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 (5,530 mi) long and 200 to 700 km (124 to 435 mi) wide (widest between 18°S and 20°S latitude) 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.
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 Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto, and La Paz. 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 which is 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...)

Nevado de Santa Isabel (English: "The Snowy of Saint Isabel") is a shield volcano straddling the boundaries of the Colombian departments of Tolima, Caldas, and Risaralda, being the highest point of the latter. The volcano lies approximately 10 kilometers southwest of the larger Nevado del Ruiz volcano. Santa Isabel is the third highest peak in Los Nevados National Natural Park. It is a relatively flat volcano with three domes of nearly equal elevation. (Full article...) -
Coropuna is a dormant compound volcano located in the Andes mountains of southeast-central Peru. The upper reaches of Coropuna consist of several perennially snowbound conical summits, lending it the name Nevado Coropuna in Spanish. The complex extends over an area of 240 square kilometres (93 sq mi) and its highest summit reaches an altitude of 6,377 metres (20,922 ft) above sea level. This makes the Coropuna complex the third-highest of Peru. Its thick ice cap is the most extensive in Earth's tropical zone, with several outlet glaciers stretching out to lower altitudes. Below an elevation of 5,000 metres (16,000 ft), there are various vegetation belts which include trees, peat bogs, grasses and also agricultural areas and pastures.
The Coropuna complex consists of several stratovolcanoes. These are composed chiefly of ignimbrites and lava flows on a basement formed by Middle Miocene ignimbrites and lava flows. The Coropuna complex has been active for at least five million years, with the bulk of the current cone having been formed during the Quaternary. Coropuna has had two or three Holocene eruptions 2,100 ± 200 and either 1,100 ± 100 or 700 ± 200 years ago which generated lava flows, plus an additional eruption which may have taken place some 6,000 years ago. Current activity occurs exclusively in the form of hot springs. (Full article...) -
The Puracé National Natural Park (Spanish: Parque Nacional Natural Puracé) is a national park located in the Andean region of Colombia, southeast of the city of Popayán in the Cordillera Central range. Its main feature is the active stratovolcano Puracé, one of Colombia's most active volcanoes. Four of the country's most important rivers originate within the area: Magdalena River, Cauca River, Japurá River and Patía River. (Full article...) -
The Pico Piedras Blancas (also known as Misamán), at 4,737 metres (15,541 ft), is the highest mountain of the Sierra de la Culata range in the Mérida State, and the fifth-highest mountain in Venezuela. Its name, meaning "White Stones", is of uncertain origin, since the massif is predominantly grey in color. Pico Piedras Blancas lacks glaciers; however, seasonal snowfalls may briefly cover its flanks. From its summit and under clear conditions, Lake Maracaibo can be seen. One of the accesses to reach the base of the mountain, is through the Mifafí Condor Reserve, which hosts some specimens of this andean bird. (Full article...) -
Cordón del Azufre is an inactive complex volcano located in the Central Andes, at the border of Argentina and Chile. It consists of three stages of volcanic cones and associated lava flows, and its activity is a consequence of the subduction of the Nazca Plate underneath the South American Plate. North of it are the dormant volcano Lastarria and the actively uplifting Lazufre region. (Full article...) -
The Andean condor (Vultur gryphus) is a South American New World vulture and is the only member of the genus Vultur. It is found in the Andes mountains and adjacent Pacific coasts of western South America. With a maximum wingspan of 3.3 m (10 ft 10 in) and weight of 15 kg (33 lb), the Andean condor is one of the largest flying birds in the world, and is generally considered to be the largest bird of prey in the world.
It is a large black vulture with a ruff of white feathers surrounding the base of the neck and, especially in the male, large white patches on the wings. The head and neck are nearly featherless, and are a dull red color, which may flush and therefore change color in response to the bird's emotional state. In the male, there is a wattle on the neck and a large, dark red comb or caruncle on the crown of the head. The female condor is smaller than the male, an exception to the usual sexual dimorphism seen in birds of prey. (Full article...) -
Nahuel Huapi National Park (Spanish: Parque Nacional Nahuel Huapi) is the oldest national park in Argentina, established in 1922 as Parque Nacional de Sud and reconfiguered in 1934. It surrounds Nahuel Huapi Lake in the foothills of the Patagonian Andes. The largest of the national parks in the region, it has an area of 7,050 km2 (2,720 sq mi), or nearly 2 million acres. Its landscapes represent the north Patagonian Andean Zone consisting of three types, namely, the Altoandino (with perpetual snow above an altitude of 1,600 metres (5,200 ft)), the Andino-Patagónico (in the lower reaches of the hills) and the Patagonian steppe. It also represents small parts of the Valdivian Rainforest.
The park and the reserve lie at an altitude of 720–3,574 metres (2,362–11,726 ft), and are designated under IUCN management categories II (National Park) and IV (Management Reserve). The park is completely protected while the reserve is partially protected. The national park is dominated by the high mountain chain of the Andes, many lakes, rapid rivers, waterfalls, snow-clad peaks, glaciers and extensive forests. It is bordered by Chile on its western side. (Full article...) -
The Nevado del Quindío, also known as Volcán Paramillo del Quindío or simply Paramillo del Quindío, is an inactive volcano located in the Central Cordillera of the Andes in central Colombia. The summit marks the tripoint of the departments of Risaralda, Tolima, and Quindío, and is the highest point of the latter. The mountain is the fourth highest peak in Los Nevados National Natural Park among those with a topographic prominence exceeding 300 meters. There are no historical records of any eruption. The andesitic volcano is located on top of the Palestina Fault.
The mountain formerly had glaciers, which disappeared in the second half of the 20th century due to changing climatic conditions associated with global warming. Presently there is no permanent ice, only intermittent snow. The mountain's alternative designation as "paramillo" (like paramo, a high-elevation area of sparse vegetation exposed to wind, rain, and cold) reflects this new reality, whereas the term "nevado" inaccurately implies continuous snow cover.

Parinacota (in Hispanicized spelling), Parina Quta or Parinaquta is a dormant stratovolcano on the border of Bolivia and Chile. Together with Pomerape it forms the Nevados de Payachata volcanic chain. Part of the Central Volcanic Zone of the Andes, its summit reaches an elevation of 6,380 metres (20,930 ft) above sea level. The symmetrical cone is capped by a summit crater with widths of 1 kilometre (0.62 mi) or 1,000 metres (3,300 ft). Farther down on the southern slopes lie three parasitic centres known as the Ajata cones. These cones have generated lava flows. The volcano overlies a platform formed by lava domes and andesitic lava flows.
The volcano started growing during the Pleistocene and formed a large cone. At some point between the Pleistocene and the Holocene, the western flank of the volcano collapsed, generating a giant landslide that spread west and formed a large, hummocky landslide deposit. The avalanche crossed and dammed a previously existing drainage, impounding or enlarging Lake Chungará; numerous other lakes now forming the headwaters of the Rio Lauca sprang up within the deposit. Volcanic activity rebuilt the cone after the collapse, cancelling out the collapse scar. (Full article...) -
Artesonraju is a pyramidal mountain peak located near the city of Caraz in the Cordillera Blanca mountain range in the Peruvian Andes. It is located at the Peruvian province of Huaylas and its slopes are within two cities: Santa Cruz and Caraz. Its summit has an elevation of 6,025 metres (19,767 ft) (or 5,999 metres (19,682 ft) according to the IGN-Peru map). It is one of many prominent peaks (2772 metres) located within the boundaries of Peru's Huascarán National Park.
Artesonraju has two distinguished climbing routes. Due to their difficulties, Artesonraju is seldom successfully climbed in comparison to other well known mountains in the Cordillera Blanca. This mountain serves as the inspiration mascot for the newer Paramount Pictures production logo. (Full article...) -
Maipo is a stratovolcano in the Andes, lying on the border between Argentina and Chile. It is located 90 km (56 mi) south of Tupungato and about 100 km (62 mi) southeast of Santiago. It has a symmetrical, conical volcanic shape, and is among the southernmost 5,000 metre peaks in the Andes.
Maipo is located within the Diamante caldera, a feature measuring 15 km by 20 km that is about half a million years old. It rises about 1,900 m (6,230 ft) above the floor of the caldera. Immediately to the east of the peak, on the eastern side of the caldera floor, is Laguna del Diamante, a lake that formed when lava flows blocked drainage channels from the caldera in 1826. The Diamante Caldera erupted 450 cubic kilometers (108 cu mi) of tephra, 450 ka. (Full article...) -
Illimani (Aymara and Spanish pronunciation: [iʎiˈmani]) is the highest mountain in the Cordillera Real (part of the Cordillera Oriental, a subrange of the Andes) of western Bolivia. It lies near the cities of El Alto and La Paz at the eastern edge of the Altiplano. It is the second highest peak in Bolivia, after Nevado Sajama, and the eighteenth highest peak in South America. 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 m (16,350 ft). The mountain has four main peaks; the highest is the south summit, Nevado Illimani, which is a popular ascent for mountain climbers.
Geologically, Illimani is composed primarily of granodiorite, intruded during the Cenozoic era into the sedimentary rock, which forms the bulk of the Cordillera Real. (Full article...) -
Cerro Bayo is a complex volcano on the northern part border between Argentina and Chile. It consists of four overlapping stratovolcanoes along a north–south line. The main volcano face is located on the Argentine side, thought the summit of the complex is just west of the border, in Chile. The volcano is about 800,000 years old, but it is associated with ongoing ground uplift encompassing also the more northerly Lastarria and Cordón del Azufre volcanoes. The 5,401-metre (17,720 ft) high summit is the source of two viscous dacitic lava flows with prominent levees that traveled to the north.
Elemental sulfur can be found at Bayo, both in the form of high-grade massive deposits and as extinct fumarole chimneys. The volcano formed in three separate phases that produced lava flows. One is dated to 1.6±0.4 million years ago. The volcano can bear snow in winter. The youngest dated rocks are about 23,000 years old; in 2007 a steam eruption were observed by researchers investigating nearby salt pans such as Salar Ignorado. (Full article...) -
The Cordillera Paine is a mountain group in Torres del Paine National Park in Chilean Patagonia. The cordillera is located 280 km (170 mi) north of Punta Arenas, and about 1,960 km (1,220 mi) south of the Chilean capital Santiago. It belongs to 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...) -
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.

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...) -
Cerro Bonete is a mountain in the north of the province of La Rioja, Argentina, near the provincial border with Catamarca.
Its summit is 6,759 m above mean sea level, making it the fifth-highest separate mountain in the Americas (after Aconcagua, Ojos del Salado, Monte Pissis, and Huascaran). SRTM data disproves the frequently-made claim that its summit is 6,872 m above sea level. (Full article...) -
Telmatobius culeus, commonly known as the Titicaca water frog or Lake Titicaca frog, is a medium-large to very large and endangered species of frog in the family Telmatobiidae. It is entirely aquatic and found only in the Lake Titicaca basin, including rivers that flow into it and smaller connected lakes like Arapa, Lagunillas and Saracocha, in the Andean highlands of Bolivia and Peru. In reference to its excessive amounts of skin, it has jokingly been referred to as the Titicaca scrotum (water) frog.
It is closely related to the more widespread and semiaquatic marbled water frog (T. marmoratus), which also occurs in shallow, coastal parts of Lake Titicaca, but lacks the excessive skin and it is generally smaller (although overlapping in size with some forms of the Titicaca water frog).

Nevado del Huila (/nɛˈvɑːdoʊ dɛl ˈwiːlə/, Spanish pronunciation: [neˈβaðo ðel ˈwila]) at 5,364 metres (17,598 ft), is the highest volcano in Colombia, located at the tripoint of the departments of Huila, Tolima and Cauca. It is visible from the city of Cali. The andesitic volcano is located on top of the Ibagué Batholith.
After being dormant for more than 500 years, the volcano showed heavy signs of activity in 2007 and 2008. As of February 20, 2007, there were more than 7000 "minor" seismic events, and a high state of alert was in place for the departments of Cauca, Huila, Caldas and Valle del Cauca. The volcano erupted twice in April 2007, once in April 2008 and again in November 2008. Any eruption would affect the small villages around the volcano, mostly Páez, where their inhabitants still have in memory the eruption of the Nevado del Ruiz volcano and the destruction of Armero.

Chumpe (possibly from Quechua chumpi: belt), Jatunriti, Ñanaloma or Yanaloma is a mountain in the Vilcanota mountain range in the Andes of Peru with 6,106 metres (20,033 ft) of elevation. It is located in the Cusco Region, Canchis Province, Pitumarca District as well as in the Quispicanchi Province, Ocongate District. Chumpe lies north of Lake Sibinacocha. (Full article...) -
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...) -
Hudson Volcano (Spanish: Volcán Hudson, Cerro Hudson, or Monte Hudson) is the most active volcano in the southern part of the Southern Volcanic Zone of the Andes Mountains in Chile, having erupted most recently in 2011. It was formed by the subduction of the oceanic Nazca Plate under the continental South American Plate. South of Hudson is a smaller volcano, followed by a long gap without active volcanoes, then the Austral Volcanic Zone. Hudson has the form of a 10-kilometre-wide (6-mile) caldera filled with ice; the Huemules Glacier emerges from the northwestern side of the caldera. The volcano has erupted rocks ranging from basalt to rhyolite, but large parts of the caldera are formed by non-volcanic rocks.
The volcano erupted numerous times in the late Pleistocene and Holocene, forming widespread tephra deposits both in the proximity of Hudson and in the wider region.
Four large eruptions took place in 17,300–17,440 BP ("H0 eruption"), 7,750 BP ("H1 eruption"), 4,200 BP ("H2 eruption") and in 1991 AD ("H3 eruption"); the second is among the most intense volcanic eruptions in South America during the Holocene. A smaller eruption occurred in 1971. The 7,750 BP and 1991 eruptions had a substantial impact on the human population of Patagonia and (for the 7,750 BP eruption) Tierra del Fuego: The 7,750 BP eruption devastated the local ecosystem and may have caused substantial shifts in human settlement and lifestyle. During the 1991 eruption, volcanic ash covered a large area in Chile and neighbouring Argentina, causing high mortality in farm animals, aggravating an existing economic crisis, and reaching as far as Antarctica.

Pumasillo (possibly from Quechua puma cougar, puma, sillu claw, "puma claw") is a mountain in the Vilcabamba mountain range in the Andes of Peru, about 5,991 m (19,656 ft) high'. Pumasillo or Sacsarayoc also refers to the whole massif. It includes the peaks Pumasillo, Sacsarayoc and Lasunayoc. It is located in the Cusco Region, La Convención Province. Its slopes are within the administrative boundaries of the Peruvian city of Santa Teresa. ('Full article...) -
Janq'u Uma (Aymara janq'u white, uma water, "white water", also spelled Ccancouma, Janjouma) is a mountain in the north of the Apolobamba mountain range in the Andes of Peru, about 4,900 metres (16,076 ft) high. It is located in the Puno Region, Sandia Province, Cuyocuyo District. Janq'u Uma lies northwest of the mountain Wilaquta, northeast of Qurwari and southwest of Utkhuqaqa. Two little streams named Janq'u Uma (Janjouma) and Qullqipirwa (Jolljepirhua) originate west and east of the mountain. They flow to the river Lawa Lawani which runs to the north. It belongs to the watershed of the Inambari River. (Full article...)

The Sierra de La Culata is a mountain range in the largest massif in Venezuela, the Cordillera de Mérida, which in turn is part of the northern extent of the Cordillera de los Andes (Andes Mountains). The Sierra la Culata includes some of the highest peaks in Venezuela, such as Pico Piedras Blancas, Pico Pan de Azúcar, and Collado del Cóndor.
It is located between the states of Mérida and Trujillo. Most of the lagoons are a result of the Mérida glaciation. (Full article...)
