I was told a few years back on a trip to Alaska that this kind of brilliant blue
ice is caused when it is under such tremendous pressure inside a glacier that
the air bubbles in it are literally compressed out and, since air-free ice
absorbs every color in the spectrum except for blue, the blue is reflected back
to our eyes.
Our guide said it best when he referred to icebergs like this one as,
"pieces of the sky that fell into the water."

That's how it was explained to me, as well. Even the meltwater rivers that
come off them keep the same blue color, but no one's ever been able to explain
that to me.
