Joint POW/MIA Personnel Accounting Command forensic anthropologist Laurel Freas rechecks marker flag placement against her notes at the excavation site where a series of bore holes will be melted on a glacier near Koge Bay, Greenland, Aug. 13, 2013. Freas will use a subsurface camera to look inside the holes for evidance of a U.S. Coast Guard World War II-era J2F-4 Grumman Duck aircraft that reportedly crashed at that site on Nov. 29, 1942.
