Erika and Yanina, first ascents; Gemelos Este, possible new route. Gemelos (The Twins) is a mountain near Las Cuevas and the Aconcagua area, near the Chilean border in Argentina’s Provincia de Mendoza. A group directed by Glauco Muratti was active here in October 2002. There was much snow, and the approach was a long one from Quebrada de Vargas, passing the Portezuelo Serrata to the base of Gemelos. The group ascended two twin rock towers of ca 4,750-4,800m, both virgin, christening them Erika and Yanina. The steepness was 50°. They also summited Gemelos Este (5,180m) by a possible new route, the Glaciar del Vasco (Basque Glacier).
