[1] Around 11,000 years ago, just at the end of the last ice age, migrating Paleo-Indian hunters camped at this site, probably following large game in the tundra-like zone near the retreating glacier.
Archaeologists at Madison told him this was unlikely, since Door County was still covered by an ice sheet at the time of the Clovis culture.
In 2003 archaeologists excavated sample pits the Cardy property, turning up more chipped stone tools and discarded flakes.
[4] 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.
[5][6] 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.
