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.
Eastern South Asia Eastern South Asia is a subregion of South Asia. It includes the countries of Bangladesh, Bhutan, India (specifically east India and northeast India), and Nepal. Geographically, it lies between the Eastern Himalayas and the Bay of Bengal. Two of the world's largest rivers, the Ganges and the Brahmaputra, flow into the sea through Eastern South Asia. The region includes the world's highest mountainous terrain and the world's largest delta, and has a climate ranging from alpine and subalpine to subtropical and tropical. Since Nepal, Bhutan, and northeast India are landlocked, the coastlines of Bangladesh and East India serve as the principal gateways to the region.
