October 4
Carving Begins on Mount Rushmore Sculpture
Sculptor Gutzon Borglum launched the physical work of carving four presidential faces into a South Dakota mountain on October 4, 1927, after years of planning and a formal dedication two months earlier.
Summary
Sculptor Gutzon Borglum had long envisioned a massive monument in South Dakota's Black Hills to celebrate American presidents and attract tourism. After years of planning, site selection, and a dedication ceremony earlier in 1927, actual carving commenced on October 4. Workers used dynamite for the bulk of material removal on the granite face, followed by precise drilling and hand-finishing techniques. The project, funded through a mix of private and eventual federal support, aimed to depict George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. Over the next 14 years, approximately 400 workers transformed the mountain despite challenging conditions and funding challenges.
Context
The concept for a monumental sculpture in the Black Hills originated with South Dakota historian Doane Robinson, who in the early 1920s sought a project that would draw tourists to the region while commemorating American history. Robinson enlisted sculptor Gutzon Borglum, already known for large-scale works, who refined the vision into a tribute to four presidents chosen to represent key eras of national growth: George Washington for founding, Thomas Jefferson for expansion, Abraham Lincoln for preservation, and Theodore Roosevelt for development.
What Happened
Borglum selected Mount Rushmore for its exposed granite face and southeastern exposure, which offered suitable light and durability. After site surveys, model-making, and congressional approval for federal involvement, President Calvin Coolidge participated in a dedication ceremony on August 10, 1927, that lent national visibility. Actual carving commenced on October 4 when crews began removing rock from the mountain.
Aftermath
Work proceeded with a workforce that eventually numbered nearly 400, relying on dynamite for the majority of material removal followed by precise drilling and hand tools for finishing. Funding remained precarious through the early years, mixing private donations, state appropriations, and later federal relief support during the Depression.
Legacy
The completed memorial, finished in 1941, stands as one of the most recognized symbols of American presidential leadership and has attracted tens of millions of visitors. Interpretations have evolved to include recognition of its construction on land with deep significance to Indigenous nations and its role as a New Deal-era public works project.
Why It Matters
Mount Rushmore became an iconic symbol of American leadership and expansion, drawing millions of visitors annually and embedding presidential history into the national landscape. It represented a major public works effort during the Great Depression era and remains a defining cultural landmark.
