Geographics and Introduction: 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 (15,479 ft), and has a surface area of 1,920 km2 (740 sq mi). This salt lake is the largest lake in the Tibet Autonomous Region. However, it is not the largest lake on the Qinghai-Tibet Plateau. That title belongs to Qinghai Lake (more than twice the size of Namtso); which lies more than 1,000 km (620 mi) to the north-east in Qinghai.
Namtso has five 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 the summer there, unable to return to shore again until the water freezes the following winter. This practice is no longer permitted by Chinese authorities.
The largest of the islands is in the north-west corner of the lake, and is about 2,100 m (6,900 ft) long and 800 m (2,600 ft) wide, rising to just over 100 m (330 ft) in the middle. At its closest point it is about 3.1 km (1.9 mi) from the shore.
The most remote island is, at its closest, 5.1 km (3.2 mi) from the shore. At summer time birds like Ruddy shelduck Phalacrocorax migrate to the lake area, besides the fields of astragalus, roegneria nutans and marram grass.
The weather at Namtso is subject to abrupt sudden change and snowstorms are very common across the Nyainqêntanglha range.
