Chilean Coast Range
The Chilean Coastal Range () is a mountain range that runs from north to south along the Pacific coast of South America parallel to the Andean Mountains, extending from Morro de Arica in the north to Taitao Peninsula, where it ends at the Chile Triple Junction, in the south. The range has a strong influence on the climate of Chile since it produces a rain shadow to the east. Because of this the vegetation growing on the seaward slopes is much more exuberant than in the interior. Compared to the coastal lowlands and the Intermediate Depression it is sparsely populated with land use varying from protected areas to grazing and silviculture. The range is present in all Chilean regions except for Coquimbo Region and Magallanes Region.
Camino de los chilenos
Rastrillada de los chilenos or Camino de los chilenos (Spanish for road of the Chileans) were a group of routes in Patagonia used by Mapuches and related araucanized tribes to head cattle stolen during malones from Argentina to Chile across the Andes. Camino de los chilenos ran a length of about 1000 km from the Buenos Aires Province to the mountain passes of Neuquén Province. The cattle were traded in Chile for weapons and alcoholic beverages. This trade has been pointed out as the single most important cause of the war that affected the southern provinces of Argentina during large parts of the 19th century. Therefore, the demand for cattle by Chilean merchants was fueling the conflict in Argentina. To counter the cattle raids a trench called Zanja de Alsina was built by Argentina in the pampas in the 1870s. The use of this trade route effectively ended with the Conquest of the Desert (1876-1878) carried out by the Argentine Army.
