I'm from Argentina and 1/8 indigenous.
In all the Americas, influence and even presence of indigenous cultures is omnipresent, even in whiter areas. We study it in schools, institutions and universities, and we celebrate the Discovery of the Americas on October 12th (most of countries).
However, I suspect that people in the other side of the pond only knows it superficially and mostly by movies. What do europeans know about native american peoples?
