1980 Map of Port Wing

Inland, the map tracks the historical transit corridors of the Northern Pacific RR and the Duluth South Shore and Atlantic RR, which helped establish towns such as Iron River and Poplar. The region is crisscrossed by numerous waterways, including the Brule River and the Amnicon River, which drops through Amnicon Falls State Park. This area showcases a late 20th-century balance between timber resources, conservation, and the quiet residential pockets around Lake Nebagamon.
