WATERMELON SNOW

By: JuliaWeather, 3:07 AM GMT on January 06, 2014

WEATHER FACT: snow isn’t always white. In California’s Sierra Nevada mountains and the alpine region of Colorado (and other high altitude areas around the globe) pink snow is occasionally spotted. It’s caused by a microscopic reddish-colored algae that thrives in freezing water. This sometimes dark red snow puzzled mountain climbers for centuries. Also known as watermelon snow, blood snow, red snow and snow algae, the first accounts of watermelon snow are found in the writings of Aristotle. http://en.wikipedia.org/wiki/Watermelon_snow
