Pampean Sierras
mountains, Argentina
Quick Summary
The Pampean Sierras are a series of low mountain ranges located in the northwestern part of the Pampas region of Argentina. These sierras are not as high or as rugged as the Andes Mountains, which form Argentina's western border. The Pampas themselves are vast plains that stretch across central Argentina. The Pampean Sierras are a distinct geographic feature within this otherwise flat landscape, with some areas appearing perfectly flat apart from these few sierras.123
