Ascents

The mountain is notoriously difficult and has seen very few successful ascents. The first ascent in July 1957 by the Austrian mountaineers and Siegfried Jungmair over the (north)east face has been called "one of the boldest climbing feats ever performed in the Cordillera".Jeremy Frimer

In 1964 Gary Colliver and Glen Denny of an American expedition climbed the north ridge to the slightly lower north summit, but a traverse over the "cockscomb of ice" connecting to the main summit has so far not been attempted.

forged the first route through the West face. On July 31, 1971 the Americans Dean Caldwell and Jon Bowlin first climbed the southwest face in two days. Leaving their expedition below, Bowlin and Caldwell forged their own route and reached the peak on August 1, and were back at base camp by August 2. In 1973, a Japanese team led by Masayuki Shinohara succeeded in climbing the south east face for the first time, though it took them 49 days.

Climbing

It is one of the hardest 6000 meter mountains of the Andes. The easier route to the summit is quoted TD but more difficult routes exist, many on them on vertical ice and with overhanging section of mixed terrain such as the Cassin route (70° ice and a pitch rated UIAA IV+).
