"Little explored and virtually inaccessible, the Tsangpo Gorge in South-east Tibet is the world's deepest gorge. Through it twists the Yarlong Tsangpo, Tibet's great river, emerging far below on the plains of India. This is the story of its exploration and an account of the rich plant and animal life found there." "Riddle of the Tsangpo Gorges is the account of plant-hunter and explorer Frank Kingdon Ward's most important expedition. First published in 1926, it has been long out of print. Kenneth Cox, Kenneth Storm, Jr. and Ian Baker have spent the last ten years retracing the route of the 1924-25 expedition and have managed to reach further into this magical and only partly explored land.". "This new edition contains the original Kingdon Ward text (with about fifty of his own photographs from the archive at the Royal Geographical Society) and extensive additional material including a new Foreword by Kingdon Ward's widow, Jean Rasmussen, a brief biography of Kingdon Ward, a history of the exploration and geography of the region, an account of the religious significance of the area as a a place of pilgrimage, a note on the geology and more than 250 colour photographs with detailed captions on the plants of the area, most of which are described by Kingdon Ward in the original text." "There are first person accounts of recent expeditions to the area by Ken Cox and Ken Storm, Jr. and a photographic essay documents for the first time in a book the 'new' Hidden Falls located in the portion of the gorge left unexplored by Frank Kingdon Ward and Lord Cawdor in 1924."--BOOK JACKET.
