Take your own mind-blowing tour at NGS in May: Cahokia Mounds

A thousand years ago in downstate Illinois, across the Mississippi from where St. Louis is now, a world-class engineer designed a 100-foot-tall structure that still stands. He made it out of mud.

I think it's the most amazing destination in the Midwest. I wrote about it 15 years ago.

The latest visitor information is here.
