Barito is an 909 km long river, located in South Kalimantan, Indonesia. It originates in the Muller Mountain Range from where it flows southward into the Java Sea. Its main affluent is the Martapura River and it passes through the city of Banjarmasin.
This river is the location of the closest language to Malagasy language in Africa, belonging to the Ma'anyan language of Dayaks, from where settlers arrived in Madagascar (presumably in waves) from the 3rd to 10th century AD and from which the current island nation's population largely traces its origins.
