Yellowstone Boiling Pool Forms at 21-by-17 Feet, Spouting 30 Feet After Biscuit Basin Blast

Summary
A 21-by-17-foot boiling pool appeared in Yellowstone’s Biscuit Basin two days after a small June 13 hydrothermal explosion and was later seen spouting 20 to 30 feet like a geyser.
Monitoring gear near Black Diamond Pool recorded seismic energy and a low-frequency acoustic signal just after 5 a.m., while a camera captured a steam plume north of the pool.
Geologists found three new vent groups and fresh runoff channels carrying gray, silty water into the Firehole River, indicating the blast came from newly opened pathways rather than Black Diamond Pool itself.
The pool likely formed by collapse rather than debris buildup, and scientists have added temporary seismic stations to track how the vents evolve and whether any warning signals can be identified.
No one was hurt because Biscuit Basin has remained closed since the larger July 2024 explosion; scientists say the event underscores the area’s long-running hydrothermal hazard.
