Ice Land

During late Winter, Ice begins to break up on Lake Superior and gets pushed into piles along the shoreline.
In ice, the absorption of light at the red end of the spectrum is six times greater than at the blue end. Thus 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. A lack of reflected red wavelengths produces the color blue in the human eye
