The distinctly brilliant displays of colors of the pool are because of  bacteria that manage to survive in the often almost boiling hot water. In addition to admiring the colors, you may be luck to be there when underground volcanic pressures cause the Morning Glory Pool to spout as a small geyser.

When you visit Yellowstone, be sure to bring your camera to get the amazing other-worldly colors and currents of the Morning Glory Pool, the big geysers and other great natural sights.
