The history behind this season.
How far did the real voyages reach?
Norse settlements connected Iceland and Greenland, and archaeology establishes a presence in Newfoundland. Wood from L’Anse aux Meadows provides a precise date of activity in 1021; it does not date the first arrival.
Keep the distinctionFloki and Ubbe’s screen journeys should not be used to identify the crews at an archaeological site.
