In 1994 I saw a newspaper article that showed a photograph of a "huaco" (ancient pot usually made of clay, from the Inca culture or older). The sign that appeared on this "huaco" was a big svastika with four dots inside. This is a Vedic sign that you can see on the top of the gates of ancient temples. (Of course, the archeologists did not know what that symbol meant and maybe they still don't know it).
Also a devotee-scholar told me that he had seen another "huaco" that he described in this way: A monkey supposingly running or flying, holding a small mountain in one hand and a club in the other. The monkey had some kind of helmet. Sounds familiar doesn't it? Jaya Sri Hanumanji!
I've heard that some stories from Ramayana tell that Sri Ramacandra came to the American continent when he was fighting with Ravana & Kumbhakarna. This is very interesting point. When you go to Bolivia and to the south of Peru, you can see a very famous festival called "La Diablada" ("Demoniac Dance"). This festival depicts a very ancient story: two angel-like warriors fight against a ten-headed demon. This demon has a army and the angelical warriors are being helped by animal armies, especially by a society of well organized monkeys. Jaya Sri Ramayana!
I have also heard that the word "Dinka" means "Children of the Sun" or "Worshipers of the Sun" in Sanskrit or some other Indian language. The word "Inka" in Quechua (language spoken by the Inca culture) means "Children of the Sun". And worshiping the Sun gives the worshiper intelligence and gold, a very notorious feature of the Inca empire. Their society was very similar to varnasrama.http://www.veda.harekrsna.cz/connections/Americas.php#1
