Location of Atlantis...This Week
From BBConline: "Satellite photos of southern Spain reveal features on the ground appearing to match descriptions made by Greek scholar Plato of the fabled utopia. Dr Rainer Kühne thinks the 'island' of Atlantis simply referred to a region of the southern Spanish coast destroyed by a flood between 800 BC and 500 BC."
He lays out his theory pretty well and it is like anything else about Atlantis or any other fabled civilization or secret of the universe: there is room for interpretation. Though Kühne work the evidence pretty hard. Kühne's CV lists this article -- 15. R. W. Kühne, Location and Dating of Atlantis, Antiquity, 78, 300 (2004) -- and gives a URL to Antiquity magazine that doesn't work. Issue 300 appears to be the summer issue and it hasn't shown up online yet.
