We stopped briefly to admire the fairly wide, meandering Yarlung Tsangpo (Brahmaputra) River. The 2900km-long river rises to the east of Kailash, travels 1700km across Tibet at an average height of 4000m, takes a U-turn at Mount Nancha Barwa, descends rapidly through the Yarlung Tsangpo gorges (the deepest in the world), and then exits at the Bay of Bengal.
