Forensic geologist Scott Wolter, a real-life Indiana Jones, reveals that the history we all learned in school may not always be the whole story. Across the country, ancient symbols, religious relics and unexplained artifacts suggest that civilizations from around the world have left their mark for us to find today. Wolter not only digs through the surprising burial ground that is America for archaeological secrets, but he also uncovers compelling evidence that pre-dates the official "discovery" of the New World and turns a lot of what we think we know about American history on its head.
