1956 Map of Lake Mary

About this map

The Michigamme River carves a central path through this mid-century landscape in Iron County, dictating the settlement patterns and industrial infrastructure of the region. The map captures the quiet transition of former mining and timber outposts, notably at Mansfield Location and the town of Mansfield. Evidence of the area's older commercial life is etched into the terrain by an Old Railroad Grade that skirts the northern marshes. To the south, the expansive waters of Peavy Pond and the Little Bull Diversion Canal illustrate a modified watershed, where natural lakes like Lake Mary and Mitchell Lake are integrated into a broader network of managed water. The presence of numerous smaller bodies, such as Erickson Lake and Glidden Lake, reflects a classic Upper Peninsula forest and wetland environment within the State Forest Boundary.
