Maipo, First Ski Ascent. The route for this, one of the very few ski ascents accomplished in the Andes, started at the military Refugio Cruz de Piedra, continued through Vegas del Yaucha, los Paramillos and on to a second hut called El Cilindro, built near the big lake of Diamante for scientific purposes. The two participants of this expedition, Daniel Alto and Rodolfo Grispo (Club Andinista Mendoza), reached the summit of Volcan Maipo (5290 meters, 17,356 feet) at seven P.M. on September 27. Due to the late hour, they had to bivouac at the base of the mountain.
