Huandoy Oeste, West Ridge. A French expedition completed the first ascent of the west ridge of Huandoy Oeste (20,853 feet) on August 6, 1974. The climbers were J.-L. Guyonneau, J.-L. Joubert, V. Lant, G. Lemoine and A. Zagdoun. They ascended the Rajururi but then climbed to the left out of the valley to reach the ridge, which lies to the left of the south buttress route done by the Poles in 1973. This long and difficult snow and ice ridge was defended at the base by a 350-foot rock wall and ended with a 800-foot rock step. They placed some 4000 feet of fixed rope and established three high camps.
