ATLANTIC OCEAN- (June 20, 2007) Two divers from the Coast Guard Maritime Safety and Security Team measure and mark an iron beam near Minot's Ledge Lighthouse, about four miles east of Scituate, Mass. The iron find is believed to have been structural support for the original lighthouse. This photo was taken by a remote operated vehicle, controlled by Petty Officer First Class Carl Shipley. The ROV was used in support of an archaeological survey dive in search of the remnants of the original Minot's Ledge Lighthouse, that collapsed into the sea in 1851 only one year after its construction.
