The 433-foot flat deck barge Davy Crockett continues disassembly on the Columbia River, Wash., Ore., border on May 20, 2011. Metal is cut away from the floating stern section, transferred to a decontamination barge and then to a scrap barge to be hauled away. Meanwhile salvage divers prepare submerged areas for disassembly. U.S. Coast Guard photo by Petty Officer 2nd Class Eric J. Chandler.
