Wenquan, Golmud

Wenquan (, i.e. "Warm Springs") is a small settlement in the Qinghai province of China.
Administratively, it is part of Tanggula Town, which is an exclave of Golmud County-level city, Haixi Mongol and Tibetan Autonomous Prefecture.
Originally constructed in 1955, Wenquan is one of the small settlements serving China National Highway 109 (the main road into Tibet), and, later, the Qinghai-Tibet Railway.
Geography.
The settlement is located in the area where the highway and the railway cross the Tanggula Mountains, the mountain range in the center of the Qinghai-Tibet Plateau. It is located a few tens of kilometers north of the Tanggula Pass, where the road and the railway enter from Qinghai Province into the Tibetan Autonomous Region. It is one of the highest settlements in the world with residences up to above sea level.
Although not really a "city" by any definition, Wenquan is listed in the Guinness Book of World Records (misspelled as "Wenzhuan") as the world's highest city, with an incorrect elevation of above sea level. Travel books also inflate the size and elevation of this settlement. However, National Geographic Magazine (May 2003) gives the highest city distinction to La Rinconada, Peru, which has a much higher population and lies at above sea level.
Some 20–30 km to the north of Wenquan, in the same highway/railway corridor, detailed maps (e.g., on Google Maps) show Wenquan Military Station ().
According to bicycle tourists who visited the place in 2000, Wenquan, like other settlements in the region, was "small. Just a few buildings." There were indeed warm springs in the area. They described the location, based on their maps, as being "at 4,800+ metres" elevation, an elevation confirmed (at 4,850 to 4,870 meters) by SRTM data.
Climate.
Wenquan has a tundra climate (Köppen classification "ET") bordering very closely on a subarctic climate (Köppen classification "Dfc"). It has cool summers with some precipitation and cold, dry winters. The yearly precipitation is , which means Wenquan is technically in a desert. Due to its high elevation, there is high diurnal temperature variation.
