Monks Mound in Illinois is the largest-known prehistoric earthwork in the Western Hemisphere. Built by the Mississippian people, it's a stunning site, but its purpose is largely unknown.
It's given us American icons as notorious as Al Capone and as heroic as Abraham Lincoln. It's where endless rows of corn blanket the fields and towering buildings touch the sky. The state of Illinois is full of awe-inspiring sights and captivating drama, and this aerial excursion explores it all. From the Great Fire of Chicago to the Great Migration that brought Muddy Waters and the blues up north, we visit the places and people that tell Illinois' powerful story.
