The territory of the province of Buenos Aires is part of the pampas. The sandy soil prevails in the western region which is the highest. The eastern region has depressed areas while the fringe of the Parana river, which then becomes Rio de La Plata, is a wavy plain. The mountain systems of Tandilia and Ventania are in the south, with northwest-southeast direction.

System of Tandilia

The System of Tandilia is conformed by hills and slopes which cover an extension of 300 Km, from the mountains of Quillalauquén in the center of the province up to Cabo Corrientes on the Atlantic ocean. Next to the Escudo Canádico in Canada and the Baltic Shield in Finland and Sweden, they constitute the oldest systems in the planet. The relief of the mountains of Tandilia has been shaped according to the different rock costitution. The form of domes corresponds to the granitic rock, plateaus to metamorphic and conical rocks with base of resistant rocks. The mountains which are part of the system are:

  • Sierra of Olavarría: integrated by Quillalauquén, of the China, Dos Hermanas and Bayas, this last one is the most elevated, reaching the 315 meters high.

  • Sierra of Azul and Tandil: rounded, integrated by those of Tandil. The hill which stands out is Albión 502 meters high.

  • Sierra of Balcarce: they are to the east of Tandil. The system is constituted by the hills Bachicha, Chata and Vulcán. They extend toward the south, by those of Vigilancia, Los Padres and La Peregrina.

  • Sierra of La Tinta: to the south of Tandil, is separated by a depression of Tectonic origin. The system goes on up to the mountains of Necochea with south direction to: La Tinta, Barker and Juanita which are in the group of La Tinta.
System of Ventania
The System of Ventania is formed by hills guided toward northwest-southeast. There are two sections, the Westerner which includes the mountains of Puán, Cura Malal, Bravard and La Ventana. Traverse valleys separate the mountain ranges. The hill Tres Picos with 1247 meters is the highest in the system. The eastern section is constituted by the mountains of Tunas and Pillahuincó. The maximum height corresponds to the hill La Tigra which reaches 730 meters high, located in the mountain of The Tunas.
The most important rivers in the region are the river Areco and the river Luján which drain in the Paraná and the rivers Las Conchas, Matanza, Riachuelo, Samborombón and Salado which drain into the Rio de La Plata. The Salado river is born in the south of the province of Santa Fe, travels along La Pampa and finally drains in the bay of Samborombóm. It is 700 Km long and its tributaries flow from the mountains of Tandilia. To the south of the province, there are streams and rivers of the System of Tandilia and Ventania which drain into the Atlantic or into coast lagoons. The rivers and derived streams of the system of Tandilia flow to the bay of Samborombón or the lagoon Mar Chiquita, and then, to the Atlantic ocean. The Chilcas, Napaleofú and Grande belong to this group. Those that go directly to the ocean are the river Quequén Grande, Claromecó, Quequén Salado and the Cristiano Muerto stream. The Sauce Grande river, the Napostá Grande stream and the Sauce Chico river derive from the system of Ventania and drain into the ocean. The riversides of the province of Buenos Aires are low, with bays and inlets, originated by blooming of the rocks. The city of Buenos Aires, La Plata, the ports of San Fernando, Olivos and Ensenada are located on the riversides. Among the most remarkable accidents are Punta Quilmes, Punta Colorada, Punta Lara, Punta Indio, Punta Piedras and Punta Norte of the Cabo San Antonio. The Atlantic coast covers the territory that extends from Punta Norte up to Punta Sur of Cabo San Antonio, then toward the south up to the system of Tandilia. In Punta Mogotes to the south of the city of Mar del Plata, the coast bends towards the southwest, forming an arch which finishes in Bahía Blanca. Among the main geographical accidents of the coast stand out the Barranca, Quequén, Necochea, Monte Hermoso, and the Puntas Negra, Desnudez, Asunción and Sauce. In Bahía Blanca the islands of Trinidad, of del Palo, Bermeja and the peninsula Verde are. To the south of the bay of the Río Colorado, the Anegada Bay, the Islands of the Riachos, Flamenco, Gama, Jabali and San Blas's Bay .
