What is the highest peak in the Tien Shan mountain system?

Jengish Chokusu is the highest peak in the Tien Shan mountain system.

Also known as Victory Peak or Pobeda Peak, Jengish Chokusu reaches 7,439 metres on the China–Kyrgyzstan border. It belongs to the Kakshaal Too subrange and is both Kyrgyzstan’s highest mountain and one of Central Asia’s most formidable summits.

The mountain is a broad, heavily glaciated massif rather than a simple isolated pyramid. Its northern glaciers feed the South Engilchek Glacier, while climbers commonly approach the main summit via the Zvezdochka Glacier. The first ascent was achieved in 1956 by a Soviet expedition led by Vitaly Abalakov.

Khan Tengri is the usual source of confusion. Its dramatic marble pyramid was long thought to be the Tien Shan’s highest peak and remains the range’s second-highest mountain. Khan Tengri’s rock summit is 6,995 metres, although its ice cap lifts the mountaineering elevation to about 7,010 metres—still well below Jengish Chokusu.
