Portuguese sailors in the late 1400s noticed something unusual where this West African river emptied into the Gulf of Guinea: schools of cavalla, the horse mackerel, churning the brackish water at its mouth. They named the river for the fish, and the name stuck through centuries of trade, colonization, and independence. Today the Cavalla stretches 515 kilometers from its headwaters near Mont Nimba in Guinea to the sea, making it the longest river in Liberia and one of the most important waterways in the region. For roughly two-thirds of that distance, it does double duty as the international boundary between Liberia and Ivory Coast -- a border drawn not by diplomats with rulers but by the river itself, carving its slow, persistent line through the West African lowlands.
