Again on the track of the controversial (The Rivers Ran East (1953) was in search of the legendary seven cities of Cibola) veteran explorer Clark's journal here follows the precarious trip from Hong Kong to the inner reaches of forbidden Tibet in search of the mysterious God-mountain range, the Amne Machen, allegedly higher than Everest. His first reports on this five months trek were greeted with incredulity by the press of this country; Life, October, 1949, openly doubted his claims that the Amne Machen peak, seen and estimated from a distance, was 28,000 feet high - -or higher than Everest. This book, which Clark did not intend to write, is an answer to some of the hostile ""legends"" which have grown up around the 1949 trip and admits that the measurements of the peak were made with outmoded instruments that could be wrong by as much as 2,500 feet -- one way or the other. Regardless of the argument about the peak, this is still an exciting account from its financing by Governor Ma Pu-fang to the time when they viewed the long-sought mountain range. Hunger, hostile tribesmen and a ""mauling"" wind often threatened to force the explorers to turn back and there were times when their goal seemed impossible of achievement. But they did get through, saw the mountain range, collected their specimens and data for use when development of the resources of this wasteland is called for and came home -- to disbelief. Much of the temper of the tribes who inhabit Tibet, ""citadel of isolation"" is revealed; the reporting is straightforward and credible; it's a frank, lively answer to a stay-at-home's wanderlust.
