Hulu Mesuji
The upper Mesuji lies in the forested lowlands of southern Sumatra, north of the Tulang Bawang river system. Its streams flow east towards the coastal plain and the Java Sea. The rivers of this country cross wet ground and low hills, linking inland settlements with the broad estuaries of the east coast. Farther south, the Tulang Bawang served as a route for the pepper trade between Lampung and the maritime world across the Sunda Strait.
