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.
Huallanca mountain range
The Huallanca mountain range (possibly from Quechua, "wallanka" mountain range; a cactus plant ("Opuntia subulata"); also called Chaupi Janca or Shicra Shicra (possibly from Quechua "sikra" woven basket) lies in the Andes of Peru. It is located in the Ancash Region, Bolognesi Province. The Huallanca mountain range is a small range southeast of the Cordillera Blanca and north of the Huayhuash mountain range extending between 9°52' and 10°03'S and 76°58' and 77°04'W for about 19 km in a northeasterly direction.
