East of Illampu and Ancohuma. The eastern cirques formed by Illampu and Ancohuma, two great 6000-meter peaks, and the vast ridge that connects them was so remote that it seemed best to share the benefits of group travel and a common Base Camp. Climbing, from easy snow climbs to granite walls at 6000 meters, attracted thirteen climbers. We traveled by bus from La Paz to Sorata. Then a remarkable old truck hauled us over the 15,700-foot Tipuani Pass to Ancoma. From there llamas and horses carried the bulk of our gear while we hiked past Cooco. At one point we saw 17 male condors circling. Base Camp at 14,800 feet was centrally situated for reaching the spectacular peaks. We enjoyed two weeks of almost perfect weather. The following is a summary of our activities. The climbs are given counter-clockwise on the map, starting at Base Camp.
