Simplified Geologic Map of Yellowstone, modified from USGS I-711 by Marli Miller, University of Oregon. All rock material resulting from the major caldera-forming eruptions are labelled at Qt, where the dashed caldera boundary highlights the scale of these events. Older volcanic, sedimentary and metamorphic rocks are found outside of this boundary.

Map of earthquakes greater than M1.5 that occurred between March 1 and May 12, 2020, in the Intermountain West. The main shock-aftershock sequences in central Idaho and near Salt Lake City are labeled. Orange dots are earthquakes that occurred within 24 hours, and yellow 1 week, of the map being generated (May 12, 2020)

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).

Highly sensitive instruments installed deep below the ground surface yield great records of earthquakes near and far. The March 31, 2020, magnitude 6.5 Stanley, Idaho, earthquake shows up very clearly in borehole strainmeter station B944's four different sensors.

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
