In the far eastern fringes of the Himalayas, a mighty river is born, high in the remote wilderness of Tibet. Known there as the Yarlung Tsangpo, this river flows eastward, carving through mountain ranges, whispering secrets of ancient glaciers. But just as it reaches a mystical curve, the Great Bend near Namcha Barwa, it performs a breathtaking spin and turns south, descending into the plains of Arunachal Pradesh, where it is welcomed with a new name ...The Brahmaputra.
