The Uchusuma River originates from the Peruvian Altiplano, crosses the northern tip of Chile and reaches Bolivia where empties into Mauri River.
The geography of Bolivia includes the Eastern Andes Mountain Range which bisects Bolivia roughly from north to south. To the east of that mountain chain are lowland plains of the Amazon Basin, and to the west is the Altiplano which is a highland plateau where Lake Titicaca is located. Bolivia's geography has features similar to those of Peru which abuts Bolivia's northwest border; like Bolivia, Peru is bisected from north to south by the Eastern Andes Mountains, and these two countries share Lake Titicaca which is the highest navigable lake on Earth. Unlike Peru, however, Bolivia is one of the two landlocked countries in South America, the other being Paraguay which is located along Bolivia's southeast border.
The Antofagasta Region is one of Chile's sixteen first-order administrative divisions. It comprises three provinces, Antofagasta, El Loa and Tocopilla. It is bordered to the north by Tarapacá and by Atacama to the south and is the second-largest region of Chile. To the east it borders Bolivia and Argentina. The capital of the region is the port city of Antofagasta, another important city being Calama. The main economic activity is copper mining in the giant porphyry copper systems located inland.
The Aymara or Aimara people are an indigenous nation in the Andes and Altiplano regions of South America; about 1 million live in Bolivia, Peru and Chile. Their ancestors lived in the region for many centuries before becoming a subject people of the Inca in the late 15th or early 16th century, and later of the Spanish in the 16th century. With the Spanish American Wars of Independence (1810–25), the Aymaras became subjects of the new nations of Bolivia and Peru. After the War of the Pacific (1879–83), Chile annexed territory occupied by the Aymaras.
The Altiplano, Collao or Andean Plateau, in west-central South America, is the area where the Andes are the widest. It is the most extensive area of high plateau on Earth outside Tibet. The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, and its southern parts lie in Chile and Argentina.
The Tarapacá Region is one of Chile's 16 first-order administrative divisions. It borders the Chilean Arica and Parinacota Region to the north, Bolivia's Oruro Department on the east, the Antofagasta Region on the south and the Pacific Ocean on the west. The port city of Iquique is the region's capital.
The Arica y Parinacota Region is one of Chile's 16 first order administrative divisions. It borders Peru to the north, Bolivia to the east and Chile's Tarapacá Region to the south. It is also the country's newest region, created under Law No. 20,175. It became operational on October 8, 2007. Chile's former Tarapacá region was a former Peruvian province, which was occupied by Chile under the 1883 Treaty of Ancón at the close of the War of the Pacific, and then formally annexed in 1929 by the Treaty of Lima.
There are several Altiplanos in the Americas. Altiplano may refer to:
Hilarión Daza Groselle was President of Bolivia from 1876 to 1879.
Llajua or llajwa is a chili sauce prepared from locotos hot chili peppers, and tomatoes; sometimes onions are added to the mix. One or two seasoning herbs could be added, depending on the region and taste: quirquiña in Cochabamba and wakataya in the Altiplano and other valleys of Bolivia. It is preferably prepared on a grinding stone called a batán, which can be found in most Bolivian households of Cochabamba and Altiplano. In the absence of a batan, it can be prepared in a blender.
The Norte Grande is one of the five natural regions into which CORFO divided continental Chile in 1950. It borders Peru to the north, the Pacific Ocean to the west, the Altiplano, Bolivia and Argentina to the east, and the Copiapó River to the south, beyond which lies the Norte Chico natural region.
The Lauca River is a binational river. It originates in the Chilean Altiplano of the Arica and Parinacota Region, crosses the Andes and empties into Coipasa Lake in Bolivia.
The Andean gull is a species of gull in the family Laridae. As is the case with many gulls, it has traditionally been placed in the genus Larus. It is found in the Andes in mountainous regions of Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. It is unusual for a gull in that it breeds inland in mountain areas. It may be variously found around rivers, freshwater lakes, saline marshes, and pastureland.
The following outline is provided as an overview of and topical guide to South America.
The Cosapilla River is a river of Chile and Bolivia and is part of the boundary. It is also called Caquena and, in Bolivia, Cosapa. From its source in the Parinacota Province, the river flows north, is part of the Chile-Bolivia boundary and then flows in the Bolivian Department of Oruro.
The Andean orogeny is an ongoing process of orogeny that began in the Early Jurassic and is responsible for the rise of the Andes mountains. The orogeny is driven by a reactivation of a long-lived subduction system along the western margin of South America. On a continental scale the Cretaceous and Oligocene were periods of re-arrangements in the orogeny. Locally the details of the nature of the orogeny varies depending on the segment and the geological period considered.
The geology of Bolivia comprises a variety of different lithologies as well as tectonic and sedimentary environments. On a synoptic scale, geological units coincide with topographical units. The country is divided into a mountainous western area affected by the subduction processes in the Pacific and an eastern lowlands of stable platforms and shields. The Bolivian Andes is divided into three main ranges; these are from west to east: the Cordillera Occidental that makes up the border to Chile and host several active volcanoes and geothermal areas, Cordillera Central once extensively mined for silver and tin and the relatively low Cordillera Oriental that rather than being a range by its own is the eastern continuation of the Central Cordillera as a fold and thrust belt. Between the Occidental and Central Cordillera the approximately 3,750-meter-high Altiplano high plateau extends. This basin hosts several freshwater lakes, including Lake Titicaca as well as salt-covered dry lakes that bring testimony of past climate changes and lake cycles. The eastern lowlands and sub-Andean zone in Santa Cruz, Chuquisaca, and Tarija Departments was once an old Paleozoic sedimentary basin that hosts valuable hydrocarbon reserves. Further east close to the border with Brazil lies the Guaporé Shield, made up of stable Precambrian crystalline rock.
Aymara may refer to:
Kunturiri is a volcano in the Andes on the border of Bolivia and Chile which rises up to 5,762 metres (18,904 ft). On the Chilean side it is located in the Arica and Parinacota Region and on the Bolivian side in the Oruro Department, Sajama Province, Curahuara de Carangas Municipality, Sajama Canton as well as in the La Paz Department, Pacajes Province, Calacoto Municipality, Ulloma Canton.
Lauca is a 5,140 metres (16,860 ft) high andesitic stratovolcano in the Central Volcanic Zone of the Andes on the Altiplano in northern Chile. Administratively it is located in Putre, Arica y Parinacota Region. The volcano was active during the Late Miocene from 10.5 million years ago onwards. A major ignimbrite collapsed the volcano in the Late Pliocene.
The Battle of Río Grande was a small military engagement that took place on 10 September 1879, during the War of the Pacific. A picket of Chilean soldiers and a Bolivian montonera clashed in Rio Grande, around San Pedro de Atacama. Bolivians are defeated, which eliminates local resistance to Chilean occupation in the Litoral Department.
