Lucky that we have science. A few hundred years ago, people would probably have thought "Wow, blue snow, it must be magic, maybe if I eat it I will get God-like powers.", and then they would get ill by eating cyanobacteria.

Blue icicles...

 The W Road winds up Signal Mountain, and people who travel it often know the twists and turns of its hairpin curves.
