In this October 2012 image from video provided by David J. Ruck, timbers that were discovered by Steve Libert, head of Great Lakes Exploration Group, in 2001 protrude from the bottom of Lake Michigan. On Saturday, June 15, 2013, Libert will lead a diving expedition to an underwater site in northern Lake Michigan, where archaeologists and technicians will try to determine whether the timbers and other items beneath layers of sediment are what remain of 17th Century French explorer La Salle's legendary Griffin.
