Greenland is North America

Did you know that Greenland is a part of North America? Maybe I'm a case for remedial geography class but this was news to me. Actually, I had never really thought about it.

This fact is why Claudius Clavus's original manuscript map of Scandanavia, which is the earliest map known to have shown Greenland, is so important. It is the first European map to show North America. Clavus made the map while he was exploring the area in about 1410, 82 years before Columbus "discovered" America. Learn more here
