The Rock Lake Pyramids

Professor James Shertz, of the University of Wisconsin, is trying to get to the bottom of the reputed stone pyramids submerged in Rock Lake, near Lake Mills, Wisconsin. Fishermen have hit the pyramids with their oars when the lake is very low; and others have spotted structures (perhaps as many as four) from the air. In 1937, a diver reported seeing a 29-foot-high pyramid in the murky waters. Recent divers have found boul-der alignments; but the visibility is so poor that organized structures cannot be identified.

Truncated earthen pyramids exist at nearby precolumbian Aztalan; and strange rock piles exist elsewhere in Wisconsin. Consequently, one cannot brush off the idea that some edifices were built at Rock Lake when the water was much lower.

(Smith, Susan Lampert; "Lake Mills' Lost Pyramids," Wisconsin State Journal, June 26, 1983. Cr. R. Heiden via L. Farish.) Comment. The 1937 dives are described in our Handbook Ancient Man. Perhaps it is relevant that sonar-imaging equip-ment has detailed obviously human-built rock structures on the floor of Loch Ness.

Reference. Ancient Man is described here.

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
