Burundi - Gasumo, the southernmost source of the Nile

6 671 km long, the Nile River crosses 6 African countries: Burundi, Rwanda, Uganda, Tanzania, Sudan and Egypt. It is the longest river in Africa. Its source remained unknown for a long time. From the point of view of history, Ptolemy, a Greek geographer of the 2nd century, thought that this spring was in great snowy mountains near the equator and that the snow melting fed the lakes located further north, where two streams came out of which the meeting formed the Nile. Until the 15th century, knowledge did not progress and the hypothesis of Ptolemy was maintained.
