McCormick Wilderness is a federally protected wilderness area in Michigan’s Upper Peninsula within the Ottawa National Forest. Encompassing about 17,000 acres, it is one of three wilderness areas in the forest and includes headwaters of the Huron, Dead, Peshekee, and Yellow Dog rivers, making it important to the regional watershed. Though logged until the early twentieth century, the land has regenerated into conifer and northern hardwood forest, and moose have been reintroduced. The area is named for the McCormick family of Chicago, who assembled the tract between 1904 and 1920 and later willed it to the federal government in 1967, aiding its preservation.
