The One Trick That Made Mount Rushmore Possible

Mount Rushmore, Mount Rushmore construction, Mount Rushmore history. Four faces. Each as tall as a six-story building. No road reached the top. No power lines reached the site. No safe way for a man to even stand on that cliff, let alone carve it. But none of that was the hardest problem. The hardest problem was smaller than a bathtub: a five-foot plaster model sitting in a studio. Every inch of Washington's nose, every angle of Jefferson's brow, had to be copied from that model onto a cliff twelve times its size - with no computers, no lasers, and less than an inch of room for error. Get the math wrong once, and a president's face is gone forever. The year was 1927, and before anyone could solve that problem, they had to solve a dozen smaller ones first - starting with the fact that no power reached that stretch of the Black Hills at all. The mountain's first power source exploded. Its replacement came from a gold mine that was already going bankrupt. That alone nearly stopped the project - but it wasn't even the strangest problem the crews would face.
