A roadless, river-centered wilderness in Michigan's Upper Peninsula, where wetlands, beaver ponds, and glacial moraines shape a working example of northern forest recovery.
Mackinac Wilderness
The Mackinac Wilderness is a roughly 12,230-acre roadless unit located within the much larger Hiawatha National Forest in Mackinac County, in Michigan's eastern Upper Peninsula. It is formally classified as an IUCN Category Ib wilderness area and stands apart from most of the surrounding national forest because it has been set aside from active timber management, allowing ecological processes to play out largely on their own.
The unit is shaped by the Carp River, one of Michigan's designated National Wild and Scenic Rivers, along with the wetlands that line its drainage. Surrounding terrain is dominated by postglacial moraines, sand dunes, and sandy ridges left behind by the Wisconsin glaciation, creating a landscape of creeks, ribbon-shaped marshes, beaver ponds, and second-growth aspen and birch forests.
The Mackinac Wilderness is jointly managed by the U.S. Forest Service and the Ojibwa (Chippewa) tribe, reflecting the broader Indigenous heritage of the eastern Upper Peninsula. It is accessible from the M-123 highway but remains a predominantly undeveloped, trail-sparse area in which natural succession, rather than forest management, drives the visible character of the land.
