Ninashanca, Northwest Face, and Seria Sur, West Face. A Polish expedition from Gliwice made a dozen ascents in the Cordillera Huay-huash. On June 30 Janusz Baranek and Andrzej Czok climbed the 1000-foot west face of Seria Sur (5230 meters, 17,159 feet). On July 16 Janusz, Baranek and Czok climbed the 2800-foot-high northwest face of Ninashanca (5637 meters, 18,494 feet). This was a difficult route on partially rotten rock with one rope-length of UIAA difficulty of VI-and a number of V. The route ascended to the right of the middle of the face and ended with four pitches of ice.
