Manga
The Manga plain stretches west of Lake Chad, its sandy surface broken by dunes and shallow depressions. To the north the plain gives way to drier pastoral country, while farther south the depressions support cultivation. From Boutti an old caravan route led north through Kossotori and Agadem toward Bilma; N'Guigmi, nearer the lake, was also connected with the salt trade of the Kawar oases.
