拉什莫尔山，俗称美国总统山，它看似自然形成，实则是无艺术经验的矿工们用炸药与创新工程打造的奇迹。通过古希腊科技，成功将总统头像完美映射到岩壁上，14年打造出人类史上罕见的工程艺术杰作。
There is something unusual about Mount Rushmore.
Unlike most sculptures which look painstakingly crafted Mount Rushmore almost seems like it formed out of the mountain naturally and not by the work of a great sculptor.
The reality is Mount Rushmore is not only a work of art but an engineering masterpiece.
Despite having zero artistic experience an enormous team of gold miners managed to bring these giant heads into existence using jackhammers, dynamite, and some clever engineering.
We modeled the entire thing to show you how they mapped the design onto the mountain using ancient Greek technology and how all of this was done without losing a single man.
But in order to understand why Mount Rushmore exists in the first place B, we need to go back in time.
In the early 1920s the state of South Dakota was just a few decades old and it was struggling to get its foot in the door.
State historian Doane Robinson saw how tourists from all over the country had been flocking to a new sculpture in the state of Georgia, and this gave him an idea.
He reached out to the sculptor Gutzon Borglum and asked if he'd like to make an enormous sculpture of America's Wild West Heroes.
Borglum was excited by the idea, but thought that more National figures like presidents would draw more attention.
