2023 Map of Todd Harbor

USGS Topo · Published 2023

About this map

Isle Royale is documented here as a preserved wilderness within Lake Superior, highlighting the complex shoreline and interior highlands of Keweenaw County. The landscape is defined by the parallel elevations of Minong Ridge and the Greenstone Ridge Trl, which stretch across the island and dictate the orientation of its inland waters. Within these ridges, significant water bodies like Hatchet Lake and Lake Harvey are shown, along with the extensive shoreline of Siskiwit Lake at the southern edge. Along the coast, the map details numerous maritime features including Todd Harbor, Florence Bay, and Pickett Bay. Offshore, the survey identifies several small landmasses such as Wilson Island, Taylor Island, and Kamloops Island, as well as Ryan Island within the larger interior lake. This map serves as a contemporary record of the Isle Royale National Park boundary and its protected interior Isle Royale Wilderness.
