Mount Rushmore Facts

Mount Rushmore has a secret: a 70-foot granite tunnel cut directly behind the faces. Sculptor Gutzon Borglum began drilling it in 1938 to house America's founding documents for future civilizations. Congress shut the project down in 1939 and Borglum died in 1941. In 1998, his family lowered 16 porcelain panels into a titanium vault and sealed it under a 1,200-pound granite capstone. Nobody can go inside.

Luigi Del Bianco immigrated from Italy as a teenager, already trained as a stone carver. Sculptor Gutzon Borglum named him Chief Carver of Mount Rushmore in 1935. He was the one man trusted to finish all four presidents' faces. Del Bianco carved the twinkle in Lincoln's eyes and shaped Jefferson's lips. Borglum called him worth any three men in America. An Italian immigrant gave the presidents their faces.
