Cool



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 meltwater 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.
This is a picture of a wave, frozen as soon as it hit the air.
Aren't these pictures cool?
No pun intended.

I've never seen any pictures like this. How interesting. Isn't the world an intricate place that's full of wonder?

Very cool pictures! The frozen wave and the smooth, whale looking striped berg are my favorites. How'd you come by these awesome pictures? And is that you in the forefront of the frozen wave? Can you imagine trying to surf and the wave just freezing under your board? (Ha, ha! I'm joking. I'm totally joking!)

Someone emailed these to me a while ago; I was amazed....They are dramatically beautiful.
