Geyser Explodes at Yellowstone National Park Biscuit Basin

A hydrothermal explosion at Yellowstone National Park's Biscuit Basin Geyser sent tourists running for safety on Tuesday. The sudden eruption caused a column of hot water, mud, and rocks to shoot out of the ground, alarming visitors on a nearby walkway.

Despite the dramatic nature of the explosion, there have been no reports of injuries. However, the force of the eruption did cause damage to the boardwalk, prompting officials to temporarily close Biscuit Basin. The Grand Loop Road, a major thoroughfare in the park, remains open to visitors.
