Illimani, North Ridge and Tiquimani, West Ridge, Cordillera Real. Phillip Stuart Dawson and I climbed the north ridge of Illimani in five days (from September 20 to 24, 1976) of atrocious weather. We have since discovered that Italians made the ascent of this ridge in early July. After recovering from minor frostbite, we climbed the west ridge of Tiquimani in two days, getting to the top on October 5. It was a good rock climb with an icy, gendarmed summit ridge. We descended the standard north face route.
