    Wow! Frozen Wave Phenomenon on Lake Huron

    Michigan has had the coldest winter in decades. Water expands to freeze, and at Macinaw City the water in Lake Huron below the surface ice was supercooled. It expanded to break through the surface ice and froze into this incredible wave.

    This wave phenomena is seen in Antarctica, but in Michigan? Yes, it's been quite a winter!

    Amazing Striped Icebergs

    Icebergs in the Antarctic area 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 sea, a layer of salty seawater 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 sea.
