Hydrothermal Explosion Closes Yellowstone's Biscuit Basin

Surprise Eruption Shuts Down Area Near Old Faithful

What Happened?

On Tuesday, July 23rd, at approximately 10:19 AM, a hydrothermal explosion occurred at Biscuit Basin in Yellowstone National Park, in northwest Wyoming. The explosion sent a column of boiling water, mud, and rock shooting into the air. There were no injuries reported.

Area Closed

The Biscuit Basin area of the park, which is located just north of Old Faithful, has been closed following the explosion. Park officials are assessing the damage and determining when it will be safe to reopen the area.

Hydrothermal Explosions

Hydrothermal explosions are caused by the sudden release of pressure from heated groundwater. These explosions can occur in areas with volcanic activity, such as Yellowstone National Park. In the past, hydrothermal explosions have occurred at Norris Geyser Basin in 1989 and at Biscuit Basin in 2009.

Safety Measures

Park officials are urging visitors to stay away from the closed area. They also remind visitors to always follow park regulations, including staying on designated trails and boardwalks, and not approaching wildlife.
