Lake Michigan dominates this aquatic chart, which covers the expansive waters off the southwestern coast of the Manitou archipelago. A small portion of land is visible in the northeast corner of the sheet, representing the southernmost edge of South Manitou Island. The map illustrates the isolated position of the island within the larger basin of the lake, providing a clear reference for the open-water channels that separated these landmasses from the Michigan mainland during the early twenty-first century. Produced by the U.S. Geological Survey, this survey is primarily a hydrographic study of the depths and surrounding navigation routes south of the main island settlement.
