About this map

The vast expanse of Lake Superior dominates this portion of the Apostle Islands region within the northernmost reaches of Wisconsin. This 2011 survey illustrates the deep-water transition north of the shoreline, capturing the maritime environment as it was recorded at the beginning of the decade. The map serves as a specialized cartographic reference for the open waters of the Great Lakes, providing a precise look at the hydrography and navigational coordinates between the mainland and the outer islands of Bayfield County.
