Gene and Chris present Dr. Ardy Sixkiller Clarke, who returns to the Paracast to talk about her new book, “Sky People: Untold Stories of Alien Encounters in Mesoamerica.” According to the publisher’s notes, Ardy vowed as a teenager to follow in the footsteps of two 19th-century explorers, John L. Stephens and Frederick Catherwood, who were among the first to bring the ancient Maya cities to the world’s attention. She finally set out on her seven-year adventure in 2003 and traveled through Belize, Honduras, Guatemala, and Mexico, collecting stories of encounters, sky gods, giants, little people, and aliens among the indigenous Maya. She drove more than 12,000 miles, visiting 89 archaeological sites and conducted nearly 100 individual interviews. We’ll present some of the most fascinating tales during this episode.
