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.
Mount Gongga Mount Gongga (), also known as Minya Konka (Khams Tibetan pinyin: "Mi'nyâg Gong'ga Riwo"), is the highest mountain in Sichuan province, China. It is also known to locals as "The King of Sichuan Mountains". Situated in the Daxue Shan mountain range, between Dadu River and Yalong River, part of the Hengduan mountainous region, Mount Gongga is the easternmost 7000 m peak in the world and the third highest peak outside of the Himalaya/Karakoram, after Tirich Mir and Kongur Tagh.
