Greenstone Ridge forms the backbone of this archipelago within Isle Royale National Park, where the land meets the cold expanse of Lake Superior. The survey illustrates a complex network of narrow channels and secluded harbors, including Rock Harbor and the sheltered Moskey Basin. Along the eastern shore, a cluster of smaller landmasses like Cemetery Island, where a cemetery is noted, and the twin East Caribou Island and West Caribou Island protect the inner waters from the open lake.
