2022 Map of Cat Island

About this map

Apostle Islands National Lakeshore encompasses a series of secluded landmasses within the cold waters of Lake Superior. This topographic study highlights the isolated northern archipelago known as the Apostle Islands, specifically focusing on the landforms of Cat Island and North Twin Island. The map illustrates the shoreline contours and interior elevations of these islands, which are managed as part of the National Park System. The absence of roads or permanent settlements reflects the preservation of these islands as a maritime wilderness, where the natural environment is defined by Lake Superior's expansive surface and the discrete boundaries of Public Land Survey System townships t53n r2w and t52n r2w.
