Huayhuash Traverse Attempt. A very strong French team of leader René Desmaison, Michel Arizzi, Xaxier Chappaz, René Ghilini, Jacques Fouque and Christophe Profit had hoped to traverse the Cordillera Huayhuash from Rondoy over Jirishanca and other peaks to Yerupajá, more than 12 miles and of extreme difficulty at high altitudes. The plan was foiled by very bad weather. However, Desmaison, Ghilini and Profit did climb the west face of Yerupajá from 5100 meters in a single day.
