Chlamydomonas nivalis

Chlamydomonas nivalis is a species of algae that thrives in below-freezing temperatures. It causes pink- or red-colored snow in high elevation places where the snow cover lasts year-round. The color is from a carotenoid pigment that the algae have, in addition to (green) chlorophyll, and this pigment protect the algae from UV radiation at high elevation. The elevation range given above is for the Sierra Nevada in California - elevation range may be different in other mountains, depending upon their climate. The color becomes more intense when the snow is compressed, for example by walking on it. Source: Wikipedia.
