Striped Icebergs

Icebergs in Lake Michigan 

They 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!!! 


Having the  Internet means that we get to see something 
that we  never imagined!   Pass it on for others to enjoy!
