Mackinac Wilderness is a 12,230-acre roadless area in Michigan’s Hiawatha National Forest near Moran that preserves a varied landscape shaped by Wisconsin glaciation, including moraines, sand dunes, creeks, wetlands, and the Carp River. Like much of the surrounding forest, the land was heavily clear-cut between about 1880 and 1910, then altered by fire and erosion, so the forest that grew back was second growth rather than old growth. Today it protects regenerating Upper Peninsula habitat, with aspen, birch, whitecedar, beaver ponds, and nesting birds, while also standing apart from nearby forest still managed for pulpwood production.
