At the Explorium, you can tour the Horicon Marsh through time — from the Ice Age and to present day — through our narrated, interactive exhibits.

Long before Horicon Marsh achieved international status as an important bird and wildlife area and a destination for outdoor recreation, glaciers carved a basin where a wetland would one day form. Today, guests of Horicon Marsh’s Explorium can get a glimpse of life at Horicon Marsh thousands of years before European settlement and witness how the current wetland came to be.

The experience is narrated by a Clovis spearpoint, who keeps visitors company throughout the journey as they view, listen to, touch, and even smell exhibits that document the changes to the marsh over time.  Videos and interactive displays greet guests at every turn, encouraging audiences of any age to learn more about the history and ecology of Horicon Marsh.
