What happened
On a narrow terrace above Epaves Bay at the northern tip of Newfoundland, Norse sailors built eight wood-framed, sod-covered buildings, including three dwellings, a forge, and workshops for iron production and ship repair. Archaeologists excavating the site from the 1960s onward recovered around 800 wood, bronze, bone, and stone artifacts confirming Norse origin, similar in construction to Norse buildings found in Greenland and Iceland from the same period. In 2021 a team led by Michael Dee used a different method: they identified a spike in radiocarbon caused by a solar storm in 993 CE preserved in tree rings worldwide, then counted growth rings outward from that marker on three wood pieces cut by metal tools at the site. All three trees had been felled in exactly 1021 CE.
Why it matters
L'Anse aux Meadows is the only site in the Americas outside Greenland where archaeology confirms pre-Columbian European presence, roughly 500 years before Columbus. The 2021 dating is the most precise calendar date ever established for any pre-Columbian European activity in the Americas, and shows the Norse were capable of transatlantic voyages, timber harvesting, and iron production at a specific, dateable moment.
How we know
The 2021 Nature study used the globally synchronized radiocarbon spike from the 993 CE solar storm as a fixed marker in the wood's growth rings, then counted rings to the bark edge on three different felled trees, all of which independently returned the year 1021.
