The Cordillera of the Andes borders the Puna to the west, while the Bolivian Cordillera Real bounds it to the east.
These minor ranges, excepting the Zenta, are separated from the Andean masses by comparatively low depressions and are usually described as distinct ranges; topographically, however, they seem to form a continuation of the ranges running southward from the Santa Victoria and forming the eastern rampart of the great central plateau of which the Puna de Atacama covers a large part.
During the last months of President Uriburu's administration, matters had reached a climax, especially in connexion with the delimitation in a district known as the Puna de Atacama.
The question of the Puna de Atacama was referred to a tribunal composed of the United States minister to Argentina and of one Argentine and one Chilean delegate; that of the southern frontier in Patagonia to the British crown.
The region of the Cordilleras of the Andes is divided into Puna, or lofty uninhabited wilderness, and sierra, or inhabitable moun- Sierra.
