Carcarañá River

It begins at the confluence of the Río Tercero and the Saladillo River (the lower course of the Río Cuarto) in the south-east of the province of Córdoba (near Cruz Alta, at 33°01′S 61°48′W / 33.017°S 61.800°W / -33.017; -61.800) and flows eastward into the province of Santa Fe, which it crosses.

In Santa Fe the river first turns south, then east and finally north-east, passing by the city of Carcarañá.

It receives the waters of the Cañada de Gómez (near the city of the same name, at 32°51′S 61°9′W / 32.850°S 61.150°W / -32.850; -61.150), develops cascades and becomes constrained within ravines up to 20 metres (66 ft) high.

The mouth of the Carcarañá River was the location of the first European settlement in the Río de la Plata region and present-day Argentina.

In 1527 Sebastian Cabot, a Venetian at the service of Spain, established the Sancti Spiritus Fort there.
