Aerial view of the Black Diamond Pool area of Biscuit Basin, Yellowstone National Park, showing the locations of northern, middle, and southern vent groups that formed as a result of a small hydrothermal explosion on June 13, 2026. The "new pool' developed later, between June 14 and 16.

Pool of boiling water that formed a few days after the June 13, 2026, hydrothermal explosion at Biscuit Basin, Yellowstone National Park, and that is located near the middle vent group of features that formed during the explosion. The pool is about 6.5 × 5.3 meters (21 × 17 feet) in size and formed via collapse based on the lack of surrounding ejecta.

Looking south, toward Black Diamond Pool (steaming blue area in the left middle ground) along a fissure that formed during a small hydrothermal explosion on June 13, 2026, in Biscuit Basin, Yellowstone National Park. The fissure is about 18.5 meters (61 feet) long and filled with near-boiling water.

Screen capture showing the view from the Biscuit Basin research and monitoring camera at 05:09:54 a.m. MDT on June 13, 2026. Black Diamond Pool is in the foreground, and a steam plume in the upper right marks the occurrence of a small hydrothermal explosion behind (to the north of) the pool.

Looking downstream along the Firehole River, Yellowstone National Park, from the Midway Geyser bridge on the morning of June 13, 2026. The milky colors are due to suspended sediment that flowed into the river as a result of a small hydrothermal explosion at Biscuit Basin, which is located a straight-line distance of about 5 kilometers (3.1 miles) upstream.

On June 13, 2026, Yellowstone National Park’s newest geophysical monitoring sites captured a small hydrothermal explosion in Biscuit Basin! That story is the subject of this month’s video update.

This video is from the Biscuit Basin camera, which is located on the boardwalk adjacent to Black Diamond Pool (the blue-water feature in the foreground) and looking to the north. Black Diamond Pool was the site of a hydrothermal explosion on July 23, 2024, and the pool has erupted numerous times since that event.

Summer is here, and millions of people will be visiting Yellowstone National Park. People with questions. What is this scat I’m seeing? How does a geyser erupt? What makes Yellowstone so special?
Where’s the bathroom?

Did you hear that??? Well, Roaring Mountain isn’t quite as loud as it used to be, but it’s still one of the hottest thermal areas in all of Yellowstone National Park!

KABOOM! That’s what Yellowstone is famous for – huge explosive volcanic eruptions. There’s really nothing brewing right now, the magma chamber is mostly solid, but there have been quite a few hydrothermal eruptions and small explosions in both Biscuit Basin and Norris Geyser Basin as water in the hydrothermal system flashes to steam.

The camera view is north-northwest from the Biscuit Basin boardwalk looking at Black Diamond Pool, which is in the foreground (the tilted viewing angle is due to the slope of the boardwalk).

This static image is from a USGS Cascades Volcano Observatory research camera located at the Johnston Ridge Observatory, north of Mount St. Helens. The view is to the south. This camera is intended to assist the USGS with situational awareness. At times, clouds, rain, and snow obscure visibility.
