Solar storm confirms Vikings settled in North America exactly 1,000 years ago
Analysis of wood from timber-framed buildings in Newfoundland shows Norse-built settlement 471 years before Columbus
Long before Columbus crossed the Atlantic, eight timber-framed buildings covered in sod stood on a terrace above a peat bog and stream at the northern tip of Canada’s island of Newfoundland, evidence that the Vikings had reached the New World first.
But precisely when the Vikings journeyed to establish the L’Anse aux Meadows settlement had remained unclear – until now.
A new type of dating technique using a long-ago solar storm as a reference point has revealed that the settlement was occupied in AD1021, exactly a millennium ago and 471 years before the first voyage of Columbus. The technique was used on three pieces of wood cut for the settlement, all pointing to the same year.
The Viking voyage represents multiple milestones for humankind. The settlement offers the earliest-known evidence of a transatlantic crossing. It also marks the place where the globe was finally encircled by humans, who thousands of years earlier had trekked into North America over a land bridge that once connected Siberia to Alaska.
