Archaeologists are investigating claims about a long-lost group of giant humans who stood up to 10 feet tall and lived in caves in the southwestern US. 

Supersized human skulls, 15-inch sandals, and massive handprints have been uncovered in excavations inside a cave in Lovelock, Nevada since 1912 that have continued to spark the curiosity of scientists and the public more than a century.

The stories about these 'Giants of Lovelock,' came from Native Americas who told stories a brutal tribe of pale-skinned, red-haired invaders who waged war on the local tribes, before finally being trapped in a cave and exterminated.
