one of the world's tallest mountains, 26,660 feet (8,126 metres) high, situated in the western Himalayas 17 miles (27 km) west-southwest of Astor, in the Pakistani-administered sector of the Kashmir region. The mountain's steep south wall rises nearly 15,000 feet (4,600 metres) above the valley immediately below, and the north side drops about 23,000 feet (7,000 metres) to the Indus River.

The British Alpine climber Albert F. Mummery (Mummery, Albert Frederick) led the first attempt to ascend the glacier- and snow-covered mountain in 1895, but he died in the attempt. At least 30 more climbers (mostly German-led) also perished on Nanga Parbat because of the severe weather conditions and frequent avalanches before the Austrian climber Hermann Buhl reached the top in 1953. The Kashmiri name Nanga Parbat is derived from the Sanskrit words nagna parvata, meaning “naked mountain.” Diamir is a local name for the peak and means “king of the mountains.”
