Seismic geyser in eruption in 1970.

Graphical abstract of the new research paper. The scientists collect samples from the rocks forming near hot springs and geysers. They dissolve small amounts of the rock in acid and organic carbon (created by living organisms) remains behind.

The solubility of amorphous silica (solid silica with no crystal structure) in water as a function of temperature. When deep groundwater flows through hot rhyolite it can remove silica from the rhyolite (dissolve silica).

This orthophoto of Pocket Basin, a hydrothermal explosion crater in Yellowstone National Park's Lower Geyser Basin, was created from aerial photos taken in 1965 that were corrected to have uniform scale for use in geologic mapping.

This house fell into Hebgen Lake during the 1959 earthquake and floated along the shore until it came to rest here. The owner of the house, then-70-year-old Mrs. Grace Miller, escaped only after kicking out her front door and leaping a 5-foot-wide ground crack as her house dropped into the lake.

Aerial view of Black Opal Pool, Black Diamond Pool, and part of Wall Pool, all in Biscuit Basin, Yellowstone National Park, taken in 1959 sometime after the Hebgen Lake earthquake (which occurred on August 17 of that year).

Dragline work to lower the outlet channel of Earthquake Lake on October 18, 1959. The tripod on the hill at center left is one of five lighting plants that allowed nighttime work. Note the “bathtub ring” of killed trees along the shoreline marking the high stand of Earthquake Lake before lowering of the outlet channel. Photo by Mrs. Steven W. Nile (Dr.

Beryl Spring is a hydrothermal area in some restrictive topography! The road from Norris Geyser Basin to Madison Junction follows the Gibbon River through a tight valley. With not much of a choice, the road threads between the river and Beryl Spring over some exceedingly hot ground.
