National City and the neighboring settlements of McIvor and Turtle anchor this landscape along the border of Iosco and Arenac Counties. The area is defined by a complex network of waterways and drainage systems, where the Au Gres River and its branches, including the E Br Au Gres River and W Br Au Gres River, wind through low-lying terrain. Extensive wetland areas like Messer Swamp and Alabaster Swamp dominate the northeastern and eastern portions of the map, illustrating the persistent hydrologic character of this part of Michigan.
