Jengish Chokusu (, , ; , ; , Pik Pobedy, ) is the highest mountain in the Tian Shan mountain system at . It lies on the Kyrgyzstan–China border between the Ak-Suu District, in the Issyk-Kul Region of far Eastern Kyrgyzstan and Wensu County, Xinjiang, China. It is part of the Kakshaal Too, the highest part of the Tian Shan and located southeast of lake Issyk Kul. Names The mountain's official name in Kyrgyz is Jengish Chokusu, which means "Victory Peak"; its Russian name is Pik Pobedy (or Pobeda Peak) meaning the same. In Uyghur, it is called Tömür, meaning 'iron,' which is also the official name of the mountain in China. The Chinese name Tuōmù'ěr Fēng () is a phoneticization of the Uighur tomur and the Chinese feng meaning 'peak'. Description Jengish Chokusu is a massif, with several summits along its lengthy ridge. Only its main summit breaks 7,000 m. It is located southwest of Khan Tengri (7,010 m / 22,998 ft), separated by the South Engilchek glacier, where base camps for both mountains are usually located. The massif runs at right angles to the glaciers which flow from it into three alpine valleys in Kyrgyzstan on the north, all eventually running to the Engilchek Glacier, the largest in the Tian Shan. Its main summit is usually approached from the Zvozdochka (Russian for "little star") glacier, which is coloured red with rocks from Jengish Chokusu. Administratively, the Kyrgyzstan side of the mountain is in the Ak-Suu District of Issyk-Kul Region and the Chinese side, in Wensu County of the Aksu Prefecture of Xinjiang Uyghur Autonomous Region. Records Jengish Chokusu is the highest mountain in Kyrgyzstan. Jengish Chokusu is considered the most northerly 7,000-metre mountain in the world by geologists; the actual rock summit of Khan Tengri, the Tian Shan's third highest peak, is 6,995m above sea level, though a thick layer of ice adds another 15m to its altitude, such that mountaineers classify it as a 7,000m peak. The South Engilchek Glacier and its side glaciers occupy the entire north side of Peak Jengish Chokusu. This glacier, currently at 60.5 km in length, is the sixth longest outside of the world's polar regions. History Although Jengish Chokusu is over 400 metres higher, Khan Tengri was believed to be the highest peak in the range until Jengish Chokusu's survey in 1943.[4] A Soviet expedition mounted in 1938 to mark the
