In this survey of the evidence for the yeti's existence and likely identity, the authors point out that the misleadingly named ‘abominable snowman’ is not a creature of the snows at all, but should be looked for in the dense Himalayan forests, which could support it. At present the authors are engaged in studying one such forest area, the Arun Valley between Everest and Kanchenjunga, on behalf of the Thailand Association for the Conservation of Wildlife. In January this year they reported having had ‘three incidents involving yeti so far, but only one yielded solid evidence’. On December 18 Cronin's and Emery's tent on a ridge in the upper Arun ‘was visited by an animal which left tracks that are not referable to any known animal’—see the photograph by Jeflrey McNeely on the next page.
