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 from below on the plains of India. This is the story of its exploration and the rich plant and animal life found there. Riddle of the Tsangpo Gorges , first published in 1926, is the fascinating account of plant-hunter and explorer Frank Kingdon Ward’s most important expedition. Kenneth Cox, Kenneth Storm, Jr. and Ian Baker spent over ten years retracing the route of the 1924-25 expedition and managed to reach further into this magical and only partly explored land. The book contains the original Kingdon Ward text and extensive additional material, including a history of the exploration, geography and religious significance of the area 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 expeditions to the area by Kenneth Cox and Kenneth 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.
