They didn't stick around nor even told other Europeans about a New World so their impact on the settlement of America was ZERO.
Then why bother and even ask the question dumbass if you have your canned response ready?
The story goes when the Native Peoples saw these monster boats coming from the sea. They fled in panic to the villages and told of beasts with horns being born from these big beasts of the sea. The Vikings did not know where they where and facing over 5,000 very scared people. The warriors of the tribes came and massacred everything that belonged to the Vikings. They never returned home, were Columbus did. That is the difference in history.

I’ve read knowledge of the Vikings’ route WAS published in sea voyager circles, and was a reference for Columbus, among many others, influencing his navigation.
