Puna de Atacama dispute
The Puna de Atacama dispute, sometimes referred to as Puna de Atacama Lawsuit (Spanish: Litigio de la Puna de Atacama), was a border dispute involving Argentina, Chile and Bolivia in the 19th century over the arid high plateau of Puna de Atacama located about 4500 meters above the sea around the current borders of the three countries. The dispute originated with the Chilean annexation of the Bolivian Litoral Department in 1879 during the War of the Pacific.
