Phélipeaux and Pontchartrain
Phélipeaux (also: Phelipeaux , Philippaux ) and Pontchartrain were two phantom islands in the Upper Lake that first appeared on a map by the Parisian cartographer Jacques-Nicolas Bellin in 1744 .
They were later adopted by other cartographers, including John Mitchell in 1755 . This so-called Mitchell map was the basis for the future demarcation of the boundaries between the USA and British Canada during the peace negotiations in Paris in 1783 . Accordingly, Phélipeaux was added to the USA, Pontchartrain to the British crown.
The two islands, which were shown only slightly smaller than the actually existing Isle Royale , could not be found by later expeditions and disappeared from the maps from 1824. Today it is believed that Bellin invented the islands in honor of his patron Louis Phélypeaux , Count of Maurepas and Pontchartrain.
