Sno-Cone Icebergs on Lake Michigan


I have a friend that dearly loves sno-cones and if she had seen this “one” I might have had to restrain her from rowing onto Lake Michigan to consume this one. Actually, though, these are NOT sno-cones even if they look like them as they are colored stripes on icebergs found within Lake Michigan. How do they get to be this way?

Icebergs in Lake Michigan sometimes have stripes, formed by layers of snow that react to different conditions.

Blue stripes are often created when a crevice in the ice sheet fills up with melt water and freezes so quickly that no bubbles form. When an iceberg falls into the lake, a layer of water can freeze to the underside. If this is rich in algae, it can form a green stripe.

Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the lake. Interesting, is it not? Besides, if this were really a sno-cone, the price would be super expensive! But, boy would they ever taste good!
