evidence: Kunlun Mountains, mountain system of southern Central Asia. The Kunluns extend west to east some 1,250 miles (2,000 km), from the Pamirs in Tajikistan in the west to the Kunlun Pass and the adjacent ranges of central Qinghai province in China in the east—Burhan Budai, Bayan Har, and A’nyêmaqên (Amne Machin). The width of the Kunluns varies considerably but rarely exceeds 125 miles (200 km). In the western margins they form an Inner Asian rampart between the Plateau of Tibet and the Tarim (Talimu) Basin in western China. A northern fork of the Altun (Altyn Tagh) Mountains continues this alignment. [...] Throughout much of their alignment, the Kunlun Mountains comprise two or three parallel ridges rather than a single crest. This is especially true in the western reaches. At the Sarykol Range where the Kunluns forge out from the Pamirs, a spur to the east called the Muztagata Range actually has some of the highest summits—Mount Kongur, at 25,325 feet (7,719 metres), as well as Mount Muztagata, at 24,757 feet (7,546 metres). A major bifurcation occurs just south of the oasis town of Qiemo (Cherchen); there, the Altun Mountains branch in a northeasterly direction from the Arkatag Mountains at Mount Muztag (Muztagh), which at 25,338 feet (7,723 metres) is the highest point in the Kunluns. To the east the northern rim of the Kunluns then becomes the southern margin of the vast, high Qaidam (Tsaidam) Basin. High valleys with occasional saline lakes intersperse the medial Kunlun ridges.
