sierras

The Sierras Pampeanas (also called Central Sierras or Pampas Sierras) (English: Pampas Mountains) is a geographical region of Argentina.
The Sierras Pampeanas are a chain of mountains that rise sharply from the surrounding pampa region of Northwest Argentina. They run parallel to the Andes Mountains and their crest line is some 540 km (340 mi) east of the Andes crest line (running from 29° to 35° S latitude at about 65° W longitude). They cross into seven Argentina provinces: San Luis, San Juan, Córdoba, La Rioja, Catamarca, Santiago del Estero and Tucumán.
