As a public service, the mods should probably alert the US Geological Soc. and other countries' similar departments, as to the date the solution to the mystery will be announced. The force of tens of thousands of MR members worldwide smacking themselves in the forehead and screaming "Of course! How could I have been so stupid? I didn't win again!" will probably trigger major global seismic events that could topple their infrastructures! Not to mention shift some tectonic plates!
[Of course to avoid such global calamity, MR could act responsibly and quietly give the prizes to the concerned MR entrant(s) who are actively trying to prevent such a cataclysmic event. Hint. Hint. Just saying.]
