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.
Gangotri Group The Gangotri Group of mountains is a subdivision of the Garhwal Himalaya in the northern Indian state of Uttarakhand. It rings the Gangotri Glacier, and contains peaks that are notable either for their religious significance to Hindus, for their difficult climbing routes, or both. Climbs on three of the peaks (Thalay Sagar, Shivling, and Meru) have resulted in the awarding of the prestigious (but controversial) climbing award, the Piolet d'Or.
