Nandakhani stands between Shalang Glacier on the eastern side and Pindari Glacier on the western side. On the southern side guards the Kafni Glacier. Shalang glacier flows from south-west to south-east and joins Goriganga River that later joins the Kali River at Jauljibi. On the southern side from Kafni glacier emerges Kafni river and after a short run it joins Pindari river at Dwali. On the western side Pindari Glacier flows down from north to south and from the snout of Pindari glacier emerges Pindari River that later joins Alaknanda at Karnaprayag. Alaknanda River is one of the main tributaries of river Ganga that later joins Bhagirathi River the other main tributaries of river Ganga at Devprayag and became Ganga there after.
