Around the turn of the 19th century, there were hundreds of reports from reputable sources of giant skeletons unearthed from ancient burial mounds across America. Researcher and author Jim Vieira has made it his mission to explore the mystery behind these mounds and others where there is documentation of unearthed skeletons, often of gigantic proportions. He found that the construction, and particularly the stonework, of these mounds, was impressive, considering the level of technology at the time and many had the remains of giants buried beneath them which ranged from 7 to 10 feet tall.
