It was the great glaciers of the last Ice Age that gave rise to this marshland basin. Since these early origins, it has been home to an abundant variety of fish, birds, and other marshland wildlife. Evidence indicates that man was already here when this marsh was in its infancy. Over the years, more than 265 species have been sighted here and this marsh regularly attracts some of Wisconsin’s rarest birds. Being a National Wildlife Refuge, public access is limited in this portion of the marsh in order to protect the wildlife for which it has been established. Most of the state area is open to the public. One of the best ways to explore this area is by canoe or shallow draft boat, but please be aware of restricted use and closed areas.

Along with hiking, hunting and fishing, you can also study the wildlife from the water in a boat or canoe. Four-mile Island is a protected area for nesting Herons and Egrets that quiet observers will find fascinating.
