South America, Peru, Cordillera Blanca, Ishinca, Ranracalca, Urus Oeste

Ishinca, Ranrapalca, Urus Oeste, Cordillera Blanca. Our expedition consisted of Hans Grimm, Fritz Luchsinger, Walter Amstutz, Andreas Zimmerli and myself. On June 26 we climbed Ishinca (18,143 feet), Ranrapalca (20,217 feet) on June 28 and Urus Oeste (17,881 feet) on July 4. Our attempt on Tocllaraju failed because of bad weather. Ernst Meyer and Wilfred Naegli also accompanied us on conditioning walks.
