Lumberman's Monument is a monument dedicated to the workers of the early logging industry in Michigan.
 Standing at 14 feet, the bronze statue features a log surrounded by three figures: a timber cruiser holding a compass, a sawyer with his saw slung over his shoulder, and a river rat resting his peavey on the ground.
 The granite base of the statue is engraved with a memorial that reads "Erected to perpetuate the memory of the pioneer lumbermen of Michigan through whose labors was made possible the development of the prairie states."
 It is also inscribed with the names of the logging families who dedicated their time and efforts to the industry in the area.
 It was built in 1931, dedicated in 1932 and is managed by the USDA Forest Service.
 It is located in the northeastern part of the Lower Peninsula of Michigan along the Au Sable River within Huron-Manistee National Forests.
