For some, Mount Rushmore might appear like the perfect place to hide amazing mysteries. This idea, in fact, clearly wasn’t lost on Hollywood, as demonstrated by the golden city discovered under the mountain in 2007 movie National Treasure: Book of Secrets. But in reality, Rushmore really does holds a real secret, after all.
Mount Rushmore is one of the United States’ most iconic monuments, right up there with the Statue of Liberty. As if you didn’t know, the landform is shaped into 60-foot-tall faces of some of the nation’s supposedly greatest presidents. These are Theodore Roosevelt, George Washington, Abraham Lincoln and Thomas Jefferson.
