Santa Rosa, West Face, Cordillera Raura. On June 28 Bernard Francou and I climbed for the first time the west face of Santa Rosa (5706 meters, 18,721 feet). The 1650-foot high face, which varied from 50° to 65°, took us five hours to climb. We crossed a crevassed area and attacked the very center of the wall. We climbed a long couloir to the left of the large, smooth rock rib to a wall of séracs, where we turned left to reach the summit triangle.
