 They were carried down to the glacier by an avalanche but they survived the accident.On 9 August 1890, L. Norman-Neruda with guides Christian Klucker and J. Reinstadler were the first to reach the summit (Liskamm East) by the north face, by what is now known as the "Norman-Neruda route".The first winter ascent of this route was made on 11 March 1956 by C. Fosson and O. Frachey.
