FILE - In this June 15, 2013, file photo, explorer Steve Libert speaks on a fishing boat as dive teams prepare to inspect a site in northern Lake Michigan. Libert, who has searched 30 years for the French explorer La Salle’s lost ship the Griffin, hauled a nearly 400-pound beam ashore in June. The timber has been examined by U.S. and French experts and underwent a hospital CT scan and carbon dating to determine its age and whether it once was part of a vessel. Nearly a year later, reports obtained by The Associated Press and interviews with key players reveal sharp divisions over whether the elusive ship has been found. (AP Photo/John Flesher, File) less
