Sofia and Betsiboka Rivers

The central western coast of Madagascar is flanked by an intense, rusty red outflow of sediments. Most are present along the coast of the Melaky region.

Although such red sediments along the coast are typical for Madagascar, due to its red soils and high erosion rates from deforestation further inland, they are usually also seen further north near the mouths of the Sofia River and the Betsiboka River.

Unusually, in this image (see close-up for better detail), those rivers and their respective bays show a lesser presence of sediments. The Sofia River and bay into which it flows (above) are completely lacking in the characteristic red shade. The Betsiboka River is orange, but is not carrying enough red sediments to completely color the Bombetoka Bay (below).
