Ascents in the Tres Gemelos Massif, Mendoza. This massif, as well

A scents in the Tres G emelos Massif, M endoza. This massif, as well as many others, was visit­ ed by Fitz Gerald and the Countess N adine Von M eyendorff in 1903. On January 8, 1995, Andres Amione and Glauco Muratti ascended Cerro Tres Gem elos (5241 m), the highest sum mit o f the massif, on the border with Chile. M ost o f the ascent was 30 degrees; the ice couloir, which is only eight to 10 meters wide, is 35-40 degrees, and the exit is 55-60 degrees. The sum mit is formed by rotten rock. The Aguja Ana (A na’s Needle, 4850 m) is close to G em elo Este and is the highest o f five nee­ dles. It can be seen from Laguna Horcones. It was ascended in October, 1996, by Muratti (3040 degree ice couloirs, and a chim ney o f good snow at 60 degrees). Undoubtedly the best ascent was Pico Bonito (4987 m). It was attempted in 1986 by Arranz and Gomez, but their attem pt was abandoned 250 meters beneath the summit. In 1989 Bianchi and Muratti tried another route but failed 100 meters before the top. On O ctober 13, 1994, Gabriel Piotto, Adrian Petrocelli, Diego Cancelo, Gervasio Fierro, Guillerm o Bianchi and G lauco Muratti finished the 1986 route. It had 45-degree unstable snow, and was a little steeper in the exit. This peak may have been first ascended by Von M eyendorff and party. M
