Colourful Bacteria Growth

One of the colourful images that I captured at the Yellowstone National Park is an image of bacterial growth at the edge of geyser. Most of us will not expect any live organism at such a high temperature. On the contradictory is not true.
In terms of the microbes, scientists discover thermophiles, as the name implies, are thermal-loving.
The growth has provided me with an out this world image if you are imaginative enough. A visit to the Park, will give you an endless opportunity of capturing this kind of images.
