Visitors at Mount Lassen sometimes see pink “watermelon” snow in early summer.  The pink color comes from algae that grows on the snow’s surface as it melts in July.  There are over 350 species of snow algae around the world, ranging in color from red, orange, yellow, to green.  The algae supports an entire miniature world of worms and insects.  Scientists study life on the snow’s surface to see how life might survive on other planets.  More info on snow crystals is at:
