Officially the Argentine Republic is a federal republic located in southeastern South America. Sharing the bulk of the Southern Cone with its neighbor Chile, it is bordered by Bolivia and Paraguay to the north; Brazil to the northeast; Uruguay and the South Atlantic Ocean to the east; Chile to the west and the Drake Passage to the south. Second in South America only to Brazil in size and population, Argentina is a plain, rising from the Atlantic to the Chilean border and the towering Andes peaks. Aconcagua (22,834 ft, 6,960 m) is the highest peak in the world outside Asia. Argentina is also bordered by Bolivia and Paraguay on the north, and by Uruguay and Brazil on the east. The northern area is the swampy and partly wooded Gran Chaco, bordering Bolivia and Paraguay. South of that are the rolling, fertile Pampas, which are rich in agriculture and sheep- and cattle-grazing and support most of the population. Further south is Patagonia, a region of cool, arid steppes with some wooded and fertile sections.
