2018 Map of Cat Island

About this map

Apostle Islands National Lakeshore encompasses the isolated landmasses shown in this coastal survey, highlighting the preservation of these northern Wisconsin islands. Located within the cold waters of Lake Superior, the map focuses on the central and northern reaches of the Apostle Islands archipelago. The primary landform is Cat Island, which exhibits a series of internal section lines and topographic contours that indicate its varied elevation. Further north, the smaller North Twin Island stands alone, separated by open water. This 2018 edition uses high-resolution imagery to delineate the exact shorelines and protected boundaries of the national lakeshore, illustrating the spatial relationship between these remote islands before modern environmental shifts might alter their sandy spits and wooded interiors.
