National Park Week: Yellowstone

This colourful image is from the Painted Pot Nature Trail in Yellowstone National Park. The colours are bacteria in the water run off from Silex Spring that can be seen in the back left of the image. Some bacteria and thermophile microorganisms can survive in hot springs at temperatures greater than  70 C or 160F! The different colours are from different bacteria.
