I saw blue snow once. I couldn’t tell it was blue at first because I have colorblindness, but one of my daughters pointed it out. I looked real close, and yup, it was blue. It fell during a very rare New England snowstorm that had lightning.

That was cool. A nice survival tip is that blue ice tends to be older which in turn means that much of the salt has leeched out. So if you are stuck at sea, need drinking water and see a blue iceberg, you are in luck!

So I'll reveal a bit more about my age. after the Titanic sank, I not that old!!!, the USCG took over iceberg patrols in the North Atlantic. In those days, and to an extent today but not so much, large ships traveling through the iceberg lanes used large bright flood lights on the bridge wings to look for icebergs in the vicinity of the ship. There are times when the iceberg does not have a show cap and is fairly clear. The light will refract through the ice, into the water and back out causing the berg to almost disappear. 
We used to go out in the C130's and also from the cutters and "bomb" them with fluorescent orange paint to make them reflect. While it was not effective because the bergs would roll and wash it off it was fun to throw the jars of die out and to shoot them with arrows from the cutters.

scheckydamon       Also in the Coast Guard, didn't make Ice patrols but did go to the artic and antartic on the Ice breakers Staten Island and Burton Island. I was told that the blue Ice was the oldest Ice and that it gets that way from like you said the lack of salt. And that it could be hundreds or even thousands of years old. An old eskimo told me that in a bar in Point Barrow Alaska. 
  I'll give you some Idea how old I am that was in the summer of 1974 or 1975 and I was a fresh face kid a couple of years out of high school.

casaledana If we are trying to figure out who the eldest of us IAB elder statesmen is I can say it's probably not me. For example, I was in kindergarten when JFK was shot whereas I'm pretty sure my friend semichisam was in kindergarten when Lincoln was shot.

victor02 Hopefully you are kidding, people have been going there to watch the glacial calving caused by the glacier expanding for a long time.

marsii Agreed. Also, I think the sounds of the trapped air rushing out of pockets in the ice is pretty amazing. Sounds like whales spouting.
