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.
Transverse Valleys
The Transverse Valleys (Spanish: "Valles transversales") are a group of transverse valleys in the semi-arid northern Chile. They run from east to west (traversing Chile), being among the most prominent geographical features in the regions they cross. They are located in the Chilean regions of Valparaíso, Coquimbo, and Atacama. They share some characteristics, such as reaching the Pacific Ocean without passing through an Intermediate Depression, being rather deep and dissecting the landscape, concentrating most agriculture and population in the areas through which they pass, and being intensively cultivated. They are one of the defining elements the Chilean natural region of Norte Chico. The area of the Transverse Valleys spans roughly a length of 600 km from north to south.
