Hydrothermal system of the Yellowstone caldera. Palmer and Sturchio (1990): waters from -9.3 to +4.4 ‰; Norris and Upper Geyser basins, Calcite Springs and Clearwater stay close to fresh rhyolite (-5.2 ‰), Mammoth, Sheepeater and Rainbow near -8 ‰, like altered rhyolite (-9.7 ‰) or sediments outside the caldera. Water from drill hole Y-10, Angel Terrace and Narrow Gauge springs.
