Great Swamp National Wildlife Refuge Wilderness
Roughly 25,000 years ago, where the Wisconsin Glacier reached its furthest point south and stopped, the creation of Great Swamp began. With cattail marshes, wet meadows, swamp woodlands, and ridges thick with oak, beech, and laurel, Great Swamp provides a home for 39 species of mammals including mice, moles, skunks, raccoons, otters, foxes, white-tailed deer, and the endangered Indiana bat. Migratory birds see Great Swamp as a "nest and rest" (244 species have been identified). Numerous reptiles and amphibians have taken up residence, including rare bog turtles, wood turtles, and blue-spotted salamanders.

The outline is the agency boundary simplified for display, so small parcels and inholdings may not show. The agency page has the authoritative map.
Weather by month
Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
Where to camp
No federal campground is within ten miles of the boundary in the Campsite Atlas index. Camping inside a wilderness is usually allowed away from trails and water, with no facilities; the managing agency page has the permit and group-size rules.
