Kunlun Mountains

The Kunlun Mountains constitute one of the longest mountain chains in Asia, extending for more than . In the broadest sense, the chain forms the northern edge of the Tibetan Plateau south of the Tarim Basin. The exact definition of Kunlun Mountains varies over time. Older sources used Kunlun to mean the mountain belt that runs across the center of China, that is, Altyn Tagh along with the Qilian and Qin Mountains. Recent sources have the Kunlun range forming most of the south side of the Tarim Basin and then continuing east, south of the Altyn Tagh. Sima Qian (Records of the Grand Historian, scroll 123) says that Emperor Wu of Han sent men to find the source of the Yellow River and gave the name Kunlun to the mountains at its source. The name seems to have originated as a semi-mythical location in the classical Chinese text Classic of Mountains and Seas. From the Pamirs of Tajikistan, the Kunlun Mountains run east through southern Xinjiang to Qinghai province. They stretch along the southern edge of what is now called the Tarim Basin, the infamous Taklamakan desert, and the Gobi Desert. A number of important rivers flow from the range including the Karakash River ('Black Jade River') and the Yurungkash River ('White Jade River'), which flow through the Khotan Oasis into the Taklamakan Desert. To the south of the Kunlun is the sparsely populated Changtang region, which forms part of the Tibetan Plateau. Altyn-Tagh or Altun Range is one of the chief northern ranges of the Kunlun. Its northeastern extension Qilian Shan is another main northern range of the Kunlun. In the south main extension is the Min Shan. Bayan Har Mountains, a southern branch of the Kunlun Mountains, forms the watershed between the catchment basins of China's two longest rivers, the Yangtze River and the Yellow River. The highest mountain of the Kunlun Mountains is the Kunlun Goddess Peak (7,167 m) in the Keriya area of the western Kunlun Mountains. Some authorities claim that the Kunlun extends further northwest-wards as far as Kongur Tagh (7,649 m) and the famous Muztagh Ata (7,546 m).
