Huayna Potosí. Michiko Sekita, Fusako Shimizu and Masako Abe, all women, climbed in the Cordillera Real. For acclimatization, on June 18 they all climbed a nameless 17,400-foot peak, attempted Wila Llojeta (17,205 feet) the next day and on the 22nd climbed Cerro Jachichapata (17,782 feet). On July 1 they moved to camp at 16,000 feet at the foot of Huayna Potosí, camped on the 3rd at 18,700 feet and on July 4 climbed to the highest peak (Ccaca Aca, 19,994 feet). Their attempt on Illimani failed at about 19,000 feet when Miss Shimizu became ill.
