I could see the Norse trading steel knives, wool cloth, etc to the natives in exchange for tusks and furs.
My big question comes from all we’ve heard about 16th century Europeans bringing smallpox and measles, and wiping out native populations through disease, why didn’t it happen with the Norse interactions? Were the Thule tribes too spread out and isolated for plagues to easily spread?
Maybe because the Norse were fastidiously clean people?
