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...)

Tupungato, one of the highest mountains in the Americas, is a massive Andean lava dome dating to Pleistocene times. It lies on the Argentina–Chile border, between the Chilean Metropolitan Region (near a major international highway about 80 km (50 mi) east of Santiago) and the Argentine province of Mendoza, about 100 km (62 mi) south of Aconcagua, the highest peak of both the Southern and Western hemispheres. Immediately to its southwest is the active Tupungatito volcano (literally, little Tupungato), which last erupted in 1987.
Tupungato Department, an important Argentine wine-producing region in Mendoza province, is named for the volcano. Recent Chilean mapping indicates it has a height of 6635m. (Full article...) -
Yerupajá is a mountain of the Huayhuash mountain range in west central Peru, part of the Andes. It is located at Áncash, Bolognesi Province, Lauricocha Province. At 6,635 metres (21,768 ft) (other sources: 6,617 m (21,709 ft)) it is the second-highest in Peru and the highest in the Huayhuash mountain range. The summit is the highest point in the Amazon River watershed, and was first reached in 1950 by Jim Maxwell and Dave Harrah, and its northern peak (Yerupajá Norte) in 1968 by the Wellingtonian Roger Bates and Graeme Dingle. Many visitors consider Yerupajá to be the most spectacular peak in South America.
There have been only a few successful ascents of the peak because it is one of the hardest Andean high peaks to climb. The most popular route is the southwest face. The approach is normally made from Huaraz southwards via Chiquián and Jahuacocha. (Full article...) -

Huandoy (probably from Quechua wantuy, to transfer, to transpose, to carry, to carry a heavy load) or Tullparaju (possibly from Quechua tullpa rustic cooking-fire, stove, rahu snow, ice, mountain with snow) is a mountain located inside Huascarán National Park in Ancash, Peru. It is the second-tallest peak of the Cordillera Blanca section of the Andes, after Huascarán. These two peaks are rather nearby, separated only by the Llanganuco glacial valley (which contains the Llanganuco Lakes) at 3,846 m asl.
It is a snow-capped mountain with four peaks arranged in the form of a fireplace, the tallest of which is 6,395 m. The four peaks are each over 6,000 m, and are:- Huandoy (6,395 m)
- Huandoy-West (6,356 m)
- Huandoy-South (6,160 m)
- Huandoy-East (6,000 m)

Cayambe or Volcán Cayambe is a volcano in Ecuador, in the Cordillera Central, a range of the Ecuadorian Andes. It is located in Pichincha Province, some 70 km (43 mi) northeast of Quito. It is the third-highest mountain in Ecuador, at an elevation of 5,790 m (18,996 ft) above sea level.
Cayambe, which has a permanent snow cap, is a Holocene compound volcano which last erupted in March 1786. At 4,690 metres (15,387 ft), its south slope is the highest point in the world crossed by the Equator, and the only point on the Equator with snow cover. The ice cap covers an area of about 22 km2 (8 sq mi) and there are glaciers on the eastern flank descending to about 4,400 m (14,400 ft), whereas those on the drier western flank reach about 4,700 m (15,400 ft). The volcano and most of its slopes are within the Cayambe Coca Ecological Reserve. (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 bushland.
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...) -

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...) -
Sierra Nevada, also known as Sierra Nevada de Lagunas Bravas, is a major ignimbrite-lava dome complex which lies in both Chile and Argentina in one of the most remote parts of the Central Andes.
Activity in the complex started in Argentina and formed two stratovolcanoes. Later, 12 or more vents formed, some with craters up to 400 metres (1,300 ft) wide. Lava flows up to 7 kilometres (4.3 mi) long with flow ridges are also found. It covers a total area of 225 km2. Radiometric dating has yielded ages of 1.7 ± 0.4 to 0.431 ± 0.012 million years ago, a lava flow from the neighbouring Azufrera Los Cuyanos volcano that is sometimes considered part of Sierra Nevada is 140,000 years old. Together with Cerro el Condor and Peinado it forms the Culampaja line, a line of volcanoes that reaches Cerro Blanco. Strong seismic attenuation is observed beneath Sierra Nevada. Hydrothermally altered rocks in Sierra Nevada may be the source of sulfate and arsenic in the Juncalito and Negro rivers, and heat sources for regional hot springs. The snowline in the area lies at 5,800 metres (19,000 ft) altitude at Cumbre del Laudo. (Full article...) -
The Nevado del Tolima is a Late Pleistocene to recently active andesitic stratovolcano located in the Tolima department, Colombia. The volcano lies south of Nevado del Ruiz volcano and is situated within the Los Nevados National Natural Park. The volcano, whose most recent activity dates to 1943 and last major eruption around 3600 years ago, overlies the Eocene El Bosque Batholith, dated at 49.1 ± 1.7 Ma. (Full article...) -
Salcantay, Salkantay or Sallqantay (in Quechua) is the highest peak in the Vilcabamba mountain range, part of the Peruvian Andes. It is located in the Cusco Region, about 60 km (40 mi) west-northwest of the city of Cusco. It is the 38th-highest peak in the Andes and the twelfth-highest in Peru. However, as a range highpoint in deeply incised terrain, it is the second most topographically prominent peak in the country, after Huascarán.
Salcantay's proximity to Machu Picchu makes trekking around it an alternative to the oversubscribed Inca Trail; this is known as the Salkantay trek. (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...) -
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...) -
Laram Q'awa (Aymara larama blue, q'awa little river, ditch, crevice, fissure, gap in the earth, "blue brook" or "blue ravine", Hispanicized spellings Laram Khaua, Larancagua) is a 5,182-metre-high (17,001 ft) mountain in the Andes. According to the Bolivian IGM map 1:50,000 'Nevados Payachata Hoja 5739-I' it is situated on Bolivian terrain in the La Paz Department, Pacajes Province (Charaña Municipality), at the border with Chile. It lies north-west of the mountains Kunturiri, Phaq'u Q'awa and another mountain on the border named Laram Q'awa (Laram Khaua). One of three different rivers of this area called Kunturiri (Condoriri) originates north-east of the mountain near Phaq'u Q'awa. It flows in a bow along the northern slopes of Laram Q'awa towards Chile. (Full article...) -
Azufral is a stratovolcano located in the department of Nariño in southern Colombia, 12 km (7 mi) west of the town of Túquerres. It is the only volcano of the Western Ranges of the Colombian Andes. Its name derives from the Spanish word for sulfur, azufre. The volcano is considered semi-dormant but there are numerous fumaroles in the summit crater. The summit of the volcano has an altitude of 4,070 metres (13,350 ft), and the north-western side of the crater contains a crescent-shaped lake named Laguna Verde (English: Green Lake) at 3,970 m (13,025 ft). The lake is 1,100 m (0.68 mi) long and 600 metres (2,000 ft) wide. and its bright green color is a result of the sulfur and iron-based deposits in the crater. There are also two other much smaller lakes in the crater, Laguna Negra (English: Black Lake) and Laguna Cristal (English: Crystal Lake).
The volcano lies within a nature reserve, the Reserva Natural del Azufral, created in 1990. The reserve covers an area of 5,800 hectares (58 km2) and is free of charge to enter. As Azufral is semi-dormant, there are no restrictions on ascending the volcano and visiting Laguna Verde: there is a road that climbs to within 1.5 kilometers (1 mi) from the summit, and the remaining distance can be covered on foot via a trail.

El Altar or Capac Urcu (possibly from Kichwa kapak principal, great, important / magnificence, urku mountain) is an extinct volcano on the western side of Sangay National Park in Ecuador, 170 km (110 mi) south of Quito, with a highest point of 5,319 m (17,451 ft). Spaniards named it so because it resembled two nuns and four friars listening to a bishop around a church altar. In older English sources it is also called The Altar. (Full article...) -
Doña Juana (Spanish: Volcán Doña Juana) is a stratovolcano, located within the Doña Juana-Cascabel Volcanic Complex National Natural Park (Spanish: Parque Nacional Natural Complejo Volcánico Doña Juana-Cascabel) in Nariño, Colombia.
With a previous eruption of VEI 4, Doña Juana is rated as a "large" volcano of "cataclysmic" destructive power. During its last eruption, in 1906, more than 100 people were killed and many houses were destroyed. (Full article...) -
Nevado Sajama ([neˈβaðo saˈxama]; Aymara: Chak Xaña) is an extinct volcano and the highest peak in Bolivia. The mountain is located in Sajama Province, in Oruro Department. It is situated in Sajama National Park and is a composite volcano consisting of a stratovolcano on top of several lava domes. It is not clear when it erupted last but it may have been during the Pleistocene or Holocene.
The mountain is covered by an ice cap, and Polylepis tarapacana trees occur up to 5,000 metres (16,000 ft) elevation. (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...) -
Acamarachi (also known as Pili) is a 6,046-metre (19,836 ft) high volcano in northern Chile. In this part of Chile, it is the highest volcano. Its name means "black moon". It is a volcano in the Central Volcanic Zone of the Andes, a zone of strong volcanic activity during the last million years. Old volcanoes in the area are well-preserved, due to the dry climate.
Acamarachi itself is a cone-shaped volcano with steep upper flanks and a lava dome on its northern side. While there is no indication of historical activity and the flank lava flows are old, some lava flows around the summit crater and a lava coulee north of Acamarachi on the saddle between Acamarachi and Colachi volcano may be postglacial in age. Acamarachi is formed by andesitic and dacitic rocks. (Full article...)
