A Hole in Lincoln’s Head
If someone told you there was a hidden chamber in the back of Lincoln’s head on Mt. Rushmore, you would probably expect you’re dealing with a crazy conspiracy theorist. However, the reality is that there is some sort of chamber in the mountain that the original artist created.

True conspiracies come into being when people consider what the purpose of that chamber is. While no one knows for sure, many are under the impression that the chamber was created to house the nation’s most prized possessions. However, there are probably much more secure locations for such items.
