evidence: Sketch Map of Kula Kangri [...] On 21 April the assault party consisting of Itani, Sakamoto, Ozaki, and Ohtani, departed from C4 at 10.00 a.m. (Beijing time). The weather was fine, while it was very bad the day before. The temperature was about —30 °C. By negotiating the ice-slope of 40 degrees covered by a little snow, they reached the summit ridge at noon. From here the knife ridge continued to the summit. A huge cornice on the ridge threatened them. The wind was gentle. All members in BC, ABC, and other camps watched them and made contact by transceivers. At 4.15 p.m. they succeeded in reaching the summit of Kula Kangri, 7554 m. The summit was so small that two persons could not both stand on it at the same time. They stayed there about an hour. They enjoyed the splendid panorama. Especially the view of the Bhutan Himalaya including Gankerpun-sum (7541 m) could be seen. They returned back to C3 at 8.30 p.m. [...] Frontispiece: Kula Kangri from Tibet. (Prof K. Hirai)
