Hydrothermal explosion rocks Yellowstone's Black Diamond Pool again
The Yellowstone Volcano Observatory webcam captured the explosion at Black Diamond Pool in Biscuit Basin just before 9:30 a.m.
This is the same site that damaged a boardwalk and spewed debris several hundred feet into the air on July 23, 2024.
Biscuit Basin has remained closed to visitors since that July incident due to the extensive damage.
The closure prompted crews to install the monitoring camera to keep watch on future activity at the location.
