Ojos del Salado, Winter Ascent. W. Ritter, P. Stecher and I left Tinogasta in the Argentine on June 7 and headed on foot across the desert to the Ojos del Salado. On June 20 we left our Camp VI at 18,875 feet and in eight hours climbed the south face to the summit. There were UIAA Grade III to IV climbing difficulties just below the summit. The rock was very rotten and dangerous. We believe this was the tenth ascent of the mountain. We were back in Tinogasta after 17 days.
