Growing up in Fort Atkinson, WI, we periodically visited the local Indian Mounds in Indian Mounds Park as a school trip. There are eleven mounds consisting of tapering linear, conical, bird and turtle mounds. I found them fascinating back when I was 10 but I never thought I’d be studying Indian civilization when I was all grown up! Here is a list of Indian mound parks in Wisconsin (You have to scroll down to Jefferson County for Fort Atkinson.). The Princess Mound is at the Lake Mills Aztalan Museum at the Aztalan State Park, the site of a ceremonial and residential Native American town established around 1100 AD.
