Gwinn and its surrounding Upper Peninsula settlements occupy the convergence of the East Branch Escanaba River and the Middle Branch Escanaba River. This 2017 survey details a landscape where industrial history and modern infrastructure coexist, from the S Francis Mine Dr to the expansive Sawyer International Airport in the northeast. The residential patterns in New Swanzy, Princeton, and Austin reflect the township's development alongside the river system and local resource extraction. To the south, the water-dominant terrain is marked by the Boney Falls Basin and numerous glacial lakes, including Johnson Lake, Bertrand Lake, and Shag Lake. Local history is anchored at the Gwinn Cem and Lesterson Field, while the dense network of county roads like N Co Rd 557 and Co Rd EEB provides a clear view of the modern transportation layout in Forsyth Township.
