The Ottawa National Forest dominates this northern Michigan landscape, where the confluence of several major river branches dictates the terrain. The South Branch Ontonagon River and the Cisco Branch Ontonagon River wind through the timberlands, marked by water features like Eighteen Mile Rapids and the drop at Wolverine Falls. This 1980s-era survey reveals a topography heavily influenced by former industrial activity and forest management.
