Zapaleri
Zapaleri is a volcano whose summit is the tripoint of the borders of Argentina, Bolivia and Chile. A number of railways are in the area. It is part of Potosí Department (Bolivia), Jujuy Province (Argentina), and Antofagasta Region (Chile). The volcano formed on top of the 2.89 mya Tara Ignimbrite from the Guacha caldera and the basement beneath the volcano is formed from Cretaceous and Tertiary rocks affected by tectonic deformation. Volcanic rocks are andesite, basalt, dacite and rhyolite. Late Cretaceous rocks are also found in the area, as are Pleistocene shoshonite volcanic rocks. The Bolivian portion of the mountain is protected within Eduardo Avaroa Andean Fauna National Reserve. Moreover, it is close to the sector ''Salar de Tara-Salar de Aguas Calientes'' of Los Flamencos National Reserve, Chile. Zapaleri is associated with a major source of obsidian Obsidian () is a naturally occurring volcanic glass formed when lava extrusive rock, extruded from a volcano cools r ...

Eduardo Avaroa Andean Fauna National Reserve
The Eduardo Avaroa Andean Fauna National Reserve (''Reserva Nacional de Fauna Andina Eduardo Avaroa''; Spanish acronym: REA) is located in Sur Lípez Province. Situated in the far southwestern region of Bolivia, it is the country's most visited protected area. It is considered the most important protected area in terms of tourist influx in the Potosí Department. Located at an altitude between and in Bolivia, it extends over an area of and includes the Laguna Colorada National Wildlife Sanctuary. Categorized under IUCN Category IV, it is primarily for the protection of birds that inhabit the different lagoons in the reserve. The reserve protects part of the Central Andean dry puna (oligothermic) ecoregion. The reserve's major attractions are erupting volcanoes, hot springs, geysers, lakes, fumaroles, mountains and its three endemic species of flamingos in particular. History Established in 1973, the national park is named after Eduardo Avaroa (1838–1879), the Bolivian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bolivia–Chile Border
The Bolivia–Chile border is an international border of South America. It separates Bolivia from Chile along Cordillera Occidental on the western edge of the Altiplano Plateau. There is an ongoing dispute about the nature of Silala River and Chile's use of its waters. Since 2021 the Bolivia–Chile border has been a major point of entry of irregular Venezuelan migrants into Chile. Migrants are aided in the crossing by human smugglers. Irregular migration has been particularly troublesome for the Chilean border town of Colchane. Indigenous Aymara communities live on both sides of the border.

It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the eas ...

Argentina–Chile Border
The Argentina–Chile border is the longest international border of South America and the third longest in the world after the Canada–United States border and the Kazakhstan–Russia border. With a length of , it separates Argentina from Chile along the Andes and on the islands of Tierra del Fuego. However, there are some border disputes, particularly around the Southern Patagonian Ice Field. It is the largest border of the two countries, beating the Argentina–Paraguay and Chile–Bolivia, Argentina's and Chile's second largest borders, respectively. Plot The northern end of the border is a tripoint it forms with those at the Argentina–Bolivia border and the Bolivia-Chile border in the arid Puna de Atacama plateau. The border extends south until reaching the sea at the same place the Strait of Magellan meets the Atlantic Ocean. Further south the border on the Isla Grande de Tierra del Fuego follows a meridian separating the island into two. This boundary reaches ...

Cerro Guacha
Cerro Guacha is a Miocene caldera in southwestern Bolivia's Sur Lípez Province. Part of the volcanic system of the Andes, it is considered to be part of the Central Volcanic Zone (CVZ), one of the three volcanic arcs of the Andes, and its associated Altiplano-Puna volcanic complex (APVC). A number of volcanic calderas occur within the latter. Cerro Guacha and the other volcanoes of that region are formed from the subduction of the Nazca plate beneath the South America plate. Above the subduction zone, the crust is chemically modified and generates large volumes of melts that form the local caldera systems of the APVC. Guacha is constructed over a basement of sediments. Two major ignimbrites, the 5.6-5.8 mya Guacha ignimbrite with a volume of and the 3.5-3.6 mya Tara ignimbrite with a volume of were erupted from Cerro Guacha. More recent activity occurred 1.7 mya and formed a smaller ignimbrite with a volume of . The larger caldera has dimensions of with a rim altitude of . ...

Border Tripoints
Borders are usually defined as geographical boundaries, imposed either by features such as oceans and terrain, or by political entities such as governments, sovereign states, federated states, and other subnational entities. Political borders can be established through warfare, colonization, or mutual agreements between the political entities that reside in those areas; the creation of these agreements is called boundary delimitation. Some borders—such as most states' internal administrative borders, or inter-state borders within the Schengen Area—are open and completely unguarded. Most external political borders are partially or fully controlled, and may be crossed legally only at designated border checkpoints; adjacent border zones may also be controlled. Buffer zones may be setup on borders between belligerent entities to lower the risk of escalation. While ''border'' refers to the boundary itself, the area around the border is called the frontier.

Headlands Of Chile
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Chile
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 and ...

Landforms Of Jujuy Province
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.
