Turquoise Snow
We have been covered by 15.5 inches (39 cm) of dense, heavy, wet snow. I was surprised to see the inner layers had a bit of turquoise glow. We don't see this very often, our snow is typically loose and grainy.
Blue-green colors in the 'shadows' of snow is caused by the absorption of both red and yellow light, leaving light at the blue and green end of the visible light spectrum. This doesn't usually happen in 'loose' snow, but happens more often in ice and icebergs. This snow is particularly dense.
