¹¹⁶ It would not be premature to mention an international, collaborative project planned to explore these issues in two of, potentially, the most productive southern Saharan palaeochannels. H. Bocoum of the Institut Fondamental d'Afrique Noire (Dakar) and T. Togola of the Institut des Sciences Humaines (Bamako) (with a Mauritanian co-director) will lead survey and excavation along the Vallée du Golgol (from the Middle Senegal Valley north-east to the Hodh depression) and along the Vallée du Serpent and Fala du Molodo (from the Middle Niger [Méma] north-west to the Hodh). In my opinion, this project is the most exciting archaeological work planned for West Africa in the 1990s.
