Coast Guardsmen use a parachute illumination flare to light a search area on ice and snow-covered Lake Michigan to help them find a person who fell through the ice as part of a night time training exercise Jan. 27, 2011. The training is part of a four-day school where men and women come from various units throughout the Coast Guard to the Ice Capabilities Center of Excellence at Station Saginaw River in Essexville, Mich., to learn the proper techniques for rescuing people on ice-covered bodies of water.
