From a story in the Salem-News:

archaeologists explored the cavern near Lovelock, Nevada–the cave the Indians had described.

What the scientific researchers found was staggering: over 10,000 artifacts were unearthed including the mummified remains of two red-haired giants—one, a female 6.5-feet tall, the other male, over 8-feet tall.

The Paiutes, a Native-American tribe indigenous to parts of Nevada, Utah and Arizona, told early white settlers about their ancestors’ battles with a ferocious race of white, red-haired giants. According to the Paiutes, the giants were already living in the area.

Roaming, man-eating giants

The Paiutes named the giants Si-Te-Cah that literally means “tule-eaters.” The tule is a fibrous water plant the giants wove into rafts to escape the Paiutes continuous attacks.

They used the rafts to navigate across what remained of Lake Lahontan.

Giants roamed the Earth

According to the Paiutes, the red-haired giants stood as tall as 12-feet and were a vicious, unapproachable people that killed and ate captured Paiutes as food.

I have no opinion as to whether the findings confirm the legend or not. But I like the story.
