Chuscha, Cordillera de Catreal, Northern Andes, 1992. Argentines Pablo Sahade, Eduardo Arjona, leader Antonio Beorchia Nigris and Swiss Rafael Joliat ascended the Río Ovejeria and the Río Suri Ciénaga to reach this mountain, the highest in the range. On November 26, 1992 Beorchia and Joliat camped at 4600 meters. Early the next morning, they climbed the eastern slopes of Chuscha and then went west, climbing the five summits of the massif. Joliat climbed solo to the highest point (5512 meters, 18,084 feet), making the first modern ascent. There were pre-Columbian ruins on top and evidence of a sacrificed deer. (In the Ovejería valley, they saw an entire herd of sheep with four and even five horns.)
