Vinson Massif. During the southern 1990-1 winter, Pedro Nicolás and I made the first Spanish expedition to the Antarctic mountains to carry out geological research. We approached Vinson in the company of the Canadian Adventure Network, but we climbed separately and were in the region double the time they were. We followed the classic route, placing Base Camp, Camps I, II and III at 2400, 2600, 3200 and 3800 meters on November 26, 27, 30 and December 1. We got to the summit on December 2 at seven P.M. with a temperature of -35° C and a 35-kilometer-per-hour wind.
