A hydrothermal explosion sent a towering column of boiling water, mud and rock shooting into the air at Yellowstone National Park in Wyoming on Tuesday morning, destroying a section of boardwalk and sending dozens of tourists running for safety, officials said.
The explosion occurred at around 10 a.m. in the Biscuit Basin area of the park.
Several tourists captured video of the event, and in some footage an adult can be heard shouting at children to run.
Suddenly it became a huge, dark cloud full of rocks,” she said in a phone interview.
“It was a huge cloud, it covered the sun.
