American Cordillera
The Cordillera continues on through the mountain ranges of Central America in Guatemala, Honduras, Nicaragua, Costa Rica, and Panama, and becomes the Andes Mountains of South America. The Andes with their parallel chains and the island chains off the coast of Chile continue through Colombia, Venezuela, Ecuador, Peru, Bolivia, Argentina, and Chile to the very tip of South America at Tierra del Fuego. The Cordillera continues along the Scotia Arc before reaching the mountains of the Antarctic Peninsula.
Chilean Central Valley
The valley runs an un-interrupted leght of 360 km from Angostura de Pelequén in the north to Bío Bío River (37°40' S) in the south. It broadens from 12 km at Molina (35°05' S) in the north to 74 km in the south at Laja (37°15' S) the relief being gently undulating. Conglomerate of Andean provenance cover large swathes of the Central Valley being less common to the west near the Coast Range. Occasionally the valley contains isolated hills and mountains made up of basement rocks. At the latitudes of Temuco the Coast Range is subdued to such degree the Central Valley coalesces with the coastal plains.
