Nearly a thousand years ago, America's first city appeared in the Mississippi flood plain. Don finds out about a day in the life of Cahokia, what its vast mounds were used for, and why it is so poorly remembered nowadays.

Our guest is Timothy Pauketat, archaeologist and author of several major books about Cahokia. His latest book is called Gods of Thunder: How Climate Change, Travel, and Spirituality Reshaped Precolonial America.
