Namtso was born in the Paleogene age，as a result of Himalayan tectonic plate movements.The lake lies at an elevation of 4，718 m，and has a surface area of 1，920 square kilometres.This salt lake is the largest lake in the Tibet Autonomous Region.However，it is not the largest lake in the Qinghai-Tibet Plateau.Namtso has 5 uninhabited islands of reasonable size，in addition to one or two rocky outcrops.
The islands have been used for spiritual retreat by pilgrims who walk over the lake’s frozen surface at the end of winter，carrying their food with them.They spend summer there，unable to return shore again until the water freezes the following winter.
