Orange Sediments in Antongil Bay, Madagascar
Helodranon’ Antongila (Bay of Antongila), more commonly called Antongil Bay in English, is the largest bay in Madagascar.
It is at the northern end of the east coast of the island and for administrative purposes it is within the autonomous province of Toamasina.
The bay is about 60 km long and 30 km wide, and is formed by the Masoala peninsula on its eastern side. At the northern end of the bay is the island of Nosy Mangabe and the town of Maroantsetra.
Several rivers run through the rainforest surrounding this area before discharging orange, brown and yellow sediments into the bay.
