The East-Pamir, in the centre of which the massifs of Mustagh Ata (7620 m) and Kongur Tagh (Qungur Shan, 7578, 7628 or 7830 m) are situated, shows from the western margin of the Tarim Basin an east-west extension of c. 200 km. Its north-south extension from King Ata Tagh up to the northwest Kunlun foothills amounts to c.170 km. Whilst the up to 21 km long current valley glaciers are restricted to mountain massifs exceeding 5600 m in height, during the last glacial period the glacier ice covered the high plateau with its set-up highland relief, continuing west of Mustagh Ata and Kongur. From this glacier area an outlet glacier has flowed down to the north-east through the Gez valley up to c.1850 m asl (meters above sea level) and thus as far as to the margin of the Tarim basin. This outlet glacier received inflow from the Kaiayayilak glacier from the Kongur north flank. From the north-adjacent Kara Bak Tor (Chakragil, c. 6800 or 6694 m) massif, the Oytag valley glacier in the same exposition flowed also down up to c. 1850 m asl. At glacial times the glacier snowline
