ICE WAVES

In Antarctica (if you know where to look) you will find these strange formations that look like giant waves frozen in place.  Actually, these beautiful formations are caused by glaciers and earthquakes.  Over time, snow compacts into a single frozen mass and the increasing pressure squeezes all of the air out of the ice.  Since blue is the only color of the spectrum that air-free ice reflects, that is where the color comes from.
