Senegal and Geba Rivers on West Africa Coast14.7N 17.3W
The landscape of West Africa gradually changes from the arid Sahara Desert in Mauritania in the north to greener, more vegetated land in Guinea-Bissau and Guinea. Situated in the tan and brown area of vegetation change are Senegal and the Gambia.
Two rivers can be seen reaching the coast: the Senegal River, to the north, on the border between Mauritania and Senegal, and the Geba River in Guinea-Bissau. Tan sediments can be seen spilling from the latter into the Atlantic Ocean.
