Atacama Desert, interior region of southern Bolivia, northern Chile, and northwestern Argentina, 8,250-13,200 feet in elevation. Considered the driest desert of the world, the Atacama expands along a series of elongated, flat-bottomed basins, the remnants of shallow lakes of Quaternary Age. Today, on the floors of the desiccated lakes, borax, natural salt, and nitrate deposits are mined. Along intermittent watercourses fed by the icecaps of Andean volcanoes, pastoral communities of Atacameño Indians were established about 5,000 years ago. They were skilled woodcarvers and expert wool and ceramic artisans who traded with the Incas and the Aymara (Tiahuanaco) Indians to the north and the Diaguitas to the south. Several towns in the Atacama Desert, such as Peine, San Pedro de Atacama, and Lasana, still bear the strong cultural imprints of the old Atacameño culture.
