Altar Group and Cayambe. An expedition from Waseda University was led by Junji Miyano. On June 28 Tadashi Hayakawa and Takeo Tsunoda reached the summit of Obispo (17,454 feet), the highest in the Altar group. When they reached the upper part of the final rock tower, they found a piton which was perhaps driven by the Italians. (Although the Japanese have claimed this as a first ascent, the Italians Tremonti, Gaspard and Zardini made the ascent in 1963. — Editor.) From July 21 to 24, they climbed the main peak of Cayambe (18,993 feet), a sixth ascent, and second (18,950 feet) and the third (18,765 feet) peaks, both first ascents. Some topographical and meteorological surveys were done after their climbing activities. The other members were Susumu Murata, Kazutaka Aoki and Keinosuke Matsumura.
