Paso De San Francisco
The San Francisco Pass is a pass over the Andes mountains which connects Argentina and Chile. The highest point of this pass is at AMSL. Location The pass is located at and connects the Argentine province of Catamarca with the Atacama Region in Chile. In the Argentine side, route N 60 ascends from Fiambala at AMSL in a deep valley formed by mountains. In the last sinuous , the route climbs from about in Las grutas to more than at the border. On the Chilean side the route CH-31 connects Copiapó with the ChileanArgentine border. On the way it passes next to Maricunga's salt flat on the Nevado Tres Cruces National Park and Laguna Verde. The area is surrounded by volcanoes and high peaks as the Cerro Falso Azufre (), the volcano San Francisco (), the Incahuasi () and highest volcano in the world, Nevado Ojos del Salado (), among others.

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Mountain Passes Of The Andes
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...

Laguna Verde (Chile)
Laguna Verde is a Chilean town in the commune of Valparaíso in Valparaíso Province, Valparaíso Region. The town itself is small and quiet, feeling quite removed from hustle and bustle of nearby Valparaiso. Attractions include secluded beaches and miles of old logging roads perfect for mountain biking. There the people can find very interesting places such as: "Las Canteras" that is a sequence of different water falls and natural pools, "La Playa Chica" that is like a little beach nearby the power plant that operates with coal, "La Caleta Chica" and "La Caleta Grande" that are little spots where fisherman families live and work, "Las Docas" that is a beach with big waves and is a very good spot for fishing and "El Faro" that is located at the end of the gulf and has the Lighthouse that helps the boats that get to Valparaíso.

Cerro Torta
Cerro Torta is a dacitic lava dome in Argentina. Approximately high, it covers an area of with of rocks. Cerro Torta is about 430,000 years old and is part of a recent volcanic series together with Cueros de Purulla and Cerro Blanco. A seismic swarm recorded on the 23 January 2009 at Cerro Torta most likely reflects underground movement of magma, but a source in tectonic faulting close to the dome is also possible. There are also underground anomalies in seismic tomography images. The dome lies in the Central Volcanic Zone of the Andes, in the Ojos del Salado region. It is surrounded by Miocene and Pliocene volcanoes, but there also are Quaternary volcanoes in the area such as Falso Azufre west-southwest and El Peinado north. Peinado and several mafic monogenetic volcanoes form an alignment with Cerro Torta. San Francisco Pass The San Francisco Pass is a pass over the Andes mountains which connects Argentina and Chile.

Ojos Del Salado
Nevado Ojos del Salado is a dormant complex volcano in the Andes on the Argentina–Chile border. It is the highest volcano on Earth and the highest peak in Chile. The upper reaches of Ojos del Salado consist of several overlapping lava domes, lava flows and volcanic craters, with an only sparse ice cover. The complex extends over an area of and its highest summit reaches an altitude of above sea level. Numerous other volcanoes rise around Ojos del Salado. Due to its location near the Arid Diagonal of South America, the mountain has extremely dry conditions, which prevent the formation of glaciers and a permanent snow cover. Despite the arid climate, there is a permanent crater lake about in diameter at an elevation of - within the summit crater and east of the main summit. This is the highest lake of any kind in the world. Owing to its altitude and the desiccated climate, the mountain lacks vegetation. Ojos del Salado was volcanically active during the Pleistocene and Holo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incahuasi
Incahuasi (; 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 above sea level. The volcano consists of a caldera and two stratovolcanoes. Four pyroclastic cones located to the northeast have produced basalt-andesite lava flows that cover an area of . Geography and geology Incahuasi lies on the border between Argentina and Chile, close to Paso San Francisco. A major road crosses the border there. Regional Incahuasi is part of the Central Volcanic Zone of the Andes, together with about 110 other Quaternary volcanoes, and lies in the southern sector of this zone; other volcanic zones in the Andes are the Northern Volcanic Zone, the Southern Volcanic Zone, and the Austral Volcanic Zone. The history of volcanic activity of most of these volcanoes is poorly understood owing to the lack of dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Falso Azufre
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 with the exception of the main crater, which is wide.Grosse, et al. 2018, p. 12 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 long.Grosse, et al. 2018, p. 13 The oldest is known as the Kunstmann edifice on the northwestern side of Falso Azufre; Kunstmann volcano features a wide scar formed by a sector collapse. Falso Azufre with a base surface of 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 h ...
