U.S. Geological Survey


This U.S. Geological Survey website contains data from hydrologic monitoring of Tantalus Creek in Yellowstone National Park. Data from Tantalus Creek are important because it drains the Norris Geyser Basin. Stream discharge and temperature data are shown in graphs for the previous day, week, month, and year.
