Monitoring Hydrothermal Features


Did you know Yellowstone monitors the temperatures of hydrothermal features? Employees like Mark deploy and maintain an array of thermistor (temperature) data loggers often placed in the near-boiling, acidic runoff channels of hot springs and geysers across the park. The data collected over time is analyzed for patterns, which help us determine a variety of things like eruption intervals or if nearby features may be connected underground.

“It’s interesting to see how hydrothermal activity in certain features change over time. We’re always learning something new, and sharing that information with folks I meet on the boardwalks is one of my favorite parts of the job.” – Mark Wolf, Physical Science Technician
