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.
Cordillera Riesco
The Cordillera Riesco is a mountain range
located in the Chilean Patagonia to the west of Puerto Natales. It extends in north-south direction on the eastern shore of the Fjord of the Mountains and parallel to the Cordillera Sarmiento. The rock towers of the "Grupo La Paz" are the centerpiece of this mountain range. The range includes the Cerro Toro formation, within which the Cueva del Milodon Natural Monument is situated; this monument comprises a cave complex where remains of the extinct Giant sloth have been recovered along with evidence of occupation by prehistoric man.
