4. Mount Rushmore’s Hidden Vault
Behind the grandeur of Mount Rushmore’s colossal stone faces lies a secret vault embedded within the monument. Architect Gutzon Borglum, the visionary behind this iconic carving, had a vision that extended beyond the surface. While he passed away before its completion, his dream of a hidden chamber came to fruition in the 1990s.
This titanium vault safeguards significant historical artifacts, including the Declaration of Independence, the Bill of Rights, and a biography of Borglum himself. Regrettably, the vault remains off-limits to the public due to preservation and security concerns, leaving visitors to wonder about the treasures held within its impenetrable confines.
