Saint Martin Island emerges in the lower quadrant of this offshore survey, marking a significant waypoint in the waters between the Garden Peninsula and the Door Peninsula. This chart focuses on the maritime environment of Lake Michigan, where the narrow Saint Martin Island Passage provides a critical navigable route for vessels moving between the open lake and Green Bay. The map captures the island's topography in detail, showing its elevation contours and the surrounding shoal waters. As part of the t36n r20w township designation within Delta County, this sparsely documented area highlights the isolated nature of these mid-lake landmasses, which have historically served as vital aids to navigation for the Great Lakes shipping industry.
