Dibang
The Dibang descends from the snowy eastern Himalaya through steep gorges and the Mishmi Hills before entering the Brahmaputra plain near Sadiya. Its tributaries include the Dri and the Mathun, which drain the mountain valleys above. The valley is home to the Idu Mishmi, whose traditions associate the rivers and mountains with a sacred landscape. In the lower country, remains at Chidu and Chimri bear witness to old settlements near the edge of the plains.
