Huandoy Norte, East Face and Other Peaks, 1977. Bertl Gribnitz, Waltraut Sommersacher, Arnulf Leitner, Gerhard Neumayer and I as leader climbed in the Cordillera Blanca in July of 1977. On July 27 we repeated the Polish route on the east face of Huandoy Norte. (A.A.J., 1978, p. 565.) This took us 14 hours on the face. We climbed Huandoy Sur on the descent. We also climbed Yanaraju, Pisco, Yanapaccha Oeste by its west face, and Chopicalqui by the west ridge.
