Hidden hall of records behind Lincoln's face on Mount Rushmore!

Pictures have emerged of a hidden "hall of records" behind Lincoln on Mount Rushmore which contains the history of the USA. It tells the story of the USA for future generations and contains many of America's charter documents. Pictures can be found online. I read the story on dailymail. Thought it was very cool considering rooms such as this are thought to have been left by advanced civilizations of the past. Anyways though it was a cool bit of info I had never heard of. Check it out, It would be awesome to see what they have actually stored up there in the vault!
