How was Mount Rushmore carved?

Imagine dangling 500 feet in the air from a tiny cable... right in front of a giant stone nose! Welcome to the massive story of Mount Rushmore! In this episode, Mira and Finn travel back to 1927 to find out how four American presidents—George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln—were carved into a mountain in South Dakota. Did you know 90% of the monument was carved using actual dynamite? Boom! Learn how 400 workers blasted away 450,000 tons of rock and dangled from dizzying cliffs to smooth out faces the size of six-story buildings. Amazingly, not a single person died during the 14 years it took to build! We'll also uncover the fascinating secrets behind the monument, from a hidden room meant to hold America's most important documents, to why the mountain is deeply sacred to the Lakota Sioux people, who call it the Six Grandfathers. Grab your hard hat and get ready for an explosive adventure through history!
