Yellowstone Hot Spring

Yellowstone Hot Spring  Well yes, another Yellowstone image; just can’t help myself.  it’s one of my favorite places to visit.  Hot springs are the most common hydrothermal feature in Yellowstone.  The bright colors found in Yellowstone’s hydrothermal basins come from thermophiles; microorganisms that thrive in hot temperatures. Trillions of microorganisms grouped together appear as masses of color.  Different types of thermophiles live at different temperatures within a hot spring providing distinct gradations of living, vibrant colors.
