"The Paiute tribe found in Nevada as well as Utah and Arizona has a legend that says that they fought white, red-haired giants who claimed the land before them.  The Paiutes and other tribes wanting to rid themselves of these vicious man-eaters joined together and finally cornered the last of this race in a cave.  They then set the entrance on fire, shooting with arrows those who tried to escape, while the rest asphyxiated.  The cave was sealed later by an earthquake and became a home to bats.  In 1924 the legend became credible.  A company mining the Lovelock caves in Nevada for saltpeter, a byproduct of decaying bat guano and ‘a chief ingredient of gunpowder,’ reported finding skeletons and artifacts to archaeologists.  Among these were ‘the mummified remains of two red-haired giants—one a female 6.5 tall, the other a male over 8 feet tall.’  In addition, in 1931 two more skeletons measuring over 8 feet tall were found in a dry lakebed near Lovelock, Nevada."
