Cap Vert Between Senegal and Gambia Rivers, Senegal14.7N 17.3W
Visible at the top of this wide-swath ASAR image is the Sénégal River, a 1,790 km (1,110 mi) long river in West Africa that forms the border between Senegal and Mauritania. The Sénégal’s headwaters are the Semefé (Bakoye) and Bafing rivers which both originate in Guinea. Later in its course, the Senegal River flows through semi-arid land in the north of Senegal, forming the border with Mauritania, and into the Atlantic. It is separated from the Atlantic Ocean by a thin strip of sand called the Langue de Barbarie before it pours into the ocean itself.
Visible near the bottom edge is the Gambia River, which runs 1,130 kilometres (700 mi) from the Fouta Djallon plateau in north Guinea westward through Senegal and The Gambia to the Atlantic Ocean at the city of Banjul. About 100 km from its mouth it gradually widens to over 10 km wide where it meets the sea.
Protruding off the coast between the two rivers is Cap-Vert, a peninsula in Senegal, and the westernmost point of the continent of Africa and of the Old World mainland. Cap-Vert is a rocky promontory extending west from the main sandy areas of Senegal. Dakar, the capital of Senegal, is located near the southern tip. Twin volcanic cones, the Deux Mamelles (“Two Teats”), dominate the landscape along the coast northwest of Dakar.
