The Far North is the area between the northern boundary of the country and the parallel 26° S, covering the first three regions. It is characterized by the presence of the Atacama desert, the most arid in the world. The desert is fragmented by streams that originate in the area known as the pampas Tamarugal. The Andes, split in two and whose eastern arm runs through Bolivia, has a high altitude and volcanic activity, which has allowed the formation of the Andean altiplano and salt structures as the Salar de Atacama, due to the gradual accumulation of sediments over time.
