Strange Blue Pool Found At The Bottom Of Crater Lake

"A mysterious, small aqua-blue pool of dense fluid has been discovered at the bottom of Crater Lake.

"'It is bizarre, it is remarkable,' said Jack Dymond, who with Robert Collier heads the three-year Crater Lake exploration project. 'I have never seen anything like it,' he said.

"The Oregon State University oceanographer said the pool, about 6 feet in depth, is approximately 3 feet wide by 8 feet long. It is near the lush white and orange bacteria mats found last summer."

The murky pool of fluid was discovered during a dive in a research submarine. The temperature of the pool was about 4.5C (40.1F) which made it 1C warmer than the surrounding lake water.

Comment. Some lakes in northern climes still retain ancient seawater in their bottoms. Also, we have the well-publicized African lakes that suddenly overturn, producing clouds of poisonous gases. See our catalog: Anomalies in Geology. Ordering information 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).

  • "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.
