The ascent was made without the aid of supplementary oxygen.[5] The same day, three climbers from a different expedition — Austrian Gerfried Goschl, Swiss Cedric Hahlen and Pakistani Nisar Hussain Sadpara — went missing, never to be found again. They were trying to ascend via a new route and are considered to have been blown off by strong winds.[6] 2013 - 7 July, Artur Hajzer died after falling in the Japanese Coloir after an attempt to reach the summit.[9] 2013 - 21 July, Spaniards Abel Alonso, Xebi Gomez and Álvaro Paredes climbed to the top to then disappear while descending after a storm.[10] 2017 - 30 July, in an alpine style six-day ascent without supplementary oxygen, Czechs Marek 'Mára' Holeček and Zdeněk Hák established a new route named Satisfaction! (in memory of Zdeněk Hrubý) up the Southwest Face.[11]
