  • Summary

  • The Coso Artifact - a man-made, cylindrical object apparently encased in a geode - was discovered by Wallace Lane, Virginia Maxey and Mike Mikesell while prospecting for gems in Olancha, California on February 13th, 1961. The OOPArt (or ‘out-of-place artifact’) caused a sensation amongst Creationists, Forteans and conspiracists, who believed it might be up to half a million years old - but has since been identified as a 1920s-era Champion spark plug. In this episode, Arion, Rebecca and Olly consider whether the ‘Rock Hounds’ were deliberately defrauding people, or were just open-minded enthusiasts; ask why their find had such resonance with Creationists, when its existence cannot be consistent with the world being merely thousands of years old; and reveal how the ‘mystery’ was conclusively debunked… Further Reading: • ‘When Some 1920s Garbage Was Mistaken for an Ancient Artifact’ (Smithsonian Magazine, 2017): https://www.smithsonianmag.com/smart-news/1920s-garbage-or-ancient-artifact-probably-1920s-garbage-180962081/ • ‘Hidden History - Lost Civilizations, Secret Knowledge, and Ancient Mysteries, By Brian Haughton’ (Red Wheel/Weiser, 2007): https://www.google.co.uk/books/edition/Hidden_History/295EDwAAQBAJ?hl=en&gbpv=1&dq=coso+artifact&pg=PT173&printsec=frontcover • ‘Coso Artifact: Science Triumphs Over Theorists’ (Science For Everyone, 2022): https://www.youtube.com/watch?v=GawHMQpIGrU Love the show?
