where cliffs and gullies divide the rolling grassland, is used by farmers to graze hardy mountain cattle.

The Pampas Most of eastern Argentina in South America consists of huge flat grassy plains called the pampas. The greater part of the plain, known as the dry pampa, is a salty, sandy wilderness. However, the eastern edge of the pampas, called the humid pampa, is cooler and well-watered. When Spanish settlers arrived in the region, they raised cattle and herds of semi-wild horses on the humid pampa. Gauchos, the famous cowboys of the plains, tended the cattle and horses. Today, the pampa is devoted mainly to growing wheat, maize, and alfalfa. These crops are used to supplement the grazing for herds of pedigree cattle and sheep.
