Cerro Amarillo de Zenta, Ancient and Modern Ascents. Cerro Amarillo, of the Zenta range in the southeast of the Andes of Jujuy province, rises above forested hills and reaches a height of 3660 meters (12,008 feet). On July 30, our small party of the Club Andino Mercedario, made up of Teresa Bracco, Alberto Graffigna and me, reached the small hamlet of Alto Calilegua, within the boundaries of the Parque Nacional Calilegua. The peak was ascended by us in bad weather and a heavy snow fall forced us to cut short our stay on the summit, but we were able to examine the antigal (ancient ruins) built there by the Incas about half a millenium ago. The ruins are about 78 × 12 feet and reach in some constructions a height of 8 feet. Some staircases, very well built, can be used to ascend the lower parts of the mountain. Local farmers also climb the peak in modem times for semi-pagan ritual purposes. An antigal in the Zenta range had been vaguely reported 55 years ago by the great Argentinian archaeologist Eduardo Casanova and it was our fortune to verify its existence.
