Isle Phelipeaux
Phantom island in Lake Superior / From Wikipedia, the free encyclopedia
Isle Phelipeaux or Isle Philippeaux – also called Isle Minong[1][2] – is a phantom island supposedly located in Lake Superior. In the late 18th and early 19th centuries, it was believed to be real, and was shown on maps of the era. The island "Phelipeaux" is mentioned in the 1783 Treaty of Paris as a landmark defining the border between the United States and what would later become Canada.
It is thought[by whom?] to be either a fabrication or a mistaken duplication of Isle Royale. Other prominent islands appearing on contemporary maps of Lake Superior which may or may not correspond to real islands are Pontchartrain, Maurepas, and St. Anne's.[3][4]
