NEW YORK (April 30, 2019) – For decades, Scott Wolter has honed his skills in the sciences looking for historical answers within the natural world. Now, he continues his quest for the truth on Travel Channel in the new season of “America Unearthed,” premiering Tuesday, May 28 at 10 p.m. ET/PT. In the 10-episode one-hour series, Wolter explores some of America’s deepest secrets, digging up mysteries that have been hidden until now. Using his background as a forensic geologist and teaming up with eyewitnesses and other experts in their respective fields, Wolter is determined to find new evidence and ultimately the proof that’s been buried in time suggesting history isn’t what we’ve been told.

“Every day, science finds something new,” said Wolter. “We find new species, discover previously unknown societies and learn that the world isn’t quite what we thought. There has never been a better time to use science to solve the mysteries of history.”

In the premiere episode, “Vikings in the Desert,” premiering Tuesday, May 28 at 10 p.m. ET/PT, Wolter receives a call about alleged Viking artifacts found in the Arizona desert. Using state-of-the-art XRF (X-ray fluorescence) identification technology and insight from a Viking historian, Wolter starts his search in the southwestern desert. From there, new leads take him to California to excavate a supposed buried Viking ship that might have once sailed America’s vast inland sea and to Mexico to examine a petroglyph depicting what could be Viking travelers. The episode produces some unexpected results and opens the door to further expeditions into where the Vikings went and why.
