Gran Chaco

The Gran Chaco ('Gran' from Spanish, meaning 'large', and 'Chaco' from Quechua, meaning 'hunting land') is a South American geographical region shared between Argentina, Bolivia, Brazil, and Paraguay. It is a hot and dry lowland region belonging to the Río de la Plata river basin. From 1932-1935, Paraguay and Bolivia fought over supposed oil reserves in a portion of the Gran Chaco; oil was never found in that area.
