Northern and Central Andes Corrections. Several errors were printed in AAJ, 1993 on pages 177 to 179. Ansilta 2 was climbed on March 28, 1991, not on the 25th. Ansilta 1 is also called Mazuelo. One of the climbers of Tridente was Alejandra Quenan (female), not Alejandro. They camped in the Quebrada de la Piedra Negra. Cerro Negro Aspero was climbed on August 18, 1991, not on the 8th. In the Agua Negra region, the 5000-meter peak we climbed and called Cerro del Paso de Agua Negra is just north of the Paso de Agua Negra. It is definitely not Cerro San Andrés, which is south of the pass and was ascended in 1904. In the report on new altitudes, Cajamarca should be Catamarca. In the central Andes, only Campodónica and Manzi climbed San Juan.
