Wasn’t there some evidence that the Vikings made it down to Maine and Mass.?
They did find some nuts at L’Anse Meadows that originated on the N.A. mainland.
It is interesting to note that the planet was much warmer during this period, which was followed by the little ice age which drove out the Vikings.
It also looks like the sea was about a meter higher when they settle in Newfoundland. That rise of the land..or sea going down, could have been casued by the land rebounding after the glacier age.
Great place to visit..
Actually, there's the Kensington Rune stone from around Northfield Minnesota. Isn't amazing how the Norwegians settled Minnesota twice, a thousand years apart, and left no evidence of their first travels anywhere else? Couldn't be a fake.
