When you gaze up at the towering faces of Washington, Jefferson, Roosevelt, and Lincoln carved into Mount Rushmore’s granite mountainside, you’re only seeing part of the story. Hidden behind Lincoln’s head is a 70-foot-long chamber that remains concealed from view behind the mighty brow. Most visitors walking the Presidential Trail have no idea that this secret room even exists. It’s called the Hall of Records, and its creation was perhaps the most ambitious part of sculptor Gutzon Borglum’s entire vision for the monument.
The Sculptor’s Grand Vision That Congress Didn’t Want
The Hall of Records was conceived by Mount Rushmore sculptor Gutzon Borglum even before he began work on the monument in 1927, with his original vision for the memorial including an inscription carved next to the presidents that would describe nine important events in U.S. history occurring between 1776 and 1906, but the idea proved problematic in practice. Borglum envisioned a grand hall measuring 80 feet tall by 100 feet long, accessible via an 800-foot granite staircase, that would include busts of famous Americans, as well as bronze and glass cabinets containing priceless historical documents like the U.S. Constitution and Declaration of Independence, with a massive bronze eagle with a 38-foot wingspread mounted above the entrance. The thing is, Borglum worried that Mount Rushmore might one day become as mysterious to future civilizations as Stonehenge is to us today. He feared people thousands of years from now would look at these giant faces and have absolutely no context for what they meant or why they existed.
When Dynamite Met Congressional Reality
Work on the Hall of Records began in July 1938. Workers blasted a 70-foot-long cavern using dynamite, though the government was wary of the ambitious project and insisted that Borglum finish the heads before he continued working on the Hall of Records. Borglum died unexpectedly in 1941, and though his son put the finishing touches on the sculptural portraits, the Hall of Records project was abandoned. Here’s the thing about government funding. Congress essentially told Borglum to focus on the faces first, saying the Hall could wait. A year into the construction, the federal government, which covered nearly all the cost of constructing the monument, tightened its purse strings and ordered Borglum to stop work on the Hall of Records and focus his full efforts on completing the presidential profiles. The sculptor’s death in March 1941, followed by America’s entry into World War II, sealed the fate of his grand chamber. What remained was essentially an unfinished tunnel with rough, jagged walls and visible dynamite holes.
Carved into the solid granite wall of a small canyon just behind the presidential lineup is an 18-foot-tall doorway that resembles the entrance to an ancient tomb, with anyone crossing the threshold discovering an empty room approximately 75 feet long with a 35-foot-tall ceiling. You can still see the dynamite channels inside the Hall of Records. The walls are rough and unfinished, bearing red numbers that some believe were painted by Borglum himself as guides for workers removing rock. It’s honestly a stark contrast to the smooth, detailed faces outside. The chamber narrows as it penetrates deeper into the mountain, ending abruptly where construction simply stopped. No bronze eagle, no glass cabinets, no grand staircase. Just raw granite and the echoes of an abandoned dream.
The 1998 Completion That Changed Everything
For nearly six decades, the Hall sat empty and largely forgotten. Then on August 9, 1998, four generations of Borglum’s family gathered in the incomplete chamber as 16 porcelain enamel panels were added to the site, inscribed with the words of documents such as the Declaration of Independence, biographies of the sculptor and his presidential subjects and histories of the memorial’s construction and the United States, placed inside a teakwood box and titanium vault and lowered into the ground, then covered by a 1,200-pound black granite capstone. The granite slab is carved with a quote from Borglum’s original plans: “…let us place there, carved high, as close to heaven as we can, the words of our leaders, their faces, to show posterity what manner of men they were. Then breathe a prayer that these records will endure until the wind and rain alone shall wear them away.” Borglum’s daughter Mary Ellis attended the ceremony and declared it the completion of her father’s vision, even if not in the form he’d imagined.
What’s Actually Sealed Inside the Vault
Sixteen panels detailing the carving of Mount Rushmore, the reason why each president was chosen, a biography of Borglum, and the words to the Bill of Rights, U.S. Constitution, and Declaration of Independence were placed inside a wooden box, with this repository of records then sealed inside a titanium vault, placed inside the tunnel, and protected by a 1,200-pound slab of granite. These aren’t the original documents, of course. They’re porcelain enamel panels chosen specifically for their durability. This is not a time capsule, as these documents are to remain buried for thousands of years, with Borglum literally having it in mind to send the message of our country to future civilizations. It’s designed to outlast us all, a message in a bottle for whatever comes after
There’s something deeply moving about Borglum’s intention here. Borglum wrote, “Each succeeding civilization forgets its predecessor. Civilizations are ghouls,” and to make sure he was never forgotten, Borglum began work on a hidden room, with construction on Mount Rushmore beginning in 1927 and Borglum beginning his massive “Hall of Records” in 1938. The room was envisioned as part time capsule, part defense against humanity’s inevitable doom, and part message to visitors from the stars or post-apocalyptic survivors: We were here, we were America, and this is what we were all about. It’s a sobering thought. Borglum understood that everything fades, that memory itself is fragile. He wanted to leave something permanent, something that would speak across millennia. Whether his vision succeeds remains to be seen, but the attempt itself speaks volumes about human ambition and our desperate need to be remembered. What do you think about this hidden time capsule? Does knowing it exists change how you see Mount Rushmore?
