A scanned image of Rocky Mountain juniper deadwood sample GGR100 collected in the northern part of Yellowstone National Park under permit YELL-5582.  The full length of this sample covers the time period 723-1792 CE.

Radar image of the May 17, 2018 eruption of ash from Halema‘uma‘u Crater. This image is a slice through the cloud at an altitude of 14,000 ft (4 km) above sea level at 4:12 a.m., HST. The colors scale is radar reflectivity, a measure of the size of the particles and their concentration within the ash cloud.

Cross section through the Earth showing the ground surface with an embedded pressure source (red circle)—the so-called “Mogi model”—beneath the ground.  When this pressure source expands, the ground surface inflates like a balloon (the opposite occurs when the pressure in the source decreases).  Dashed black line shows, in an exaggerated way, how the shape

Photo looking north from the north shore of Yellowstone Lake. The photo was taken from a level bench, or terrace, which marks a previous high stand of the lake.  In the middle distance (between the two red lines), the ground slopes up to second, higher-level terrace that indicates an even higher past lake level.
