Ancient Caucasians in pre-Columbian America

Indian tribes have legends of tall peoples living in the Americas in ancient times, before the Indians themselves. For example, the Paiute of Nevada have a legend of "exterminating" a light skinned red haired tribe who spoke a different language than themselves. In this area, red haired Caucasoid mummies have been found in caves, dated by archaeologists to over 9000 years old.
