Spectrogram of a possible long-period (LP) earthquake in Yellowstone that occurred on August 26, 2021, near Norris Geyser Basin. The top panel shows a 30-second seismogram recorded at seismic station YHH. The bottom panel shows the spectrogram with energy concentrated in the 1–3 Hz range and lasting for ~15 seconds.

Spectrogram of a typical volcano-tectonic (VT) earthquake that occurred near Norris Geyser Basin, in the same region similar depth as the possible long-period (LP) event that was recorded on August 26, 2021. The top panel shows a 30-second seismogram recorded at seismic station YHH. The bottom panel shows the spectrogram with energy ranging from 1-15 Hz

Landsat 8 nighttime thermal infrared image of Yellowstone from 28 January 2022. Inset images are zoomed in on the area outlined by the white square. Inset image (A) has the raw data values, which range from 9070 to 21284. Inset image (B) shows the same image converted to spectral radiance, where values range from 3.13 to 7.21 W/m2/micron

Left photo shows a loose piece of siliceous sinter that was precipitated around a photosynthetic microbial mat in the Lower Geyser Basin. The microbial mat died when the outflow channel changed positions.

Castle Geyser features and Scanning Electron Microscope image of algal filament in a silica sheath
linkOn the left is Castle Geyser during an eruption with a pool from nearby Tortoise Shell Spring showing photosynthetic pigments at the bottom. The middle image is of a small pool in the Geyser Hill Group in the Upper Geyser Basin with an outflow channel full of yellow, green, orange, red, and brown pigmented phototrophic microbial mats.

Scarp of the Uhl Hill fault. Photo (top) is looking west at the east-facing fault scarp, with a geologist at the top of the scarp for scale. Here, the fault cuts through Pinedale-1 glacial deposits just south of a Pinedale-2 end moraine. Plot (bottom) is a scarp profile generated from lidar elevation data.

Comparison of (a) 1904 Historical map with (b) 1988 USGS map. Colloidal Pool is a large, labeled pool roughly located on a straight line between Hurricane vent and Whirligig Geyser on the 1988 map (b); this same transect on the 1904 map (a) shows no feature at that location (white circle).

Different views of an eruption from two predictable geysers. (a, c) Graphs showing water temperatures recorded by data loggers stationed near Beehive and Old Faithful Geysers, respectively. These data loggers were deployed by the Yellowstone Geology Program, configured to capture temperatures at one-minute intervals (indicated by blue dots).
