Nevado Tres Cruces is a high Andean massif straddling the Atacama Region of Chile and the Catamarca Province of Argentina, forming part of the Cordillera Occidental in the Andes Mountains. The massif comprises multiple summits, notable for high elevation, volcanic structures, and proximity to prominent features such as the Atacama Desert, Laguna Verde, and Ojos del Salado. It lies within a landscape shaped by regional tectonics involving the Nazca Plate, South American Plate, and ancient orogenic belts like the Andean orogeny.
The massif sits near the interprovincial boundary between Atacama Region authorities and Catamarca Province jurisdictions, north of the Salar de Maricunga and west of the Puna de Atacama. Surrounding landmarks include the Paso de San Francisco, the Maricunga Gold Belt, and hydrological features like the Rio Salado. Nearby human settlements and logistical hubs include Copiapó, Antofagasta, Fiambalá, and San Salvador de Jujuy, with transit routes such as the Ruta Nacional 60/Ruta CH-31. The massif lies within broader geographical contexts encompassing the Altiplano, the Bolivian Plateau, and physiographic provinces recognized by the Instituto Geográfico Nacional (Argentina) and the Instituto Geográfico Militar (Chile).
The massif is part of the Central Andean volcanic zone influenced by subduction of the Nazca Plate beneath the South American Plate, producing magmatism documented alongside volcanoes like Ojos del Salado, Llullaillaco, Licancabur, Lascar, and Cerro Galán. Rock suites include andesites, dacites, and rhyolites analogous to sequences at Cerro del Medio and the Puna volcanic province. Structural controls involve the Atacama Fault Zone and regional thrusts tied to the Andean orogeny. Petrological studies reference minerals also found at Copahue and Llaima, and geochronology ties eruptive phases to the Miocene and Pliocene epochs. Geothermal gradient and hydrothermal alteration link to deposits akin to the Maricunga Gold Belt and systems investigated by the Servicio Nacional de Geología y Minería (SERNAGEOMIN) and the Servicio Geológico Minero Argentino (SEGEMAR).
The massif comprises distinct summits including a main central peak and subsidiary summits characterized by steep ridges and volcanic domes similar to those on Ojos del Salado and Llullaillaco. Summit features include fumarolic fields, pumice cones, and erosional cirques comparable to those on Cerro San Francisco and Cerro Falso Azufre. Topographic prominence and ridge connections resemble configurations seen at Sierra Nevada formations and Cordillera de la Ramada. Altitude records are cross-referenced with cartographic data from the Instituto Geográfico Militar (Chile) and expedition logs from teams associated with institutions like the British Mountaineering Council and national alpine clubs such as the Club Andino de Chile and the Club Andino Bariloche.
High-elevation climate is cold and hyperarid due to proximity to the Atacama Desert and rain shadow from the Andes Mountains, with strong solar radiation and diurnal temperature ranges comparable to conditions on Aconcagua and Huascarán. Precipitation primarily arrives via austral summer South American Monsoon System pulses and westerly disturbances from the Pacific Ocean influenced by the Humboldt Current. Glaciation is limited; relic ice bodies and periglacial features mirror those studied on Nevado Ojos del Salado and Llullaillaco, with glacier recession trends monitored by researchers at the Universidad de Chile, Universidad Nacional de Salta, and international programs such as the Global Land Ice Measurements from Space (GLIMS) project.
Human interaction includes indigenous presence from groups like the Diaguita and Atacameño (Likan Antai) peoples, colonial-era transit along Paso de San Francisco, and scientific and mountaineering expeditions by teams from institutions including the Servicio Meteorológico Nacional (Argentina), US Geological Survey, Comisión Nacional de Energía Atómica (CNEA), and universities such as the Universidad de Buenos Aires and Pontificia Universidad Católica de Chile. Notable ascent history parallels pioneering climbs on Aconcagua, Ojos del Salado, and Llullaillaco executed by climbers associated with organisations like the American Alpine Club, Alpine Club (UK), and national alpine clubs. Expedition logistics have involved staging points in Copiapó, Fiambalá, and research outposts supported by agencies such as the Consejo Nacional de Investigaciones Científicas y Técnicas.
Biotic communities reflect puna and high Andean biomes with specialist flora and fauna comparable to those on the Altiplano and habitats such as Salar de Huasco and Salar de Uyuni. Vegetation includes cushion plants and xerophytic species studied by botanists at the Missouri Botanical Garden, Royal Botanic Gardens, Kew, and regional herbaria at the Museo de La Plata. Fauna includes highland camelids like Vicuña and Guanaco, avifauna such as the Andean condor, James's flamingo, and Cinnamon teal, and invertebrates akin to taxa catalogued by the Smithsonian Institution and the Museo Nacional de Ciencias Naturales (Madrid). Conservation and ecological research involve institutions like the Comisión Nacional de Áreas Naturales Protegidas (Argentina), Corporación Nacional Forestal (CONAF), and NGOs including WWF and Conservation International.
Land use intersects mining interests in the Maricunga Gold Belt, scientific research by institutions such as the Observatorio ALMA collaboration partners, and eco-tourism promoted by regional tourism boards like the Servicio Nacional de Turismo (SERNATUR). Protected area designations and management connect to frameworks used by the Comisión Nacional de Áreas Naturales Protegidas (Argentina), CONAF, and international instruments such as the Convention on Biological Diversity and the Ramsar Convention for nearby wetlands. Stakeholders include local municipalities like Copiapó Municipality and provincial authorities in Catamarca Province, as well as academic researchers from the Universidad de Antofagasta and Universidad Nacional de La Plata.
