Lake Superior In January (10)

Blue ice is created in the human eye because absorption of light at the red end of the spectrum is six times greater than at the blue end. The deeper light energy travels, the more photons from the red end of the spectrum it loses along the way. Two meters into the ice, most of the reds are dead. The lack of reflected red wavelengths causes us to see blue.
