The Lumberman's Monument is about 20 miles west of Oscoda, Michigan. It is part of the National Forest in that area. It was built in 1931 as a monument dedicated to the lumbermen of Michigan.
Lumber used to be one of Michigan's main industries until the forests were pretty much depleted. As a result of that, they learned better forest management techniques and lumbering is still a part of Michigan's economy although not as large as it used to be.
This is a shot from behind the monument. The river is the Au Sable River. It used to be a major artery for the lumber industry. Now it is a fairly major river for canoeing.
