Discovery of (NEW) 1,000-year-old Viking site in Canada could rewrite history
Ms Parcak looked at modern-day plant cover to find places where a possible Viking settlement had altered the soil by changing the amount of moisture in the ground. This was a technique she had previously used in Egypt.
After identifying a potential site, archaeologists found a hearth-stone, which was used for iron-working, near what appeared to have been a turf wall.
