Mountains in India
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 dOr.
