"Geohydrobiology" of Yellowstone – where Earth, water, and life intersect!
April 23, 2018

"Geohydrobiology" sounds like a made-up word—as if the prefixes from multiple scientific fields were strung together to score big points in a game of Scrabble.

It is easy to understand why studying geohydrobiology is an important endeavor at Yellowstone, a place where Earth, water, and life intersect in unusual and stunning ways.

Read more about how Earth, water, and life come together in this week's edition of Yellowstone Caldera Chronicles!
