Two hikers suffered injuries in a bear attack near Old Faithful in Yellowstone National Park on Monday, the National Park Service said.

A hydrothermal explosion at Yellowstone National Park sent steam, mud, and debris high into the air. The dramatic event poses no broader volcanic threat.

Two hikers sustained injuries in a bear attack on a popular trail near Yellowstone National Park's Old Faithful geyser, park officials announced Tuesday. The incident, described as a single event, occurred on Monday afternoon along the Mystic Falls Trail.

Two hikers were attacked by one or more bears, officials said, marking the first time in 2026 that a bear has injured people at Yellowstone.
