My business is urgent. I have bad news—very bad news, indeed! Obsidian
Creek, a small stream in Yellowstone National Park, is missing important
bugs—and I suspect foul play!
The larvae of stoneflies, to be exact—which spells trouble with
a capital “T!”
The absence of these creatures indicates Obsidian Creek is damaged—in
fact, it’s fatally flawed!
Alright, I’ll bite. What’s wrong with it?
