2013 Map of Michigan Island OE S

About this map

Lake Superior dominates this nautical-focused survey of the open waters southeast of Michigan Island in the Apostle Islands region. Produced by the U.S. Geological Survey, the map provides a precise bathymetric and hydrographic perspective of this portion of the Great Lakes in the early 21st century. The expanse shown here represents a critical navigation area within the Apostle Islands National Lakeshore, where the deep waters of the world's largest freshwater lake by surface area meet the complex underwater topography of northern Wisconsin.
