Look at these striped icebergs!!
Scroll down to see waves frozen on contact with the air!
Having the Internet means that we get to see something
that we never imagined! Pass it on for others to enjoy!
These really are amazing pictures. Looks like Alaska, not Michigan. Rita
Amazing 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.
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!!!
