Visitors at Yellowstone National Park on Tuesday witnessed a hydrothermal explosion that shot steam and debris into the air, the National Park Service confirmed.
The surprise eruption happened around 10:19 am at Biscuit Basin, a geothermal area about two miles from Old Faithful, the park’s iconic geyser that erupts daily.
No guests or park rangers were injured during the explosion, but some guests nearby captured the event on video. The National Park Service said the extent of damage is currently unknown.
