About this map

National City and McIvor serve as the primary rail-side settlements in this corner of Iosco County, defined by a landscape of industrial extraction and managed timberlands. The Detroit and Mackinac RR cuts through the terrain, connecting the scattered homesteads to larger markets while passing several large quarries near the southern border. These industrial sites, alongside a Townhall and the Sherman Sch, indicate a community built around the intersection of resource labor and local governance.

Extensive wetlands like Messer Swamp and Alabaster Swamp are threaded together by a complex network of man-made drainage, including the Sherrit Drain and McMullen Drain, flowing toward the Au Gres River. Much of the acreage is designated as the Mackinaw State Forest and Au Sable State Forest, reflecting the era's emphasis on forest conservation and regulated land use in Michigan's Lower Peninsula.
