Argentina is divided into twenty-three provinces and one
Autonomous City. Buenos Aires Province is divided into 134 partidos, while the
remaining Provinces are divided into 376 departments. Departments and Partidos
are further subdivided into municipalities or districts. With the exception of
Buenos Aires Province, the nation's provinces have chosen in recent years to
enter into treaties with other provinces, forming four federated regions aimed
at fostering economic integration and development: Center Region, Patagonic
Region, New Cuyo Region, and the Argentine Greater North Region.
Mendoza province at Cerro Aconcagua. The lowest point is Laguna del Carbón in
Santa Cruz province, −105 m below sea level. The major rivers are the Paraná,
the Pilcomayo, Paraguay, Bermejo, Colorado, Río Negro, Salado and the Uruguay.
There are several large lakes including Argentino and Viedma in Santa Cruz,
Nahuel Huapi between Río Negro and Neuquén, Fagnano in Tierra del Fuego, and
Colhué Huapi and Musters in Chubut. Lake Buenos Aires and O'Higgins/San Martín
Lake are shared with Chile. Mar Chiquita, Córdoba, is the largest salt water
lake in the country. There are numerous reservoirs created by dams. The 4,665
km long Atlantic coast has been a popular local vacation area for over a
century, and varies between areas of sand dunes and cliffs. The continental
platform is unusually wide; this shallow area of the Atlantic is called the
Argentine Sea. The waters are rich in fisheries and possibly hold important
hydrocarbon energy resources. The two major ocean currents affecting the coast
are the warm Brazil Current and the cold Falkland 
Current. Because of the
unevenness of the coastal landmass, the two currents alternate in their
influence on climate and do not allow temperatures to fall evenly with higher
latitude. The southern coast of Tierra del Fuego forms the north shore of the
Drake Passage.
