Meanwhile, high up in the Cascades and Olympics, so-called watermelon snow is making an appearance. The phenomenon is also caused by algae. This one is called Chlamydomonas nivalis, and it loves cold.
KING-TV recently interviewed a researcher at Western Washington University who studies watermelon snow. Robin Kodner, an assistant professor of biology, said the algae isn't new and can be found from Peru to the Arctic.
