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. 


Frozen Wave Pixs - Nature is amazing! 

The water froze the instant the wave broke through the 
ice. That's what it is like in Lake Michigan where it is the 
coldest weather in decades. Water freezes the instant 
it comes in contact with the air. The temperature of the 
water is already some degrees below freezing.

Just look at how the wave froze in mid-air!!!
