Ancient Indian Giants

A modern myth has been circulating about a prehistoric tribe of gigantic, fair skinned, red haired Native Americans. It is claimed these giants were from an ancient tribe that predates the historical tribes. They are said to have been eight plus feet tall and extremely aggressive cannibals. Often this myth has the giants driven off by normal sized natives when they moved into their historic tribal lands or that they hunted them to extinction simply in order to survive.
