The relationship between Δ30 and N2/3He ratios in hydrothermal gases from Iceland and Yellowstone. Δ30 and N2/3He ratios are shown for samples collected from gases in Iceland (yellow circles) and Yellowstone (red circles). The Yellowstone mantle-endmember is arguably indistinguishable in terms of N2/3He from the convecting upper mantle (grey diamonds).

Imperial Geyser hot spring pool in Yellowstone National Park is about 30 m (about 100 ft) across and contains alkaline-Cl waters with a steam vent in the pool and mudpots outside the pool area (in the upper right part of this photo). USGS Photo by Pat Shanks, 2019.

Mineral stability diagram showing minerals that are stable under changing temperature and dissolved silica concentrations that are found at and just beneath the floor of Yellowstone Lake. Two important points illustrated by this diagram are: (1) the minerals that are stable when reacted with vapor-dominated fluids (kaolinite, boehmite) differ substantially fro

The Yellowstone River is divided into five reaches (labeled and color-coded): Yellowstone Lake, Hayden Valley, Grand Canyon of the Yellowstone, Tower–Gardner, and Mammoth. Monitoring stations (yellow dots on map) between each reach of the river reaches allow geochemists to measure river composition and then determine the sources of chloride (Cl) and other solu

Map showing ice cover in the Yellowstone region. Light shaded areas bounded by black and red lines indicate areas covered during the Pinedale (about 20,000-15,000 years ago) and Bull Lake (about 150,000 years ago) glaciations, respectively. Blue lines are contours in thousands of feet on the maximum reconstructed Pinedale glacier surface.

A wide array of phototrophic microbial community textures exhibited in an alkaline (pH ~8.5) hot spring outflow channel in the Biscuit Basin, including thick mats, toadstools, ropes, and pinnacles. The differences in color are due to pigments (chlorophylls, bacteriochlorophylls, and carotenoids) produced by phototrophic microorganisms.

An unnamed small acidic (pH ~3) hot spring (with a temperature of about 55°C at the source) in the Gibbon Geyser Basin of Yellowstone National Park. The yellow region is due to the precipitation of sulfur by sulfide-oxidizing chemotrophic microorganisms.
