Vikings in America

In 1963, archaeologists found Viking ruins in Newfoundland predating Columbus by 500 years. Leif Ericson, Icelandic explorer, second son of Eric the Red, is believed by most historians to have been the first European to reach the North American mainland. About the year 1000 he landed at a place that he called Vinland. Vinland was identified as Newfoundland in 1963 when archaeologists uncovered the remains of a Viking-type settlement at L'Anse-aux-Meadows at the extreme northern tip of the island. His countryman, Bjarni Herjólfsson, had earlier sighted North America and reported that the land was rich in timber. Thus, Ericson had a clear economic motive for his journey. Icelanders needed wood for houses and ships, but their country is entirely treeless.
