Yeti evidence too hard!

In SF#51, we printed a news item about photographs taken in the Himalayas by A.B. Wooldridge that were thought to show a Yeti. The latest issue of Cryptozoology contains a letter from Wooldridge in which he tells of his return, in 1987, to the site where the 1986 photos were taken. The bush in the 1986 photos was still there; the Yeti wasn't; the snow was somewhat deeper. Wooldridge and some companions took more pictures of the site:

"Stereo pairs of photos taken in 1987 have been used to produce a threedimensional map of the terrain near the bush. When this is used to derive an absolute scale for pairs of photos from 1986, it shows that, whatever I photographed in 1986, lies below the snow level in the 1987 photos. The object is leaning slightly uphill, and no movement can be detected when comparing photos taken at different times in 1986. The apparent change in position relative to the bush in some photos taken from different camera positions is caused by parallax. This evidence demonstrates beyond a reasonable doubt that, what I had believed to be a stationary, living creature was, in reality, a rock."

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
