Pata de Indio and Cerro Agua Negra, Central Andes. The newly opened international pass of Agua Negra, connecting San Juan, Argentina with La Serena, Chile, has made for easier access to the mountains. Alfredo Ceballos and I walked from the hamlet of Las Flores to the base of remote Pata de Indio. On October 7, Ceballos climbed it by a variant of the normal route while I ascended the steep ice gully of the south face. We met near the summit (5205 meters, 17,076 feet) and had a cold bivouac on the descent. On December 5, Fabio Pascual and I made another new route, that of the rocky north-northeast ridge of Agua Negra (5484 meters, 17,991 feet).
