The Paiutes, a Native American tribe indigenous to parts of Nevada, have an oral tradition that they told to early white settlers of the area about a race of red-haired, white giants or “barbarians” that their ancestors referred to as the Si-Te-Cah. The story was written down in 1882 by Sarah Winnemucca Hopkins, daughter of a Paiute Indian chief in her book Life Among the Piutes: Their Wrongs and Claims.

These “giants” were described as being vicious, unfriendly and cannibalistic. In this story, the Paiutes speak of a great battle that took place which led to their extermination at site known today as Lovelock Cave. During the early part of the 20th century, archaeologists found thousands of artifacts inside this cave leading to a lengthy excavation of the site and speculation that the Paiute legend was real.

The Paiute Legend of the Lovelock Giants and their Massacre at Lovelock Cave
Si-Te-Cah or Saiduka literally translates as “tule-eaters” in the Northern Paiute language. The tule is a fibrous water plant, which according to legend, was woven by giants into rafts in order to escape attacks by the Paiute. They used the rafts to navigate across what remained then of Lake Lahontan, an ancient lake that once covered most of northern Nevada during the last ice age.

As the Paiute tale goes, after years of warfare, all the tribes in the area joined together to rid themselves of the Si-Te-Cah. One day, as the tribes chased down the last remaining red-haired giants, they took refuge in a cave. The Paiutes demanded their enemy come out of the cave and fight, but the giants refused.

I followed up with an Archaeology World article. Both tell the stories, but are short on any scientific documentation. There are no new revelations in either article.

When I read the OP I had serious doubts. People need to double check stuff before posting anything.
