Very well, let’s talk about both Obsidian Creek and the
Firehole River. The first thing you need to know is that the information
you saw on Obsidian Creek was incomplete and I now have additional data
to round out the story.
Here is a chart showing recent average temperatures and pH
levels at each of the Obsidian Creek sampling sites. I remind you that
pH indicates how acidic
or alkaline the water is.
Car battery acid has a pH of 1, household ammonia cleansers rank 11, and
pure water is neutral with a pH of 7. Although there are exceptions, most
living creatures cannot tolerate living for very long in acidic conditions
where the pH is less than six or in alkaline conditions where the pH is
greater than eight.
Aha! Here is proof positive that most life forms cannot live in Sites
3 and 4!—the conditions would be similar to hot vinegar or lemon
juice! How dare the Yellowstone Ministry of Mysteries conceal
that this vile stream exists in Yellowstone National Park—a place
that is supposed to be preserved in its natural state! Let’s sue!
much does the temperature change between Site 1 and Site 4?
