When we dig deep underground, we get a chance to dig deeper into history. Dennis Blanton wants to change the way we think about America’s beginnings. He’s studying the expedition of a Spanish conquistador who was the first European in many parts of the Southeast. And: At “The Cove” along the Staunton River in Virginia, Brian Bates and his students have uncovered nearly 10,000 items that paint a picture of a thousand year old Sappony Indians fishing camp.

Later in the show: Along with tools, pottery, and human remains, prehistoric sites are filled with ancient bird bones. Tal Simmons says these bones tell us what ancient humans ate, worshiped, and perhaps how they hunted. A discovery of seven prehistoric bird bone whistles might be the world’s oldest duck call. Plus: Before a state road gets moved or expanded, a team of archeologists comes in to dig for historical “treasure”. Elizabeth Monroe talks about a massive pile of oyster shells she uncovered and what they tell us about the people who used to live in the area.
