The Andes (/ˈændiːz/ AN-deez), Andes Mountains or Andean Mountain Range (Spanish: Cordillera de los Andes; Quechua: Anti) 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 (5,500 mi) long and 200 to 700 km (120 to 430 mi) wide (widest between 18°S and 20°S latitude) and has an average height of about 4,000 m (13,000 ft). The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela.
Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Arequipa, Bogotá, Cali, Medellín, El Alto, La Paz, Mérida, Santiago and Sucre. The Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes.
The Andes are the highest mountain range outside of Asia. The range's highest peak, Argentina's Aconcagua, rises to an elevation of about 6,961 m (22,838 ft) above sea level. The peak of Chimborazo in the Ecuadorian Andes is farther from the Earth's center than any other location on the Earth's surface, due to the equatorial bulge resulting from the Earth's rotation. The world's highest volcanoes are in the Andes, including Ojos del Salado on the Chile–Argentina border, which rises to 6,893 m (22,615 ft). (Full article...)

Purace volcano seen from Popayán in 2006
Puracé is an andesitic stratovolcano located in the Puracé National Natural Park in the Cauca Department, Colombia. It is part of the North Volcanic Zone of the Andean Volcanic Belt. The volcano is located at the intersection of the Coconucos and Morras Faults.
It is one of the most active volcanoes in Colombia. Large explosive eruptions occurred in 1849, 1869, 1885, 1949, 1950, 1956, and 1957. There were about a dozen eruptions in the 20th century, the most recent being in 1977, until 19 January 2025 when Puracé once again erupted. On this occasion, volcanic ash was deposited 7 kilometres (4.3 mi) away. Fumaroles were seen near the summit in 1990, and hot springs emerged from some of the lower slopes. Th (Full article...) -

Mount Darwin (Spanish: Monte Darwin) is a peak in Isla Grande de Tierra del Fuego forming part of the Cordillera Darwin, the southernmost range of the Andes, just to the north of the Beagle Channel. It is 2,438 m (7,999 ft) high.
Monte Darwin was for a long time considered as the highest peak in Tierra del Fuego, but that distinction corresponds to a nearby mountain unofficially named Monte Shipton (also somewhat confusingly referred to as Darwin or Agostini-Darwin), which is about 2,580 m (8,460 ft) high and is located at . Both peaks are best climbed in late December, January, February and March. Monte Shipton was first climbed in 1962 by Eric Shipton, E. Garcia, F. Vivanco and C. Marangunic. (Full article...) -

The Andean Volcanic Belt is a major volcanic belt along the Andean cordillera in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. It is formed as a result of subduction of the Nazca plate and Antarctic plate underneath the South American plate. The belt is subdivided into four main volcanic zones which are separated by volcanic gaps. The volcanoes of the belt are diverse in terms of activity style, products, and morphology. While some differences can be explained by which volcanic zone a volcano belongs to, there are significant differences within volcanic zones and even between neighboring volcanoes. Despite being a type location for calc-alkalic and subduction volcanism, the Andean Volcanic Belt has a broad range of volcano-tectonic settings, as it has rift systems and extensional zones, transpressional faults, subduction of mid-ocean ridges and seamount chains as well as a large range of crustal thicknesses and magma ascent paths and different amounts of crustal assimilations.
Romeral in Colombia is the northernmost active member of the Andean Volcanic Belt. South of latitude 49° S within the Austral Volcanic Zone volcanic activity decreases with the southernmost volcano Fueguino in Tierra del Fuego archipelago. (Full article...) -

Illimani’s southwestern slopes viewed from La Paz in December 2001
Illimani (Aymara and Spanish pronunciation: [iʎiˈmani]) is a prominent fold mountain within the Cordillera Real of Bolivia, a subrange of the greater Andes, and located approximately 82 kilometres (51 mi) southeast of La Paz. With an elevation of 6,438 metres (21,120 ft) at its summit, it is the highest mountain in the Cordillera Real and the second-highest in Bolivia, surpassed by Nevado Sajama.
The mountain lies in the transitional zone between the high Altiplano plateau to the west and the deep valleys of the Yungas region to the east. Its snow-capped massif consists of four major peaks arranged on a north–south axis. Its composition is of made of metamorphic rock and intrusive granites. Its formation results from the ancient folding associated with the Andean orogeny, as with the majority of the neighboring mountains in the cordillera. The snow line lies at about 4,570 metres (15,000 ft) above sea level, and glaciers are found on the northern face at 4,982 metres (16,350 ft). (Full article...) -

Imbabura, with corn fields in the foreground.
Imbabura is an inactive stratovolcano in northern Ecuador. Although it has not erupted for about 7,500 years, it is not thought to be extinct. Imbabura is intermittently capped with snow and has no permanent glaciers.
Covered in volcanic ash, the slopes of Imbabura are especially fertile. In addition to cloud forests, which are found across the northern Andes to an altitude of 3000 m, the land around Imbabura is extensively farmed. Maize, sugarcane, and beans are all staple crops of the region. Cattle are also an important commodity, and much of the land on and around Imbabura, especially the high-altitude meadows above the tree line, is used for grazing. (Full article...) -

Chinchilla lanigera at the Wrocław Zoo in Poland
Chinchilla is a genus consisting of two species (Chinchilla chinchilla and Chinchilla lanigera) of crepuscular rodents of the parvorder Caviomorpha, native to the Andes Mountains in South America. They live in colonies called "herds" at high elevations up to 4,270 m (14,000 ft). Historically, chinchillas lived in an area that included parts of Bolivia, Peru and Chile, but today, colonies in the wild are known only in Chile. Along with their relatives, viscachas, they make up the family Chinchillidae. They are also related to the chinchilla rat.
Chinchillas have the densest fur of all extant terrestrial mammals, with around 20,000 hairs per square centimeter and 50 hairs growing from each follicle. The chinchilla is named after the Chincha people of the Andes, who once wore its dense, velvet-like fur and ate their meat. By the end of the 19th century, chinchillas had become quite rare after being hunted for their notably soft fur. Most chinchillas currently used by the fur industry for clothing and other accessories are farm-raised. Domestic chinchillas descended from C. lanigera are sometimes kept as pets, and may be considered a type of pocket pet. (Full article...) -

Tata Sabaya is a 5,430-metre (17,810 ft) high volcano in Bolivia. It is part of the Central Volcanic Zone, one of several volcanic belts in the Andes which are separated by gaps without volcanic activity. This section of the Andes was volcanically active since the Jurassic, with an episode of strong ignimbritic volcanism occurring during the Miocene. Tata Sabaya lies in a thinly populated region north of the Salar de Coipasa salt pan.
Volcanic activity at Tata Sabaya and elsewhere in the Central Volcanic Zone is the consequence of the subduction of the Nazca Plate beneath the South America Plate. The volcano has developed along a lineament that separates older crust north of the lineament from younger crust in the south, and the edifice has been formed by andesitic rocks. (Full article...) -

Torres del Paine
The Cordillera Paine is a group of mountains (a cordillera) in Torres del Paine National Park in Chilean Patagonia. It is 280 km (170 mi) north of Punta Arenas, and about 1,960 km (1,220 mi) south of the Chilean capital Santiago. The cordillera is part of the Commune of Torres del Paine in Última Esperanza Province of Magallanes and Antártica Chilena Region. No accurate surveys have been published, and published elevations have been claimed to be seriously inflated, so most of the elevations given on this page are approximate. Paine means "blue" in the native Tehuelche (Aonikenk) language and is pronounced PIE-nay. (Full article...) -

Cone of Reventador in 2012 (V. Scherrer)
Reventador is an active stratovolcano which lies in the eastern Andes of Ecuador. It lies in a remote area of the national park of the same name, which is Spanish for "exploder". Since 1541, it has erupted over 25 times, although its isolated location means that many of its eruptions have gone unreported.
The largest historical eruption occurred in 2002. During that eruption, the plume from the volcano reached a height of 17 kilometres (11 mi) and pyroclastic flows proceeded to 7 kilometres (4.3 mi) from the cone. On March 30, 2007, the mountain ejected ash to a height of about 3.2 kilometres (2.0 mi). No injuries or damage were reported. Its most recent eruption began on 27 July 2008, and it has remained in continuing eruption status (intermittent eruptive events without a break of 3 months or more) as of 15 October 2021.

Orestias cuvieri
Orestias is a genus of pupfish. Older systematics classified them into the own family Orestiidae. They are found in lakes, rivers and springs in the Andean highlands of South America, and several species are considered threatened. They are egg-laying fish that feed on small animals and plant matter. The largest species can reach a total length of 27 cm (10.6 in), but most remain far smaller. Their most characteristic feature is the absence of the ventral fin, although this is shared by a few other pupfish. Despite their moderate to small size, they are important to local fisheries and a few species are farmed.
Several species are locally and colloquially known as carache. The name of the genus is a reference to Orestes, a Greek mythological character who Valenciennes described as the "nymph of the mountains". (Full article...) -

Male R. p. sanguinolentus, Colombia
The Andean cock-of-the-rock (Rupicola peruvianus), also known as tunki (Quechua), is a large passerine bird of the cotinga family native to Andean cloud forests in South America. It is the national bird of Peru. It has four subspecies and its closest relative is the Guianan cock-of-the-rock.
The Andean cock-of-the-rock exhibits marked sexual dimorphism; the male has a large disk-like crest and scarlet or brilliant orange plumage, while the female is significantly darker and browner. Gatherings of males compete for breeding females with each male displaying his colourful plumage, bobbing and hopping, and making a variety of calls. After mating, the female makes a nest under a rocky overhang, incubates the eggs, and rears the young by herself. (Full article...) -

Incahuasi volcano as seen from route 60, Fiambala, Argentina
Incahuasi (Spanish pronunciation: [iŋkaˈwasi]; possibly from Quechua: inka Inca, wasi house) is a volcanic mountain in the Andes of South America. It lies on the border of the Catamarca Province of Argentina and the Atacama Region of Chile. Incahuasi has a summit elevation of 6,621 metres (21,722 ft) above sea level.
The volcano consists of a 3.5-kilometre-wide (2.2 mi) caldera and two stratovolcanoes. Four pyroclastic cones located 7 kilometres (4.3 mi) to the northeast have produced basalt-andesite lava flows that cover an area of 10 square kilometres (4 sq mi). (Full article...) -

The double peak of The Illinizas
The Illinizas are a pair of volcanic mountains that are located in the north of Latacunga, Cotopaxi, Ecuador. They are located in the Illinizas Ecological Reserve (Spanish: Reserva Ecológica Los Illinizas). These twin mountains are separated by a saddle that is about a kilometer long. The peaks are among the highest in Ecuador, with Illiniza Sur standing slightly taller than Illiniza Norte, its northern counterpart, at 5248 metres and 5126 metres respectively.
Most guidebooks (for example, Lonely Planet Ecuador, Ecuador: A Climbing Guide) spell the mountain with only one "l" as in Iliniza. The name Illinizas is derived from the Kunza words for "masculine hill." (Full article...) -

Cumbal in 2011
Cumbal is a stratovolcano of the Caribe Terrane, located at the Nudo de los Pastos in Nariño, Colombia. It is the southernmost historically active volcano of Colombia and is together with Chiles and Azufral one of the few volcanoes of the Western Ranges. The volcano is dominated by andesites.
On July 10, 2012, the Colombian Geological Service changed the activity level of the volcano from green to yellow, motivated by changes in the behavior of the volcanic edifice, a situation that still persists. (Full article...) -

Location of Cerro Maca
Cerro Macá is a stratovolcano located to the north of the Aisén Fjord and to the east of the Moraleda Channel, in the Aysén del General Carlos Ibáñez del Campo Region of Chile. This glacier-covered volcano lies along the regional Liquiñe-Ofqui Fault Zone.
Cerro Macá is a relatively small volcano with a volume of only 39 cubic kilometres (9.4 cu mi). It has a summit elevation of approximately 2,300 m above sea level and features glaciers that in 2011 covered an area of 27.62 square kilometres (10.66 sq mi). The edifice is partially eroded and a sector collapse is probably the origin of a large steep sided depression in the summit area. Pyroclastic cones with associated lava flows are found on its southwestern flank but also on the other slopes of the volcano, as far down as sea level and in the Bahia Aysen. (Full article...) -

Falso Azufre volcanic complex and Laguna Verde.
Falso Azufre is a complex volcano at the border of Argentina and Chile.
Falso Azufre is elongated in east–west direction and contains craters and lava domes; most craters have diameters of 300–600 metres (980–1,970 ft) with the exception of the main crater, which is 1 by 1.3 kilometres (0.62 mi × 0.81 mi) wide. The highest summit Cerro Falso Azufre lies at the western end in Chile, which has mostly generated pyroclastic material from craters. The probably youngest segment of the volcano is the eastern section in Argentina, where two lava domes and two cones are located; these form the Dos Conos volcano. Some lava flows linked to Dos Conos are up to 7 kilometres (4.3 mi) long. The oldest is known as the Kunstmann edifice on the northwestern side of Falso Azufre; Kunstmann volcano features a 3 kilometres (1.9 mi) wide scar formed by a sector collapse. Falso Azufre with a base surface of 387 square kilometres (149 sq mi) is one of the biggest volcanoes in the area. The presence of two oppositely curved vent alignments gives the complex an arc-like shape which reaches heights of about 5,900 metres (19,400 ft) above sea level. (Full article...) -

The llama (/ˈlɑːmə/; Spanish pronunciation: [ˈʎama] or [ˈʝama]) (Lama glama) is a domesticated South American camelid, widely used as a meat and pack animal by Andean cultures since the pre-Columbian era.
Llamas are social animals and live with others as a herd. Their wool is soft and contains only a small amount of lanolin. Llamas can learn simple tasks after a few repetitions. When using a pack, they can carry about 25 to 30% of their body weight for 8 to 13 km (5–8 miles). The name llama (also historically spelled "lama" or "glama") was adopted by European settlers from native Peruvians. (Full article...)
