Alternative title: I shoulda taken an elective course in Geology.

My lack of knowledge in geology became apparent during a recent visit to Yellowstone National Park. The entire park seems to be volcanic. Hydrogen sulfide odors fill the air. Geysers spew, mud pots bubble, and hot springs boil. Do I know the definition of a fumarole? No. This may not even be spelled correctly.


Bubbling mud pot.




Warning signs tell you to stay away from the geologically active areas.

Old Faithful is right on schedule (plus or minus 10 minutes).

Thermophilic bacteria living in a hot spring. Finally, something this bio-nerd can understand.
