There is a large body of maps of the Americas which cannot be explained by known explorations. Mercator’s 1569 World Map shows all of Greenland without ice at its coasts. Finaeus’ 1531 World Map shows Antarctica without coastal ice, all Greenland without coastal ice and an ancient shoreline of Hudson Bay. No 16th-century explorer could have reached Antarctica and Northern Greenland during this time period, much less have seen them ice free at their coasts.
