Climbs in the Paine Group. The Asociación Universitaria de Andin- ismo, Santiago, organized a nine-man group to tackle Cerro “Fortaleza” (or “Fortress,” unofficial name), in the Paine group. In 20 days of attempts C. Gálvez and G. Oyarzún had only four of good weather. In several attempts they got to within 100 feet of the summit. Gálvez, with G. Casassa and J. Lanas made the second ascent of Cerro Trono Blanco (2500 meters, 8366 feet), which had been ascended by Chileans and Czechs in 1969 (A.A.J., 1970, p. 176). Other expedition members, C. Cognian, J. Piombo and G. Salamanca, plus Casassa, made the first ascent of the rock peak Aleta de Tiburón (“Shark’s Fin,” 1800 meters, 5905 feet). This expedition took place between January 2 and February 10.
