Where the Bison Roam

Act 1,  Scene 3,  Page 14 of 47

Bill’s last statement is not quite accurate, Inspector.

Mud Volcano, Dragon’s Mouth, and other hydrothermal features are located at the southern end of Hayden Valley. Rosie was not the only sign of life because plenty of microorganisms were living in these gurgling, bubbling mud pots and hot springs!

Individually, these microorganisms are so tiny that we can’t see them without a microscope. However, the bright colors found in the hot springs of Yellowstone are often due to billions of these tiny life forms clustered together.

I didn’t realize we were talking about bacteria, algae, and other single-celled life forms. Sorry, Therma, I stand corrected.

They’re important, Bill! Microorganisms may be about a million times smaller than plants or animals, but they shouldn’t be forgotten!

—tiny life forms such as bacteria, usually not visible to the naked eye
algae—photosynthetic microorganisms which are mainly aquatic and differ from plants because of a lack of true stems, roots, and leaves; algal (adj.)
