Episode notes
Tourism As The Origin
- Mount Rushmore began as an economic idea to boost South Dakota tourism after WWI.
- Doan Robinson proposed carving regional Western figures to attract car travelers to the Black Hills.
Borglum Recast The Purpose
- Sculptor Gutzon Borglum reframed the project as a monument to American empire and exceptionalism.
- He selected four presidents to symbolize different aspects of that national narrative.
A Long, Seasonal Carving
- The carving took from 1927 to 1941 because funding, seasonal work, and manual techniques slowed progress.
- Borglum relied on faith and iterative on-site decisions without modern scanning or environmental reports.
