2017 Map of Todd Harbor

About this map

Isle Royale National Park dominates this 2017 survey, showcasing the geological parallel of Minong Ridge and Greenstone Ridge on Michigan’s northernmost wilderness island. This landscape is defined by its deep linear valleys and ridges that trend southwest to northeast, trapping interior waters like Hatchet Lake and Lake Harvey between the heights. Along the shoreline, Lake Superior cuts into the rocky coast to form Todd Harbor and Florence Bay, shielded by a series of small landforms including Wilson Island and Taylor Island. The elevation reaches its peak at Mt Siskiwit, overlooking the expansive Siskiwit Lake to the south. This mapping provides a clear look at the remote archipelago’s complex topography, from the precarious Teakettle Island to the northern reaches of Kamloops Point, where the shoreline meets the open water of the Great Lakes.
