The original design for Mount Rushmore depicted the four presidents from the waist up!

It's pretty difficult to deem Gutzon Borglum's initial vision for his colossal sculpture very feasible, considering it took over 14 years and nearly a million dollars just to carve out the presidents' faces! Regardless, a lack of funding forced the project to be scaled back to include only the heads of the former heads of state. This is probably a good thing though, because this preliminary design would have called for a sculpture well over 200 feet high. Oh, and if you're worried about the potential deterioration of this beloved national landmark, fear not - its estimated erosion rate is one inch every 1,000 years, so this mountain isn't due to be 'defaced' anytime soon!
