Image from the webcam installed at Biscuit Basin in Yellowstone National Park. The view is of Black Diamond Pool, where a hydrothermal explosion occurred on July 23, 2024 (many of the rocks behind and to the right of the pool were deposited during that event). The background cliff is the Summit Lake rhyolite lava flow, which is about 111,000 years old.&n

Temporary webcam deployed on the boardwalk in Biscuit Basin, Yellowstone National Park. The pan/tilt/zoom camera provides a static view every 15 minutes and records video on site for later download as needed. Black Diamond Pool, site of a hydrothermal explosion on July 23, 2024, is in the background. This work was completed under Yellowstone Nation

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).

There’s a lot of hot water in Yellowstone. What’s it heated by? The magma chamber beneath the surface, of course!

If you want to find a lava flow in Yellowstone, look to the trees! The vegetation is telling us more than you might think.
YVO Scientist-in-Charge Mike Poland reveals how vegetation can be used to map geology in this month's update from the Yellowstone Volcano Observatory.

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.

Need time to concentrate or relax? Then listen to the gurgling and bubbly sounds of Steamboat Geyser in Yellowstone National Park, Wyoming. "Steamboat Geyser is the world’s tallest active geyser. It showers watchers and drenches the walkway. Days, months, or years pass between the major eruptions of Steamboat Geyser.
