	Geography of Bolivia - Wikipedia, the free encyclopedia
		Stretching in a broad arc across western Bolivia, the Andes define the country's three geographic zones: the mountains and Altiplano in the west, the subtropical Yungas and temperate valleys of the eastern mountain slopes (the western part of the Amazon Rainforest), and the tropical lowlands or plains (llanos) of the eastern lowlands, or Oriente.
		The Cordillera Occidental is a chain of dormant volcanoes and solfataras, volcanic vents emitting sulfurous gases.
		All of the Cordillera Occidental region is sparsely populated, and the south is virtually uninhabited.

	BOLIVIA - Online Information article about BOLIVIA
		The cordilleras, divided into two great parallel chains, with flanking ranges and spurs to the east, reach their greatest breadth at this point and form the massif of the Andean system.
		The eastern rampart of this great plateau is formed by the Cordillera Oriental, which ex-tends north-west into Peru under the name of Carabaya, and south to the frontier in broken ranges, one of which trends south-east in the vicinity of Sucre.
		On the west side of the Cordillera, which extracts the moisture from the prevailing easterly winds, the elevated plateaus have a limited rainfall in the north, which diminishes toward the south until the surface becomes absolutely barren.

		The arc consists of three main parallel ranges, known as the Cordillera Occidental (Western Cordillera), the Cordillera Central (Central Cordillera), and the Cordillera Oriental (Eastern Cordillera).
		The Cordillera Oriental divides into the Cordillera Mérida, which extends along the east coast of Lake Maracaibo in Venezuela, and the Sierra de Perijá, which extends to the west of Lake Maracaibo along the borders of Colombia and Venezuela.
		The two main ranges of the central Andes, which are also known as the Cordillera Occidental and the Cordillera Oriental, enclose the Altiplano, an extensive plateau in Bolivia and southern Peru between 3,600 to 4,000 m (12,000 to 14,000 ft) above sea level.

		Turning to the Cordillera Occidental and taking the principal peaks in order from south to north, the first to claim attention is Chimborazo (from Chimpu-raza, mountain of snow), the highest summit of Ecuador, and once believed to be the culminating point of the Andes.
		In the intra-andine depression, between the East and West Cordilleras, recent deposits with plant remains occur near Loja, and tothe north-east of Cuenca is a sandstone containing mercury ores, somewhat similar to that of Peru.
		The best grazing lands are on the lower elevations west of the Cordilleras in certain districts of the plateau and on the slopes of some of the higher Andes, as on Chimborazo and Antisana.

		Of the three ranges, the nonvolcanic Cordillera Occidental, which forms the barrier between the Cauca valley and the rain-drenched Pacific coast, is the lowest and least populated.
		The Cordillera Central is the highest of the Andean ranges of Colombia, rising to an average height of 10,000 feet (3,000 metres).

		In the south, a western Cordillera Occidental and a central Cordillera Central are separated by a rift valley enclosing the Cauca River.
		The Cordillera Occidental parallels the sparsely populated Pacific coast and recedes, as does the Cordillera Central, into the Caribbean lowlands in the northwest.
		To the southeast of the Cordillera Oriental lies the vast, barely populated lowland, which consists of the Llanos (Orinoquia) and Amazonia regions (together accounting for three-fifths of the country's land area) and which is drained by the Orinoco (northern half) and the Amazon rivers.

		To the west of the inter-Andean valley, the Cordillera Occidental predominantly consists of fault-bounded Cretaceous-Tertiary accreted oceanic terranes, comprising basaltic volcanic and volcaniclastic rocks, which are the main focus of this study.
		The Cordillera Occidental is intruded by Mid-Eocene to Late Tertiary granites and is overlain by post Late Eocene continental arc volcanic rocks.
		As a result of a preliminary mapping survey (carried out by BGS and the then Ecuadorian Geological Survey (DGGM)) that included much of the Cordillera Occidental, Henderson (1979) proposed that the basic volcanic rocks of the Cordillera and the Costa were of a different age and origin.

		Two of the species appear closely related to species found on the Amazonian slopes of the Andes in Colombia and/or Ecuador (one from Western Antioquia is the sister species of E. ganonotus and the other from the Serranía de los Paraguas is the sister species of E. pugnax).
