It looked like the world’s largest bulldozer had been at work in the Straits of Mackinac, pushing thousands of tons of rare “blue ice” into mountainous piles near Mackinac Bridge. Actually, forces of nature—wind, waves, and the expansion of ice—teamed up to break the blue ice, drive it ashore and stack the broken sheets. This February 23, 2012 morning was the first time Brad and I ever saw the blue-hued ice. We had seen photographs of the rarely occurring natural phenomenon but thought they must have been taken in the arctic, not Michigan. Seeing is believing!
