Overview of the Episode

In this episode marking Mount Rushmore’s 100th anniversary, Sachet Pfeiffer interviews author Matthew Davis about his new book chronicling the story behind the American landmark. The conversation covers the monument’s origins, the changes in its vision, questions of its completeness, and the ongoing controversy around its location on sacred Lakota land.

Key Discussion Points & Insights

1. Origin and Purpose of Mount Rushmore

• Economic Motivation: The original idea for Mount Rushmore was proposed by South Dakota state historian Doane Robinson in the 1920s, amid a state economic crisis after World War I.

  • “The initial idea for Mount Rushmore came from a state historian named Doane Robinson, who was very concerned about the state's economy in the 1920s. ... So he landed on this idea of tourism… for a tourist attraction.” (Matthew Davis, 01:55)

• Original Vision: Robinson imagined figures from the American West—Lakota leader Red Cloud, Sacagawea, Lewis and Clark, and Custer—sculpted into the Black Hills' natural pinnacles.

2. How the Vision Changed

• Shift to U.S. Presidents: The vision changed when sculptor Gutzon Borglum was hired.
  • “Gunson Borglum wanted to create a memorial to American empire, to American exceptionalism. And he had the idea of carving four presidents into Mount Rushmore… George Washington, Thomas Jefferson, Abraham Lincoln, and Theodore Roosevelt.” (Matthew Davis, 03:02)

3. Challenges in Construction and Incompleteness

• Duration and Obstacles:

  • Construction took from 1927 to 1941 due to:
    • Funding issues
    • Seasonal work (winters in South Dakota were too cold)
    • Lack of modern technology (no laser scanning, minimal environmental studies)
  • “You can only work in the summer months… There was no technological laser scanning… There are very little environmental reports put forward beforehand about how the memorial should be carved.” (Matthew Davis, 03:39)

• Not Fully Complete:

  • Borglum’s original vision included the presidents’ torsos, not just their faces. This was abandoned because of funding shortfalls.
  • “Borglum's original vision was to include the torsos of the presidents, not just the faces. And that, of course, is not the case at Mount Rushmore.” (Matthew Davis, 04:19)

• Visible Rubble:

  • Granite boulders (dynamite rubble) at the base remain as planned removal was never funded.
  • “You'll see rubble at the bottom of the faces … those were initially going to be removed, but the memorial ran out of money… they could not remove those.” (Matthew Davis, 04:32)

4. Lakota Land and Legal Controversy

• Stolen Sacred Land:

  • The site is on sacred Lakota land, taken by the United States. The Supreme Court mandated the U.S. pay $100 million for the seizure, but the Lakota refuse the money, wanting the land back instead.
  • “The Lakota continued to refuse to take that money because they say they just want land back.” (Sachet Pfeiffer, 04:42)

• Likelihood of Return:

  • Davis is skeptical about the U.S. ever returning the land to the Lakota, though there is discussion of co-stewardship.
  • “I don't think it's that likely to happen … that doesn't mean that many Lakota people don't want the land back. There is a big rallying cry … as it was taken illegally, as the Supreme Court said.” (Matthew Davis, 05:05)

5. Personal Experience and Tourism Today

• Favorite Season to Visit:

  • Davis recommends visiting in the fall for the best weather and views, fewer crowds, and historical resonance.
  • “I love the Black Hills in October ... The crowds are not as many as they are in summertime. It's a perfect time of year.” (Matthew Davis, 06:06)

• Tourist Impact:

  • The monument has more than achieved its original purpose as a tourist draw:
    • Over 2 million annual visitors
    • Major economic impact for the region
    • Visitors often explore nearby towns and parks as well
  • “If [Doane Robinson] were alive today and recognized and understood that over 2 million people visit Mount Rushmore every year, he would have been overjoyed with that result.” (Matthew Davis, 06:40)
