Video has surfaced of a man walking on the Old Faithful geyser in Yellowstone National Park.

The video was shot by a park visitor on Friday, September 14.

The footage shows a man standing close to the center of the geyser. At one point, he lays down near the edge.

People close by can be heard yelling at him to “get off Old Faithful” and to “get on the boardwalk.”

The man was reportedly arrested shortly after the incident.
