South America, Argentina, Peaks in the San Juan Region, Central Andes

New Altitudes in the Pissis-Bonete-Ojos del Salado Region. New altitudes have been published by the Instituto Geográfico Militar Argentino now that the Argentine-Chilean border controversy has been settled. The new map (Carta Topográfica Fiambalá Hoja 2769-IV y III, Provincias de Catamarca y La Rioja, 1:250,000) shows the new border. There are errors in the names of some mountains, which I note below. P 5891 (Cerro Peñas Azules) (5891m) (The Caldera del Inca is here called Laguna Caldera del Inca Pillo); Cerro Cenizo (5227m); Cerro Reclus (6335m); the badly named Cerro Bonete Grande (5943m); Cerro Nacimiento del Jagüé (5824m); Monte Pissis (6882m); Cerro Vidal Gormaz (5470m); Cerro Negro de la Laguna Verde (5764m); Cerro de la Coipa (5134m); Cerro del Matambre (5467m); Cerro Dos Hermanos, north summit (5530m); Cerro Aguas Calientes (5517m) (erroneously called here Morro Rasguido); Cerro Nacimiento (6436m) (erroneously called Cerro Bayo, which really lies to the south); Cerro de los Patos or Tres Quebradas (6239m); Cerro Ojos de las Lozas (5305m); Volcán Rojo (4861m); Volcán Negro (5373m); Cerro Incahuasi (6638m); Cerro El Fraile (6068m); P 5922 (Cerro Gendarme Argentino) (5922m); Cerro El Muerto (6488m); Cerro Walther Penck (6658m) (erroneously called Cerro Nacimiento, which is really south of this peak); Cerro Solo (6205m); Cerro Tres Cruces (6749m); Cerro Puntiagudo y Lamas (5980m). All of these errors in the names of mountains do not appear in the old 1:500,000 map of the region, also produced by the Instituto Geográfico Militar Argentino nor in the map of Claudio Bravo of the Club Andino Tucumán.
