The Gangotri Group of mountains is a subdivision of the Garhwal Himalaya in the northern Indian state of Uttarakhand.
Bhagirathi I: 6,856 metres (22,493 ft); II: 6,512 metres (21,365 ft); III: 6,454 m (21,175 ft)], peaks with moderate routes on the back sides, but huge steep-to-overhanging cliffs on the side facing the glacier. Bhagirathi III, in particular, has seen some of the most extreme rock climbing in the Himalaya.
