Seismic reflection data showing the top of the magma reservoir beneath Yellowstone Caldera along a cross section that runs from Canyon Village in the northwest (X) to near Lake Butte in the southeast (X`). The top panel shows seismic P-wave (compressional wave) reflectivity, with evidence for the sharp reservoir top labeled.

Quartz crystals (A) often contain melt embayments (tubular melt-filled pockets burrowed into the side of volcanic crystals) (B), which preserve volatiles (water, carbon dioxide, and sulfur) that have different concentrations in different parts of the embayment (C).

Range of speeds for several animals, athletes, and magmas from various volcanic eruptions. Eruptions shown include the 25,400-year-old Oruanui eruption of Taupo (New Zealand), the 2.08-million-year-old Huckleberry Ridge Tuff of Yellowstone (USA), and the 767,000-year-old Bishop Tuff of Long Valley (USA). Magma ascent rates determined by Myers et al. (2018).

Simplified schematic of a volcanic plume ejecting ash, crystals and fragments of rock from a vent. This rising plume will eventually hit a zone of neutral buoyancy in the atmosphere, where it is then carried by the wind. Material is ejected from both the upward moving jet and falls from the umbrellaing plume.

Well look at this mess! What’s going on?
We’re just south of Mammoth Hot Springs at a place informally known as the Hoodoos. The official designation for the area is Silver Gate, named by an early Yellowstone National Park visitor because of the way the road wound between the closely spaced white and gray boulders.

Is it true roads in Yellowstone National Park are melting? Whatever you might have heard, it's nothing new and it's not due to increased volcanic activity. Get up-to-speed in this month's update from the Yellowstone Volcano Observatory (March 2025).

You've probably seen videos of black smokers on the ocean floor, where hydrothermal fluids vent from chimneys. In Yellowstone’s Monument Geyser Basin, you can see similar features right at the surface, and they likely formed in much the same way. Watch to learn more.
