A remote forested island in Lake Superior preserved as a U.S. national park, famous for its long-running wolf and moose study.
Geography
Isle Royale is the largest island in Lake Superior, stretching about 72 km long and 14 km wide. Hundreds of smaller islets fringe its shore. It is reached only by ferry or seaplane and closes entirely from November through April.
Ecology
The Isle Royale Wolf-Moose Project, begun in 1958, is the longest continuous predator-prey study in the world. Wolf numbers crashed to two by 2018, prompting reintroductions by the National Park Service.
History
Prehistoric Indigenous miners worked copper deposits here as early as 4500 BCE. Commercial fisheries and copper mines operated from the 1840s until the island became a national park in 1940.
