How does water from snow and rain get to the numerous hot springs in Yellowstone? Water molecules (H₂O) are made of two hydrogen atoms and one oxygen atom, but these atoms aren't always the same. Tracking how these atoms in water molecules differ is a powerful tool for tracing where snowmelt or rain seep into the ground, how water flows beneath the ground, and how long does water flow until the arrives at a hot spring.

Some like it hot! Studying thermophiles in Yellowstone National Park Thermophiles thrive in hydrothermal features where scalding temperatures would burn other life. What can we learn from the unique adaptations of these heat-loving microorganisms?
