Niger River and Lake Manantali, Mali and Guinea13.1N 10.3W
Sun glint highlights the Niger River as it runs from Guinea (below) into Mali (above). In addition to the glint, sediment give the river a light tan color.
The Niger River’s source is in the Guinea Highlands in southeastern Guinea. It runs in a crescent through Mali, Niger, on the border with Benin and then through Nigeria. It is the third-longest river in Africa, extending about 4,180 km (2,600 mi).
Also visible in the top left corner is Lake Manantali, a large artificial lake, formed by the 1989 construction of the Manantali Dam, on the Bafing River in Mali. Its northern point is located 90 km to the south-east of the city of Bafoulabé.
