenzgletscher.

The eastern and higher of the two peaks is 4,532 m, and was first ascended in 1861 from the Lisjoch up the east ridge by a 14-man team (seven Englishmen, one Scotsman, and six Swiss guides) led by J. F. Hardy and including William Edward Hall.

[5] The ridge as a whole (as well as the western summit) was first traversed three years later by Leslie Stephen, Edward N. Buxton, Jakob Anderegg and Franz Biener.

Young, who was very disappointed, convinced him to go back by the Lisjoch before descending to Zermatt, implying a second traverse on the Lyskamm.

The mountain is often climbed as a traverse from the Feliksjoch (West), to the Lisjoch (East) or vice versa.
