Pethangtse, Barun Glacier. The Rikkyo University expedition from Tokyo under the leadership of Hirotoshi Fukuda attempted Baruntse (23,688 feet) four times between April 29 and May 9, but the highest they reached was still 150 feet below the summit; they were blocked off by the huge snow cornice. This was also the case on Pyramid Peak (22,430 feet), northeast of Chamlang, where Takeshi Kishino and Yasuji Endo were defeated at the altitude of 22,300 feet. Their only successful climbing was the fourth or fifth ascent of Pethangtse (22,080 feet) on May 16 by Takeo Yamanoi, Masami Okura and two Sherpas.
