Geographi
The main feature of the Argentinean Relief is the huge contrast offered by great oriental plains and the imposing Andes Range to the west where the highest mountain of the occidental hemisphere is located- the Aconcagua , 6,959 meters high
In its length from Jujuy to Tierra del Fuego , the Andes Range shows a marvelous variety of landscapes: from Northeast plateau, which are deserts with valleys, narrow paths and colorful hills, to the lakes, woods and glaciers of Patagonia .

In the North, Chaco is a forest area linked to Bermejo , Salado and Pilcomayo Rivers .
Between Paraná and Uruguay Rivers , the Argentinean Mesopotamia (Entre Ríos, Corrientes and Misiones Provinces ) is made up of low hills, lagoons and estuaries which are signs of the old courses of these big rivers. In some areas, immersed in the subtropical forest, there are breakings that favor spectacular phenomena such as Iguazú falls.
In the center of Argentina , the Pampa region is the most extensive and well known area. It has an intense farming and cattle exploitation involving Buenos Aires Province , the Northeast of La Pampa Province and South of Córdoba and Santa Fe Provinces . The landscape is interrupted in the South by the small mountains of Tandil and de la Ventana and, to the west, by Códoba mountains.
To the South, from the Andes to the sea, the sterile and stony patagonic plateau is situated being lashed by wind. The Atlantic litoral, with high cliffs, depicts wavy shapes such as Valdés Peninsula with spectacular settlements of marine animals.
