There was once a large settlement of people who lived next to the Crawfish River, in an area about halfway between Madison and Milwaukee. They flourished there from about 1050 AD to 1200 AD, then mysteriously vanished. The ruins were discovered by white settlers in 1835, and today the area is a state park. Take a look!
