In search of the source of the Mekong River, explorer-anthropologist Michel Peissel and his team travel across Tibet's highest plateau to the roof of the world. It is a region that over the centuries has killed more than a dozen explorers. Here at 16,000 feet, they encounter wolves, snow leopards, and the fiercely independent Khamba tribesmen - mounted nomads that have guarded the location of the source of Asia's third largest river. Beset by hail storms and the loss of three horses to the wolves, the expedition comes upon two tiny bubbling springs in the heart of China's wild west on the 16,300 foot Ruspa pass, the birthplace of the mighty Mekong. It is a true adventure set in the mountainous kingdom of Nangchen deep in mysterious Tibet.
