The Andes, Andes Mountains or Andean Mountain Range are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 km (5,530 mi) long and 200 to 700 km wide and has an average height of about 4,000 m (13,123 ft). The Andes extend from South to North through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela.
The Altiplano, Collao or Andean Plateau, in west-central South America, is the most extensive high plateau on Earth outside Tibet. The plateau is located at the latitude of the widest part of the north–south-trending Andes. The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, and its southwestern fringes lie in Chile.
Aspidosperma quebracho-blanco, commonly known as Quebracho blanco, kebrako, or white quebracho, is a South American tree species, native to Brazil, northern Argentina, Bolivia, Paraguay, and Uruguay. It must not be confused with other species also known as quebracho, but belonging to the genus Schinopsis.
When the Spanish arrived, they divided Peru into three main regions: the coastal region, that is bounded by the Pacific Ocean; the highlands, that is located on the Andean Heights, and the jungle, that is located on the Amazonian Jungle. But Javier Pulgar Vidal, a geographer who studied the biogeographic reality of the Peruvian territory for a long time, proposed the creation of eight Natural Regions. In 1941, he presented his thesis "Las Ocho Regiones Naturales del Perú" at the III General Assembly of the Pan-American Institute of Geography and History.
Lauca National Park is in Chile's far north, in the Andean range. It encompasses an area of 1,379 km2 of altiplano and mountains, the latter consisting mainly of enormous volcanoes. Las Vicuñas National Reserve is its neighbour to the south. Both protected areas, along with Salar de Surire Natural Monument, form Lauca Biosphere Reserve. The park borders Sajama National Park in Bolivia.
The puna grassland ecoregion, of the montane grasslands and shrublands biome, is found in the central Andes Mountains of South America. It is considered one of the eight Natural Regions in Peru, but extends south, across Chile, Bolivia, and western northwest Argentina. The term puna encompasses diverse ecosystems of the high Central Andes above 3200–3400 m.
Los Flamencos National Reserve is a nature reserve located in the commune of San Pedro de Atacama, Antofagasta Region of northern Chile. The reserve covers a total area of 740 square kilometres (290 sq mi) in the Central Andean dry puna ecoregion and consists of seven separate sections.
The taruca, also known as the Peruvian guemal, north Andean deer, north Andean huemul, northern huemul or northern guemal, is a mid sized deer species that inhabits the high regions of the Andes mountains in South America. The common name taruca means "deer" in both the Quechua and Aymara languages, though these are not interrelated. The taruca is closely related to the southern guemal, the only other member of the Hippocamelus genus.
The Andean hillstar is a species of hummingbird in the "coquettes", tribe Lesbiini of subfamily Lesbiinae. It is found in Argentina, Bolivia, Chile, and Peru.
The Andean flicker is a species of bird in subfamily Picinae of the woodpecker family Picidae. It is found in Argentina, Bolivia, Chile, Ecuador, and Peru.
The Central Andean dry puna (NT1001) is an ecoregion in the montane grasslands and shrublands biome, located in the Andean Altiplano in South America. It is a part of the Puna grassland.
The Eduardo Avaroa Andean Fauna National Reserve is located in Sur Lípez Province. Situated in the far southwestern region of Bolivia, it is the country's most visited protected area. It is considered the most important protected area in terms of tourist influx in the Potosí Department.
San Guillermo National Park is a national park in Argentina, in the Iglesia Department of San Juan Province. It was established in 1998 and is part of the San Guillermo Biosphere Reserve. Elevations in the biosphere range from 2,100 metres (6,900 ft) to 6,380 metres (20,930 ft). Vegetation in the National Park and biosphere consists of barren desert, grasslands, and a few wetlands, all located in the high, arid Andes. The animals include vicuña, guanaco, culpeo fox, Andean mountain cat, cougar, and Andean condor.
The Southern Andean steppe is a montane grasslands and shrublands ecoregion occurring along the border of Chile and Argentina in the high elevations of the southern Andes mountain range.
The Central Andean puna is a montane grasslands and shrublands ecoregion in the Andes of southern Peru, Bolivia, and northern Chile and Argentina.
The vertical archipelago is a term coined by sociologist and anthropologist John Victor Murra under the influence of economist Karl Polanyi to describe the native Andean agricultural economic model of accessing and distributing resources. While some cultures developed market economies, the predominant models were systems of barter and shared labor. These reached their greatest development under the Inca Empire. Scholars have identified four distinct ecozones, at different elevations.
Asana River is a waterway in the Moquegua Region of southern Peru. It is one of the tributaries of the Osmore River. The Asana archaeological site, occupied over the course of 8,000 years, is situated in a basin on the river's north bank. The Quellaveco mining project sought to divert the Asana for extractive waste material placement in its copper mining operations.
Tocomar is a Pleistocene volcano in the Jujuy Province, Argentina. It is part of the Andean Volcanic Belt, more specifically to its sub-belt the Central Volcanic Zone. The Central Volcanic Zone consists of about 44 active volcanoes and large calderas of the Altiplano-Puna volcanic complex. Volcanism there is caused by the subduction of the Nazca Plate beneath the South America Plate in the Peru-Chile Trench. At Tocomar, volcanism is further influenced by a large fault zone, the Calama-Olacapato-El Toro fault, which runs diagonally across the volcanic arc.
Ojos de Mar is a group of 3–6 small water bodies close to the town of Tolar Grande in Argentina and an important tourist attraction there. They are inhabited by extremophile microorganisms of interest to biotechnology; stromatolites have also been found there.
Cerro Tuzgle is a dormant stratovolcano in the Susques Department of Jujuy Province in northwestern Argentina. Tuzgle is a prominent volcano of the back arc of the Andes and lies about 280 kilometres (170 mi) east of the main volcanic arc. Part of the Central Volcanic Zone of the Andes, its summit is 5,486 metres (17,999 ft) above sea level and it grew during different stages over a caldera and lava domes. Some major lava flows emanate from the summit crater, and one confirmed and one possible flank collapse unit as well as an ignimbrite sheet are associated with Tuzgle.
