1932 Map of Burnt Bluff SW

About this map

St Martin Island and its lighthouse, St Martin Lh, mark the southern reaches of this maritime survey where the waters of Green Bay and Lake Michigan converge. The archipelago featured here represents a vital navigation corridor in the early 1930s, defined by the isolated outposts on Summer Island and the smaller Poverty Island. The map records the strategic placement of government infrastructure, including the Poverty L H and several Lake Survey markers like Usls Miva. Settlement is sparse, limited to landfalls like Fairport on the mainland tip and small clusters such as Little Summer. The inclusion of surveyed section lines across these islands indicates the era's ongoing effort to categorize and control these remote northern landmasses for maritime safety and resource management, just as aerial photography began to revolutionize topographic mapping.
