  Title: Walter Bonatti
  Passage: Walter Bonatti (] ; 22 June 1930 in Bergamo – 13 September 2011 in Rome) was an Italian mountain climber, explorer and journalist.  He was noted for his many climbing achievements, including a solo climb of a new route on the south-west pillar of the Aiguille du Dru in August 1955, the first ascent of Gasherbrum IV in 1958 and in 1965 the first solo climb in winter of the North face of the Matterhorn on the mountain's centenary year of its first ascent.

  Title: Gasherbrum
  Passage: Gasherbrum (Urdu: گاشر برم‎ ) is a remote group of peaks located at the northeastern end of the Baltoro Glacier in the Karakoram range of the Himalaya on the border of the Chinese-administered Shaksgam Valley and the Gilgit-Baltistan territory of Pakistan.  The massif contains three of the world's 8,000 metre peaks (if Broad Peak is included).  Although the word "Gasherbrum" is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of Gasherbrum IV, it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain".

Gasherbrum I is part of the Gasherbrum massif, located in the Karakoram region of the Himalaya.  Gasherbrum is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of the neighboring peak Gasherbrum IV; but in fact it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain."
