The Mackinaw State Forest dominates this Alpena County landscape, where the Thunder Bay River and its South Branch converge amidst extensive wetlands. The terrain is defined by its water systems, from the expansive Fletcher Pond and Upper Pond in the south to the Long Swamp and Long Rapids in the north. The presence of an Old Railroad Grade cutting through the forest provides evidence of the region's earlier industrial logging era, long before these lands were protected for state conservation.
