Lake Superior: Circling the Sweet Water Ocean

Discover Lake Superior, the largest lake in the world that straddles the U.S.- Canadian border, the two nations separated on the east side by a busy portage canal. The lake’s icy waters harbor a remote national park, Isle Royale, an island large enough to support a lake with its own island. Before the arrival of Europeans, Lake Superior was home to vibrant cultures and vigorous trade in copper.
