Sierras Pampeanas
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 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.
