If you went looking for Isle Phelipeaux in Lake Superior on a map today, you won't find it. However the phantom island was once thought to exist near Isle Royale.

The map above was produced in 1744 and titled Map of the Lakes of Canada - you can see the entire map here in the collection of Michigan State University.

The mistake island is located between Isle Royale and the Keweenaw Peninsula. Incredibly, even though the island doesn't exist, it was considered part of the border that defined the United States and Canada in the 1783 Treaty of Paris.

Isle Phelipeaux has also been called Isle Minong. That name, Minong, lives on describing a ridge of high land on Isle Royale.

It wasn't until 1820 when the border between the United State and Canada was being further surveyed that it was discovered that Isle Phelipeaux wasn't really there.

Incredibly, Phelipeaux isn't the only misplaced island in Lake Superior, there is also a legend of Copper Island a land that was said to once exist somewhere in the lake.

That's a lot of history for a patch of land that doesn't exist.
