Yellowstone’s Biscuit Basin Sparks Fresh Steam Vents After Tiny Hydrothermal Burst
TL;DR
A small hydrothermal explosion at Biscuit Basin, Yellowstone, on June 13, 2026, created multiple new vents and steam-filled pools, with hot water reaching the Firehole River at about 194°F (90°C). By June 18 a new ground feature had become a vigorously boiling pool roughly 21 by 17 feet, and close-range monitoring captured this eruption on cameras about 100 meters away. The incident, following a larger 2024 blast, underscores the unpredictable, hazardous hydrothermal activity in the region and the ongoing need for monitoring to identify potential precursors.
