South America, Peru—Cordillera Huayhuash, Yerupajá Sur, Rasac, and Other Peaks

Yerupajá Sur, Rasac, and Other Peaks. A Swiss expedition led by Ernst Schmied unsuccessfully attempted Yerupajá but on June 13 Schmied with Hermann Steuri and Rudolf Debrunner reached the 21,375-foot south summit, which an Argentine and a previous Swiss expedition had climbed before. On June 20 Hanspeter Rychen and Theo Marti also reached this summit. Steuri and Erst Schill made the sixth ascent of Rasac (19,817 feet). Steuri alone made the first ascent of Rasac Central (5617 meters or 18,429 feet), which lies two kilometers northwest of Rasac, while Rasac Norte (17,220 feet), which lies another kilometer farther northwest, was climbed first by Schill and Jost Felber and later, on June 18, by Paul Roth alone. Debrunner, Roth and Schill made the first ascent of TAM Sur (5545 meters or 18,192 feet), which lies across the glacier about a kilometer west of Yerupajá Chico. On June 19 Roth alone made the first ascent of Huacrish Norte (5167 meters or 16,952 feet), which lies between the head of the east branch of Quebrada Huacrish and the Quebrada Rasac, and climbed previously ascended Jahua Este (16,523 feet), which lies two kilometers to the northwest.
