Cerro Domingo Faustino Sarmiento (Ansilta 7). Though this peak was first climbed in 1958 by the northwest ridge, it has rarely been visited. It is second in height in the Ansilta group, but the most difficult. Humberto Campodónico made the first ascent of the north ridge solo. On March 30, a truck of the border police left him at the Estancia los Arroyos and by afternoon he was camped at the Casa de Piedra. The next day, he reached Laguna Fría. On April 1, he camped on the edge of the Glaciar la Fría at the foot of a great ice wall. On the 2nd, he threaded through penitentes and moraines to camp at 4550 meters. On April 3, he climbed scree to the ridge, traversed the north summit to the highest peak (5780 meters, 18,963 feet). He descended from his camp by a different way to Villa Pituil, which he reached on April 6.
