At Aztalan.

What's that almost at the top of the mound?

A native American village on the banks of the Crawfish River, with a surrounding palisade and several large ceremonial mounds. Occupied for about 400 years before suddenly disappearing around A.D. 1,300.

Perhaps the most important archeological site in Wisconsin. Aztalan was an offshoot of Cahokia (Illinois), one of the greatest cities of the world back about 900 years ago (bigger than London). People got from Cahokia to Aztalan by water—up the Mississippi, then up the Rock, then up the Crawfish, to a fertile spot where they grew corn, beans, and squash, fished the river, and hunted the surrounding woods.

We explored the palisades and climbed the mounds.

But of course, only after a fine breakfast at modern day Amalia's.
