Striped Icebergs!!

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.

Thanks for the info...
I didn't know that icebergs could
have stripes... of course we don't see the bergs in Florida... but I
saw a few while in Alaska.

I've seen some shots of stripes in south pole ice -- but it didn't have the multi colors like this one. That is a mother nature art work!
