Beautiful Mount Rushmore
Mount Rushmore is well-known for the sculptures of the heads of former United States presidents, but there is something else there that you might not be aware of. The Hall of Records is a secret room that can be found in the Black Hills of Keystone. It can be accessed by going behind the head of Abraham Lincoln.
The sculptor Gutzon Borglum created this room with the intention that it would be used to store one of the most significant historical documents and artifacts in the annals of the history of the United States of America. This is a completely unique piece of artwork, and it deserves our applause.
