The Andes (/ˈændiːz/ AN-deez Ananta), 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 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 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...)

Huaytapallana (possibly from in the Quechua spelling Waytapallana; wayta wild flower, a little bunch of flowers, pallay to collect, pallana an instrument to collect fruit / collectable, Waytapallana "a place where you collect wild flowers",) or Lasuntay is the highest peak in the Huaytapallana mountain range in the Andes of Peru. Its summit reaches about 5,557 m (18,232 ft) above sea level. The mountain is situated in the Junín Region, Huancayo Province, in the districts of Huancayo and Pariahuanca. (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...) -
Cerro Castillo Dynevor, also known as Castillo Dynevor is located on the northwest coast of Skyring Sound, in Magallanes Region, Chile. It was named by a British sailor in 1829 after Dynevor Castle in Wales, based on the resemblance of its summit to a fortress.
Its access is quite harsh due to the nature that all roads end about 30 km from it, and the rest of the way must be done either on a 4×4 vehicle, motorcycle, horse or on foot, either way the appropriate track is just by the shore, not through the woods, as they are too dense. (Full article...) -

The Dry Andes (Spanish: Andes áridos) is a climatic and glaciological subregion of the Andes. Together with the Wet Andes it is one of the two subregions of the Argentine and Chilean Andes. The Dry Andes runs from the Atacama Desert in northern Chile and Northwest Argentina south to a latitude of 35°S in Chile. In Argentina the Dry Andes reaches 40°S due to the leeward effect of the Andes. According to Luis Lliboutry
the Dry Andes can be defined by the distribution of penitentes. The southernmost well-developed penitentes are found on Lanín Volcano.
Rock glaciers occur in parts of the Dry Andes, but are lacking in the more southern Wet Andes. In the Dry Andes, ordinary glaciers develop usually at higher altitudes than rock glaciers. Around Aconcagua rock glaciers reach altitudes as a low as 900 m a.s.l. (Full article...) -
Telmatobius is a genus of frogs native to the Andean highlands in South America, where they are found in Ecuador, Peru, Bolivia, northwestern Argentina and northern Chile. It is the only genus in the family Telmatobiidae. Some sources recognize Batrachophrynus as a valid genus distinct from Telmatobius. (Full article...) -
Quilotoa (Spanish pronunciation: [kiloˈto.a]) is a water-filled crater lake and the most western volcano in the Ecuadorian Andes. The 3-kilometre (2 mi)-wide caldera was formed by the collapse of this dacite volcano following a catastrophic VEI-6 eruption about 800 years ago, which produced pyroclastic flows and lahars that reached the Pacific Ocean, and spread an airborne deposit of volcanic ash throughout the northern Andes. This last eruption followed a dormancy period of 14,000 years and is known as the 1280 Plinian eruption. The fourth (of seven) eruptive phase was phreatomagmatic, indicating that a Crater lake was already present at that time. The caldera has since accumulated a 250-metre-deep (820 ft) crater lake, which has a greenish color as a result of dissolved minerals. Fumaroles are found on the lake floor and hot springs occur on the eastern flank of the volcano.
Quilotoa is a site of growing popularity. The route to the "summit" (the small town of Quilotoa) is generally traveled by hired truck or bus from the town of Zumbahua 17 kilometres (11 mi) to the South, or more commonly by bus from Latacunga. Visitors have to pay two US dollars each to enter Quilotoa. There are a number of simple hostels in the immediate area offering services such as mules and guides. Activities include a four to five-hour hike around the caldera (whose diameter is just over 3 kilometres (2 mi)). The caldera rim is highly irregular and reaches its maximum elevations 3,810 metres (12,500 ft) to the N, 3,894 metres (12,776 ft) to the NW and 3,915 metres (12,844 ft) to the SE, at three lava domes. The 10-kilometre (6 mi) hike is sandy and steep in places and can be quite taxing, particularly if there is fog. (Full article...) -
Nevado Tres Cruces is a massif of volcanic origin in the Andes Mountains on the border of Argentina and Chile. It has two main summits, Tres Cruces Sur at 6,748 metres (22,139 ft) and Tres Cruces Centro at 6,629 m (21,749 ft) and a third minor summit, Tres Cruces Norte 6,030 m (19,780 ft). Tres Cruces Sur is the sixth highest mountain in the Andes.
The volcano has an extended history of activity, going back at least 1.5 million years. A number of lava domes surround the complex and a number of craters lie on its summits. The main volcano is of rhyodacitic composition and has generated two major ignimbritic eruptions, one 1.5 million years ago and a second 67,000 years ago. The last eruption was 28,000 years ago, but the volcano is a candidate source for a Holocene eruption and could erupt again in the future. (Full article...) -
Los Nevados National Natural Park (Spanish: Parque Nacional Natural Los Nevados) is a national park located in the Cordillera Central of the Colombian Andes. The park features Colombia's highest and northernmost active volcanoes including the glacier-capped Nevado del Ruiz, Nevado del Tolima, and Nevado de Santa Isabel, and the formerly glaciated superpáramo peaks (paramillos) of Cisne, Santa Rosa and Quindío. Other elevated structures of volcanic origin within the park are Alto La Piraña, La Olleta, Cerro España, and the Peñas de Caracoli. Cerro Bravo and Cerro Machín are located outside the park but part of the same volcanic region.
The park is located in the departments of Caldas, Quindío, Risaralda, Tolima and spans between the municipalities Manizales, Villamaría, Santa Rosa de Cabal, Pereira, Salento, Villahermosa, Anzoátegui, Santa Isabel, Murillo, Ibagué and Casabianca. (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 for the Paramount Pictures production logo. (Full article...) -
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...) -
Misti is a dormant volcano located in the Andes mountains in southern Peru, rising above Peru's second-largest city, Arequipa. It is a conical volcano with two nested summit craters, the inner one of which contains a volcanic plug or lava dome with active fumaroles. The summit of the volcano lies on the margin of the outer crater and is 5,822 metres (19,101 ft) above sea level. Snow falls on the summit during the wet season, but does not persist; there are no glaciers. The upper slopes of the volcano are barren, while the lower slopes are covered by bush vegetation.
The volcano developed over four different stages. During each stage, lava flows and lava domes built up a mountain, whose summit then collapsed to form a caldera. The volcano is part of a volcano group with Chachani to the northwest and Pichu Pichu to the southeast, and developed on top of a basement formed by numerous Miocene-Pliocene ignimbrites and volcano-derived debris. Numerous intense explosive eruptions took place during the last 50,000 years and covered the surrounding terrain with tephra. The last two significant eruptions were 2,000 years ago and in 1440–1470 AD; since then, phases of increased fumarolic activity have sometimes been mistaken for eruptions. (Full article...) -
The Junin grebe (Podiceps taczanowskii), also known as Junin flightless grebe or puna grebe, is a species of grebe endemic to Lake Junin in the Andean highlands of Junin in west-central Peru. An endangered species, the current population is estimated at 300–400 individuals, including 140–320 adults. (Full article...) -
Antisana is a stratovolcano of the northern Andes, in Ecuador. It is the fourth highest volcano in Ecuador, at 5,753 metres (18,875 ft), and is located 50 kilometres (31 mi) SE of the capital city of Quito.
Antisana presents one of the most challenging technical climbs in the Ecuadorian Andes. Next to the Pichincha, Cotopaxi, Tungurahua and Chimborazo, the Antisana belongs to the five volcanic mountains that the Prussian-born explorer Alexander von Humboldt tried to climb in 1802 during his American journey. In 1965, the American climber Edwin Bernbaum alongside two Ecuadorean climbers, Rómulo Pazmino and Leonardo Droira, made the first ascent of South Antisana. (Full article...) -
The guanaco (/ɡwɑːˈnɑːkoʊ/ ghwuah-NAH-koh; Lama guanicoe) is a camelid native to South America, closely related to the llama. Guanacos are one of two wild South American camelids; the other species is the vicuña, which lives at higher elevations. (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...) -
Lake Titicaca (/tɪtɪˈkɑːkə/; Spanish: Lago Titicaca [ˈlaɣo titiˈkaka]; Quechua: Titiqaqa and Aymara: Titiqaqa) is a large freshwater lake in the Andes mountains on the border of Bolivia and Peru. It is often called the highest navigable lake in the world. Titicaca is the largest lake in South America, both in terms of the volume of water and surface area. It has a surface elevation of 3,812 m (12,507 ft). (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...) -
Acotango is the central and highest of a group of stratovolcanoes straddling the border of Bolivia and Chile. It is 6,052 metres (19,856 ft) high. The group is known as Kimsa Chata and consists of three mountains: Acotango, Umurata (5,730 metres (18,799 ft)) north of it and Capurata (5,990 metres (19,652 ft)) south of it.
The group lies along a north–south alignment. The Acotango volcano is heavily eroded, but a lava flow on its northern flank is morphologically young, suggesting Acotango was active in the Holocene. Later research has suggested that lava flow may be of Pleistocene age. Argon-argon dating has yielded ages of 192,000±8,000 and 241,000±27,000 years on dacites from Acotango. Glacial activity has exposed parts of the inner volcano, which is hydrothermally altered. Glacial moraines lie at an altitude of 4,200 metres (13,800 ft) but a present ice cap is only found past 6,000 metres (20,000 ft) of altitude. (Full article...) -
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...) -
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...) -
The Titicaca orestias, Lake Titicaca orestias, or Lake Titicaca flat-headed fish (Orestias cuvieri), also known by its native name amanto, is a likely extinct freshwater killifish from Lake Titicaca in South America. It belongs in the pupfish genus Orestias, endemic to lakes, rivers and streams in the Andean highlands. With a total length of up to 27 cm (10.6 in), it was the largest member in that genus. In the hope that an undiscovered population remains, it is listed as Critically Endangered, possibly extinct by the IUCN. Despite its common name, it is not the only Orestias from Lake Titicaca.
Its mouth was nearly turned upwards, thereby giving the flat head a concave shape. The head took up nearly a third of the whole body length. The upperside was greenish-yellow to umber. The lower jaw was black. Its scales were oddly light coloured at their centre. The scales of the young were blotched. (Full article...) -
Cerro Galán is a caldera in the Catamarca Province of Argentina. It is one of the largest exposed calderas in the world and forms part of the Central Volcanic Zone of the Andes, one of the three volcanic belts found in South America. One of several major caldera systems in the Central Volcanic Zone, the mountain is grouped into the Altiplano–Puna volcanic complex.
Volcanic activity at Galán is the indirect consequence of the subduction of the Nazca Plate beneath the South America Plate, and involves the infiltration of melts into the crust and the formation of secondary magmas which after storage in the crust give rise to the dacitic to rhyodacitic rocks erupted by the volcano. (Full article...) -
Monte Pissis is an extinct volcano on the border of the La Rioja and Catamarca provinces in Argentina, 25 km (16 mi) to the east of the Chilean border and about 550 km (340 mi) north of Aconcagua. The mountain is the second-tallest volcano in the world and the third-highest mountain in the Western Hemisphere.
Monte Pissis is named after Pedro José Amadeo Pissis, a French geologist who worked for the Chilean government.
Due to its location in the Atacama Desert, the mountain has very dry conditions but features an extensive glacier, with crevasses, which is unique in the region. The peak is the highest summit on Earth without a permanent glacier. (Full article...) -
Chinchilla refers to either of two species (Chinchilla chinchilla and Chinchilla lanigera) of crepuscular rodents of the parvorder Caviomorpha, and are 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.
The chinchilla has 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...)
