Aconcagua, South Face, Winter Solo, 1986. Spaniard Fernando Ruiz made the second winter ascent of the south face of Aconcagua solo in alpine style. At the beginning of September, 1986, he made a first attempt with Antonio de Lorenzo, but they were turned back by the weather at 5000 meters. On September 8, he set out again solo on the 1954 French route with the Messner finish. After five-and-a-half days he reached the summit on September 13. The descent was a nightmare. He spent a frightful night in the Independencia Hut and seven nights in the Berlin Hut, awaiting better weather. He finally made it back to Puente del Inca on September 22, but with seriously frozen hands and feet.
