Glacier Mice: A Rolling Stone Does Gather Moss | Amusing Planet
- Glacier Mice form when moss starts growing around clumps of sand or a tiny rock lying on the glacier surface, and over time develops into a layer of moss. The moss continues to grow and insulates the glacier surface, resulting in the moss becoming elevated on a pedestal as the surrounding ice melts. Eventually, the moss falls from this pedestal which is then picked up by blasts of strong wind blowing across the glacier. These clumps of dust and organic matter roll around the vast sheets of ice like tumbleweed and the moss ends up growing on all sides. After years of growth, the clumps look like mouse-size green balls of vegetal fluff, and thus their name. Glacier Mice have been mostly documented over glaciers in Iceland, North and South America and the Himalaya.
