Key Evidence
A tree-ring study dated Norse activity at L’Anse aux Meadows to 1021.
Christopher Columbus reached the Caribbean in 1492, creating a 471-year gap.
The site is in present-day Newfoundland, part of North America, although Indigenous peoples had lived in the region long before either event.

Archaeological evidence places a Viking, or Norse, settlement at L’Anse aux Meadows in Newfoundland in 1021. Researchers reached the date by analyzing tree rings from wooden artifacts at the site and identifying damage caused by a known solar storm.
