Luke Caverns is an anthropologist and explorer who's mapped over 80 ancient archaeological sites using LIDAR — sites that don't appear on any map. His grandfather found and lost seven gold mines in New Mexico. Luke found them again. Now he's planning the largest LIDAR scan ever done in the Amazon. We also go deep into Alexander the Great's missing body, the Were Jaguar cults of the Olmecs, and the Minoan civilization that may have been Atlantis.
