To which mountain range belong both Istor-o-Nal in the Hindu Kush and Mount Everest in Nepal and Tibet?
Istor-o-Nal Istor-o-Nal or इस्तोर-ओ-नल is the third highest mountain in the Hindu Kush, in the Chitral District of the North-West Frontier Province of Pakistan. It is the 68th highest independent peak in the world. It crowns a massif with eleven peaks of elevation more than 7000 m . The peak is located a few kilometres northeast of Tirich Mir (the highest mountain in the Hindu Kush), across the Tirich Glacier. Because Istor-o-Nal is behind the higher peak of Tirich Mir from many viewpoints, it is not easily visible and therefore not well known.
Noijin Kangsang Noijin Kangsang (, also Norin Kang or Noijinkangsang) is the highest peak of Lhagoi Kangri mountain range in the Tibet Autonomous Region in China. It lies between the Yarlung Tsangpo River (to the north), Yamdrok Lake (to the east) and the Himalayas mountain range (to the south).
