Chile
The Chilean relief consists of the central depression, which crosses the country longitudinally, flanked by two mountain ranges that make up about 80% of the territory: the Andes mountains to the east-natural border with Bolivia and Argentina in the region of Atacama and the Coastal Range west-minor height from the Andes. Chile's highest peak is the Nevado Ojos del Salado, at 6891.3 m, which is also the highest volcano in the world. The highest point of the Coastal Range is Vicuña Mackenna, at 3114 meters, located in the Sierra Vicuña Mackenna, the south of Antofagasta. Among the coastal mountains and the Pacific is a series of coastal plains, of variable length, which allow the settlement of coastal towns and big ports. Some areas of the plains territories encompass territory east of the Andes, and the Patagonian steppes and Magellan, or are high plateaus surrounded by high mountain ranges, such as the Altiplano or Puna de Atacama.
Central Chile
Central Chile is one of the five main geographical zones in which Chile is divided. The Chilean Central Valley lies between the Coastal range ("Cordillera de la Costa") and the Andes Mountains. To the north is the semi-desert region known as El Norte Chico, (the "little north"), which lies between 28° and 32° south latitude. To the south lies the cooler and wetter Valdivian temperate rain forests ecoregion, in Los Lagos Region; (the latter includes most of South America's temperate rain forests). The Central valley is a fertile region and the agricultural heartland of Chile.
