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.
