Nanga Parbat, locally known as Diamer, is the ninth highest mountain in the world at 8,126 metres (26,660 ft) above sea level. Located in the Diamer District of Pakistan’s Gilgit Baltistan region, Nanga Parbat is the western anchor of the Himalayas. The name Nanga Parbat is derived from the Sanskrit words nagna and parvata which together mean “Naked Mountain”. The mountain is locally known by its Tibetan name Diamer or Deo Mir, meaning “huge mountain”. An immense, dramatic peak rising far above its surrounding terrain, Nanga Parbat is also a notoriously difficult climb. Numerous mountaineering deaths in the mid and early-20th century lent it the nickname “Killer Mountain.”

Nanga Parbat was first climbed, via the Rakhiot Flank (East Ridge), on July 3, 1953 by Austrian climber Hermann Buhl, a member of a German-Austrian team. Nanga Parbat was first successfully climbed in winter on February 26, 2016, by a team consisting of Ali Sadpara, Alex Txikon, and Simone Moro.
