Río Negro

Río Negro is a province of Argentina, located at the northern edge of Patagonia. Neighboring provinces are from the south clockwise Chubut, Neuquén, Mendoza, La Pampa and Buenos Aires. To the east lies the Atlantic Ocean.

Río Negro covers 203,013 km2 (78,383 sq. miles), extending from the Atlantic to the Cordillera of the Andes, to the north of 42°S.

The Río Negro River runs along a wide transverse depression, the middle part of which is followed by the railway which runs to the settlement of Neuquén at the confluence of the rivers Limay and Neuquen. In this depression are several settlements, among them Viedma, the capital of the Río Negro territory, Cipolletti, General Conesa, Choele Choel and General Roca.

To the south of the Río Negro the Patagonian plateau is intersected by the depressions of the Gualicho and Maquinchao, which in former times directed the waters of two great rivers (now disappeared) to the gulf of San Matias, the first-named depression draining the network of the Collon Cura and the second the Nahuel Huapi lake system. In 42°S there is a third broad transverse depression, apparently the bed of another great river, now perished, which carried to the Atlantic the waters of a portion of the eastern slope of the Andes, between 41° and 42°30;S.
