Cardy Site
The Cardy Site is located on the Door Peninsula south of Sturgeon Bay, Wisconsin. It was added to the National Register of Historic Places in 2010. History
The site once served as a home to Paleo-Indians. As the city of Sturgeon Bay expanded, part of the site was developed and due to the disturbance of the soil is no longer considered useful for archeological research. The remaining, undeveloped portion of the site was protected by the Cardy family beginning in 1960, added to the Wisconsin State Register of Historic Places in 2009, and today belongs to The Archaeological Conservancy. It is open to the public and listed as a point of interest near the Ice Age Trail. Further reading
