Colorful Icebergs

These icebergs have layers of various colors of ice from cracks that formed over time, and then fresh water and salt water seep in and then froze.

At least that is what I was told. However this happens it sure is beautiful.

This is the message that came along with the email that accompanied these amazing photos.

Amazing striped icebergs 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.
