Abstract
Thermophiles
Thermophile is a fancy word for heat-loving organism. Thermophiles thrive in the run-off from hot springs and geysers in Yellowstone National Park. Often times, the color of the billions of thermophiles is different with the heat of the water. Therefore, the colors of the runoff from a heat source will change as the water cools when it moves further and further from the heat. This image is not a picture of two types of thermophiles, but of just one type. The orange is the color of the thermophile and the blue is the reflection of the sky in the runoff.
