The Art of Yellowstone Algae

The Art of Yellowstone Algae

Yellowstone National Park is a geologic wonderland and one of the most unique places on earth. More than a third of
Yellowstone Park sits within the caldera of a giant, ancient and still active volcano. I admit, I was having second thoughts
just before my feet touched ground in this amazing park. All around the park - steam is being released from the earth and
vents shoot boiling water more than 300 feet into the sky. It was quite something to behold. But when you start to look
closely at the colourful geothermal springs, you realize that the colourful algae of Yellowstone Park are actually varieties
of microbes. Hot Springs originate from the same geothermally heated water as geysers do, but in this case, they do not
have a constriction that builds up pressure, so they bubble or flow continuously rather than erupt. Hot springs are the most
common type of hydrothermal feature in the park, and they can be found throughout the geyser basins and elsewhere.
