"Vital signs," like blood pressure and pulse rate, are used in medicine to track human health. Paying attention to the little things can often help us better understand what's going on in the big picture. Scientists can monitor ecological "vital signs," too.

People travel from all over the world to see Yellowstone's famous geysers, colorful hot springs, burbling mud pots, and hissing fumaroles.
