Alaric Posted December 28, 2017 #3 Share Posted December 28, 2017 Cyanobacteria “The blue is most certainly pigment from cyanobacterial cells that have been broken apart by freezing. Most cyanobacteria contain two intensely blue pigments, phycocyanin and allophycocyanin. Sometimes they contain a third pink pigment called phycoerythrin.“ http://lakeice.squarespace.com/2014-blog/2013/12/7/blue-ice.html 1 Link to comment Share on other sites More sharing options...

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. 2 Link to comment Share on other sites More sharing options...
