Forensic geologist and Travel Channel host SCOTT WOLTER joins us to discuss his new season of "America Unearthed."  We will be weaving earlier episodes with his books "The Hooked X" and "Akhenaten to the Founding Fathers."  Of course, we will be covering different waves of migrations to the North American continent.  What are the differences between the shows?  What new directions is the show taking?   And there are all of the unusual artifacts.  We'll cover them too.  Get some behind the scenes info on Scott's very popular series.rcott Wolter
