The Atacama Desert is a plateau in South America, covering a 1,000 km strip of land on the Pacific coast, west of the Andes mountains. It is, according to many publications, the driest desert in the world. The Atacama occupies 105,000 km2 in northern Chile, composed mostly of salt basins (salares), sand, and felsic lava flows towards the Andes. Laguna Lejía, shown on the postcard I got is a salt lake located in the Altiplano of the Antofagasta Region of northern Chile. The landscape of the area is dominated by the volcanoes Chiliques, Lascar, Aguas Calientes and Acamarachi.
