Chacraraju

Chacraraju or Chakraraju is a mountain in the Cordillera Blanca range in the Andes of Peru. The mountain has two distinctive peaks: Chacraraju Oeste and Chacraraju Este. Chacraraju is located in Huaylas Province, Ancash; south and southeast of Pirámide and east of Lake Parón. The peak is accessible from the Pisco base camp at Cebollapampa.
Chacraraju is considered the steepest and the most difficult-to-climb six-thousander in the Andes. A French expedition led by Lionel Terray first climbed the mountain on 31 July 1956 and on 5 August 1962 using what have since become the normal routes. Greg Mortimer was badly injured during a later attempt to climb the mountain.
