Image Caption: NM23-719-448 Rio Parana, Argentina Winter/Spring 1997
The Rio Parana forms a broad, swampy floodplain (dark swath) in northeastern Argentina, which extends from Corrientes (north, near the Paraguayan border) to the western end of the Rio de la Plata estuary. This section of the floodplain is midway between Rosario and Buenos Aires. The main channel of the river (winding, light-colored band at center of image) flows southeastward along a bluff or escarpment, known as the Barranca (100 to 150 feet/ 30 to 45 meters high). Within the floodplain is a secondary channel, as well as old meander scars and shifting sandbars that are typical of a braided river. Extensive agricultural fields (rectilinear pattern) are observed southwest of the Rio Parana. This is part of the Pampas region of Argentina, noted for sheep and cattle ranching, as well as for cultivation of corn (maize), wheat, and alfalfa. (Refer to NM23-719-442, NM23-719-444, and NM23-719-446 for other images of the Rio Parana in northeast Argentina).
