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.
Tricontinental Chile
Continental Chile corresponds to the strip of territory along the southwestern coast of South America and its adjacent islands. Almost the entire population lives in continental Chile, which extends from 17°30’ S, at the border with Peru and Bolivia, to the Diego Ramírez Islands at 56°30’ S. The maximum width of is at 52°21’ S, at the Strait of Magellan, whilst the minimum width is at 31°37’ S between Punta Amolanas and Paso de la Casa de Piedra.
