Monk's Mound

Monk's Mound. You know how people treat the very existence of the Great Pyramid in Egypt as one of history's most confounding mysteries?

Well, Cahokia's pyramid dwarfs that one, both in size and in degree of difficulty. The mound contains more than 2.16 billion pounds of soil, some of which had to be carried from hundreds of miles away, to make sure the city's giant monument was vividly colored. To put that in perspective, all 13 million people who live in the state of Illinois today would have to carry three 50-pound baskets of soil from as far away as Indiana to construct another one.

"What if we built a middle finger large enough to flip off God?"

So why does Egypt get millions of dollars of tourism and Time Life documentaries dedicated to their boring old sand pyramids, while you didn't even know about the giant blue, red, white, black, gray, brown and orange testament to engineering and human willpower just outside of St. Louis? Well, because the Egyptians know how to treat one of the Eight Wonders of the World.

America, on the other hand, appears to be trying to figure out how to turn it into a parking lot.
