Grand Prismatic Spring I

As hot mineral water seeps out of the Grand Prismatic Spring in Yellowstone National Park it leaves tiny layers of minerals.  The heat of the water provides an ideal environment for bacteria, which grow in colorful mats over the wavy mineral deposits.  The end result is an amazing display of color and texture.
