Explanation:

River Pushpawati flows through the Valley of Flowers in Chamoli district in Garhwal region of the Indian state of Uttarakhand.The Pushpawati rises from the East Kamet Glacier, near Rataban, at the base of the Himalayas near the central part of the Garhwal-Tibet border. It flows in a southerly direction to join the Bhyundar Ganga near Ghagharia. The combined stream is thereafter known as the Lakshman Ganga. The latter merges with the Alaknanda River at Govindghat. 

The glaciated upper valley of the Pushawati is U-shaped. The river flows past thick glacial deposits. A number of glacier-fed streams join it in its upper reaches. It flows through a gorge in its lower reaches. The upper tracts are under permanent cover of snow. Alpine, sub-alpine and temperate vegetation is there in the middle and lower catchments of the river. Human habitation is very sparse.
