"Though the past winter was the hottest on record, it was chilly enough on the East Coast to send seasonal sheets of ice creeping across the Great Lakes. Now that that ice has cleared with spring, Lake Michigan is clear enough that shipwrecks lying on the lake bottom can be seen from the air."
"The U.S. Coast Guard Air Station in Traverse City noted the crystal clear water conditions and the lost ships during a routine patrol. Last week, they posted a handful of pictures to their Facebook page."
"For NPR.org, Bill Chappell reports that spotting wrecks from the air is "fairly common," according to one of the pilots on the patrol, Lieutenant commander Charlie Wilson, "but not in the numbers we saw on that flight." Chappell also notes that the Michigan Department of Environmental Quality writes, "An estimated 6,000 vessels were lost on the Great Lakes with approximately 1,500 of these ships located in Michigan waters."
