The Tso Kar, known for its size and depth, is a fluctuating salt lake situated in Rapshu in the southern part of Ladakh. Until a few years ago the lake was an important source of salt, which the Changpa nomads used to export to Tibet. It is at a height of 4500 mtrs. (14763 ft.) above sea level.
Kar means "White" and it gets its name because of dominant white patches of salt seen all around this beautiful lake.
