Two members of the response team of Coast Guard Station Sault St. Marie engage in ice training exercises on an inlet near St. Marys River in northern Michigan. As many popular winter time activities on the Great Lakes involve venturing out on frozen waters, the Coast Guard's response teams must be proficient in a variety of rescue techniques. Here, members are simulating a rescue using a ice rescue sled and sling. The sled shields the body of the person being rescued and can serve as a stretcher.
