This album page documents a U.S. Navy crew's discovery and controlled demolition of a floating hazard at sea in the early twentieth century. Sailors rowed and motored out in ship's boats to rig explosive charges against the derelict, then photographed the resulting blasts from a safe distance. Handwritten captions -- "When First Found," "Setting the Explosives," "The Second and Last Explosion," and "After the First Explosion" -- narrate the sequence, offering a rare first-person visual record of routine but hazardous shipboard duty aboard USS Columbia.
