About this map

National City and the neighboring settlement of McIvor anchor this landscape along the border of Iosco and Arenac Counties. The terrain is defined by a dense network of hydrologic features designed to manage the low-lying, wetland-heavy geography of northeastern Michigan. Watercourses such as the Au Gres River and its branches, including the E Br Au Gres River, wind through a mosaic of forested land and expansive marshes like Messer Swamp and Alabaster Swamp.

Evidence of local land reclamation and agricultural engineering is visible in the numerous named drainage systems, such as Sherrit Drain, Laundrie Drain, and Scott Drain. These features, often following the section lines of the Public Land Survey System, illustrate the historical effort to utilize the wet soils of the region. Small communities like Turtle are connected by a grid of rural roads including Whittemore Rd and Turtle Rd, reflecting a settlement pattern deeply tied to the drainage and clearing of the surrounding woodlands.
