If that’s Greenland and the other one is Iceland, I think it says bad things about Viking naming abilities. After all the rape, loot and pillage I guess naming places was not a big priority with them.
Either that, or it was a 10th century land fraud of some kind. Iceland is about 5% covered with ice, Greenland is about 90% covered with ice. Hmmm.
The naming was purposefully done that way to keep away invaders.
