In June 1978, Patrick Vallençant made the first ski descent of the southeast face of Artesonjaru in Peru, in the Cordillera Blanca, 6,000 meters above sea level and 60° of slope. He left Huaraz on horseback, a donkey carrying his equipment. While crossing Cajas, the last village on the trail to Lake Paron, he was greeted by Victor and Cesar, two Indians who accompanied him to the lake. The climb to the summit was tiring, requiring as much effort from his arms as from his legs. The beginning of the descent was hesitant, the slope extremely steep. He achieved his feat on June 9, his thirty-second birthday.
