4/27/14 & 4/28/14: This week on "Fieldnotes:"Watermelon Snow," by Boo Curry.

"In the Rocky Mountains' high-elevation snowfields and glaciers live some of the natural world's oddest creatures. Greek philosopher Aristotle reported seeing them 2,000 years ago.  Around the world, there are 350 species of these single-celled freshwater algae, surviving in melting snowfields and returning year after year to the same alpine locations. But what catches the eyes of hikers is that this species of green algea is not green, but red."
