Cerro Arenal and Other Ascents, 1991. In the Olivares group, west of the city of San Juan, on August 8, 1991 Humberto Campodónico made solo the first winter ascent and the third ascent of the peak of Cerro Negro Aspero (5500 meters, 18,045 feet). On September 29, 1991, a group of nine men and two women led by Luis Gómez ascended Cerro de la Fortuna (4376 meters, 14,358 feet) by a new route, the south side. From there, Campodónico alone traversed on to the summits of El Bronce Oeste and El Bronce (4000 and 4033 meters, 13,124 and 13,231 feet). On December 7, 1991, eight climbers from San Juan headed for the region near the Agua Negra international pass. That same day, they continued up to the gap between the twin peaks of Agua Negra and up the southeast ridge of Cerro El Arenal or Agua Negra II (5000 meters, 16,404 feet). Only Campodónico reached the summit; the hurried climb and the altitude affected all the others.
