Madagascar is a large island in the Indian Ocean, east of Africa. In the middle of the island lie 3000km mountains from which Betsiboka River runs 525km to form an intricate river delta. On the eastern side of Madagascar stretches rainforest and Mangrove and Savannah on the western side. The Betsiboka River passing through the Mangrove contains reddish iron and aluminum oxides, characteristic silt sediment of the rainforest which pile up at the river delta.

The local scenery on the ground is as follows.
