Ice boulders or ice beach balls? What ever you call them they are rolling ashore along the Lake Michigan shoreline and they are getting a lot of press. Even the British Mail’s on-line publication called the Sleeping Bear Dunes area where these boulders are found the “coolest beach in America.”( Read story here.) Locals claim they have never seen them before. Apparently they are generated when an isolated ice crystal forms in the water column and as it’s sloshed around it picks up more and more ice. However they form, it’s neat to see that the Mitten State has another unique quality to it.
